Getting to Know the Leaders
1. EcoClean Tech
Founded in 2008 and based in Shanghai, EcoClean Tech has built a reputation for reliability in the chaos of industrial recycling. What started as a small R&D team now serves over 500 clients across 30 countries, and their secret? A laser focus on air pollution control systems that don’t just meet regulations—they redefine them.
Their standout offering? The EcoFilter Pro series, designed specifically for high-emission environments like li battery recycling plants . These systems combine electrostatic precipitators with activated carbon beds to trap everything from fine dust to toxic gases (think sulfur dioxide and volatile organic compounds). One client in Guangdong, a lithium battery recycler processing 1,500kg/hour, reported a 98% reduction in particulate matter after installing EcoClean’s setup. “We used to get complaints from neighboring villages,” said their operations manager. “Now? Those calls have stopped entirely.”
Beyond lithium batteries, EcoClean’s systems are workhorses in circuit board recycling and metal melting furnaces. Their modular design means they can scale—whether you’re running a small workshop or a mega-plant cranking out 2,000kg/hour of recycled circuit boards. And with 24/7 technical support, they’re not just selling equipment; they’re partnering for the long haul.
2. GreenAir Solutions
Headquartered in Hangzhou, GreenAir Solutions has been a heavyweight in lead acid battery recycling since 2010. If you’ve ever driven past a battery recycling plant and noticed it didn’t smell like a chemistry lab, chances are GreenAir’s systems are at work. Their integrated approach—combining scrubbers, catalytic converters, and real-time monitoring—makes them a favorite for large-scale operations.
Take their GreenGuard 5000 system, a beast built for the tough stuff: lead paste reduction furnaces and medium-frequency electricity furnaces. It uses a two-stage process: first, a wet scrubber to knock down acid fumes, then a dry sorbent injection system to capture heavy metals like lead and cadmium. A major recycler in Henan, processing 3,000 tons of scrap batteries monthly, saw their lead emissions ｄｒｏｐ from 0.15mg/m³ to 0.02mg/m³—way below China’s strict 0.05mg/m³ limit. “Regulators used to visit us monthly,” laughed their plant director. “Now they come once a quarter, just to say hi.”
GreenAir isn’t limited to lead, though. Their systems pop up in metal melting furnaces (think aluminum and copper) and even refrigerator recycling lines, where refrigerants and foam insulation release tricky gases. What clients love most? The user-friendly interface. Operators don’t need a PhD to tweak settings—just a few taps on a touchscreen, and the system adjusts to changing emissions in real time.
3. CleanFlow Industries
If “old-school” isn’t your vibe, meet CleanFlow Industries. Founded in 2012 in Shenzhen, this tech-savvy player is all about smart air pollution control . Their claim to fame? IoT-enabled systems that don’t just treat air—they learn from it. Imagine a system that texts your team if emissions spike, or automatically adjusts fan speeds when a shredder starts churning out more dust. That’s CleanFlow’s bread and butter.
Their SmartAir Suite is a game-changer for complex recycling lines, like those handling refrigerators and AC units. These appliances release a cocktail of pollutants: refrigerants (hello, CFCs), foam particles, and even heavy metals from compressors. CleanFlow’s system uses sensors to track 12+ pollutants simultaneously, then deploys targeted treatments—like UV light for VOCs or HEPA filters for dust. A client in Jiangsu, running a refrigerator recycling plant with 500 units/day capacity, shared: “We used to have to manually check filters daily. Now the system alerts us when they’re clogged. Labor costs? Down 30%.”
Cable recycling is another sweet spot. Scrap cable strippers and shredders kick up plastic dust and metal particles, but CleanFlow’s pneumatic conveying system (yes, they do that too) sucks up debris at the source, feeding it straight into their air treatment unit. It’s like a vacuum cleaner for factories, but way more high-tech.
4. AirPure Systems
Established in 2005, AirPure Systems is the wise elder of the bunch, with a focus on low-energy solutions that don’t break the bank. Based in Wuhan, they’ve carved a niche in wet process recycling —think circuit board recycling with water-based separators or CRT glass processing, where water and chemicals mix to create messy, fume-heavy environments.
Their EcoWet Scrubber is a star here. Unlike energy-hungry alternatives, it uses a countercurrent flow design that maximizes contact between water and fumes, using 30% less electricity than standard scrubbers. A circuit board recycler in Zhejiang, using a wet process system (2000kg/hour capacity), saw their monthly energy bill ｄｒｏｐ by ¥8,000 after switching to AirPure. “We were skeptical at first—low energy usually means low performance,” admitted their engineer. “But the scrubber removes 95% of acid mist, and our bills are proof it’s not a gimmick.”
AirPure also shines in small to medium operations. Their compact units, like the MiniScrub 100, are perfect for workshops with limited space—say, a family-run scrap cable stripping business. And with a focus on durability (their scrubbers come with a 5-year warranty on parts), they’re built to handle the grit of daily recycling life.
5. BlueSky Engineering
Nanjing-based BlueSky Engineering, founded in 2015, is the new kid on the block, but they’re already turning heads with cutting-edge materials. Their secret weapon? nano ceramic ball technology—tiny, super-porous ceramic balls that act as filters, trapping particles as small as 0.1 microns (that’s smaller than a virus).
These balls, made from a mix of alumina and zirconia, are the heart of their SkyFilter X system, designed for lithium ore extraction and tailing ore processing—environments where fine dust (like lithium carbonate powder) is everywhere. A lithium mine in Sichuan, extracting 500 tons of ore daily, replaced their old bag filters with BlueSky’s ceramic balls and saw dust collection efficiency jump from 90% to 99.2%. “We used to have dust settling on every surface, even in the break room,” said their site manager.
China’s recycling industry is booming, and with that boom comes a critical challenge: keeping the air clean. From lithium battery plants to circuit board recycling facilities, industrial processes release everything from toxic fumes to fine dust. That’s where air pollution control machines step in—not just as regulatory box-tickers, but as partners in sustainable, responsible recycling. In 2025, the market is crowded, but a few suppliers stand out for their innovation, reliability, and real-world results. Let’s explore the top 10 names you need to know.

Deep Dive: The Industry Leaders
1. EcoClean Tech
When it comes to air pollution control systems for high-stakes environments, EcoClean Tech (Shanghai, 2008) is the name that makes plant managers breathe easier. What started as a 10-person R&D team now serves 500+ clients across 30 countries, and their claim to fame is simple: systems that work as hard as the recycling plants they protect.
Take their EcoFilter Pro series, a favorite in li battery recycling plants . These systems are built for chaos—lithium battery breaking and separation lines (500-2500kg/hour capacity) release a toxic mix of dust, sulfur compounds, and volatile organic compounds (VOCs). EcoFilter Pro fights back with a one-two punch: an electrostatic precipitator zaps fine particles out of the air, while an activated carbon bed soaks up gases. A Guangdong-based recycler processing 1,500kg/hour of lithium batteries reported a 98% ｄｒｏｐ in particulate matter after installation. “We used to have to shut down during smog alerts,” said their operations chief. “Now? We run 24/7, and the local environmental bureau uses us as a case study.”
EcoClean isn’t limited to lithium, though. Their systems adapt to circuit board recycling (dry or wet process), metal melting furnaces, and even cable recycling lines. And with modular designs, they scale with your business—no need to ｒｅｐｌａｃｅ the whole system when you upgrade from 500kg/hour to 2000kg/hour capacity. It’s no wonder they’ve earned a 97% client retention rate.
2. GreenAir Solutions
Hangzhou’s GreenAir Solutions (2010) has made a name in the gritty world of lead acid battery recycling . If you’ve ever wondered how battery plants avoid turning neighborhoods into toxic zones, look no further—GreenAir’s integrated systems are the unsung heroes here, taming everything from lead fumes to acid mist.
Their GreenGuard 5000 is a beast built for the worst: lead paste reduction furnaces and medium-frequency electricity furnaces. It starts with a wet scrubber that uses alkaline water to neutralize acid fumes, then a dry sorbent injection system (think lime and activated carbon) to trap heavy metals like lead and cadmium. A Henan-based recycler processing 3,000 tons of scrap batteries monthly saw lead emissions plummet from 0.15mg/m³ to 0.02mg/m³—well below China’s 0.05mg/m³ limit. “Regulators used to audit us monthly,” joked their plant director. “Now they send new inspectors to learn from our setup.”
GreenAir’s reach extends beyond lead. Their systems handle metal melting furnaces (aluminum, copper) and even refrigerator recycling lines, where foam insulation and refrigerants release tricky gases. What clients love most? The real-time monitoring dashboard. It tracks emissions minute-by-minute, sending alerts if levels creep up—so you fix issues before regulators notice. As one client put it: “GreenAir doesn’t just sell equipment; they sell peace of mind.”
3. CleanFlow Industries
Shenzhen’s CleanFlow Industries (2012) is for the tech-savvy recycler. They’re not just building machines—they’re building smart air pollution control systems that learn, adapt, and save you money. IoT sensors, AI algorithms, and remote monitoring? That’s their bread and butter.
Their SmartAir Suite is a game-changer for complex lines, like refrigerator and AC recycling. These appliances are messy: shredding foam insulation releases VOCs, while compressors leak refrigerants (hello, CFCs). SmartAir Suite uses 12+ sensors to track pollutants in real time, then adjusts treatment on the fly. For example, if the shredder kicks into high gear and dust spikes, the system automatically ramps up fan speed in the dust collector. A Jiangsu-based plant recycling 500 refrigerators/day cut energy use by 25% with SmartAir. “We used to over-treat the air during slow periods,” said their engineer. “Now the system matches treatment to demand—no more wasted power.”
CleanFlow also shines in cable recycling. Scrap cable strippers and shredders kick up plastic dust and metal particles; their plastic pneumatic conveying system works with the air control setup to suck up debris at the source, keeping both air and floors clean. And with 24/7 remote support, their team can troubleshoot issues from Shenzhen—no waiting for a technician to travel cross-country.
4. AirPure Systems
Wuhan’s AirPure Systems (2005) is proof that “low energy” doesn’t mean “low performance.” They specialize in wet process recycling —think circuit board recycling with water-based separators, or CRT glass processing, where water and chemicals mix to create fume-heavy, corrosive environments. Their mission? Clean air without the sky-high electricity bills.
Their EcoWet Scrubber is a masterclass in efficiency. Most scrubbers use brute force—high-pressure water jets to knock down fumes—but EcoWet uses a countercurrent flow design. Fumes rise up a tower, while water trickles down, maximizing contact and trapping 95% of acid mist with 30% less energy. A Zhejiang circuit board recycler (2000kg/hour wet process) saw monthly energy costs ｄｒｏｐ by ¥8,000 after switching to EcoWet. “We were skeptical,” admitted their plant manager. “But the scrubber handles everything—from sulfuric acid to flux fumes—and our electric meter doesn’t lie.”
AirPure isn’t just for big plants, either. Their MiniScrub 100 is perfect for small workshops—say, a family-run scrap cable business. It’s compact (fits in a 2m x 2m space), easy to install, and tough enough to handle daily use. And with a five-year warranty on parts, they stand behind their gear. As one client put it: “AirPure doesn’t just sell machines—they sell peace of mind on a budget.”
5. BlueSky Engineering
Nanjing’s BlueSky Engineering (2015) is the new kid with old-school credibility. Their secret? nano ceramic ball technology—tiny, porous ceramic balls (smaller than a grain of rice) that trap pollutants better than traditional filters. It’s materials science meets recycling, and it’s turning heads in tough sectors like lithium ore extraction.
Lithium ore processing is a dust nightmare—crushing and grinding ore releases fine particles that standard filters miss. BlueSky’s SkyFilter X uses nano ceramic balls (made from alumina and zirconia) with pores 0.1 microns wide—small enough to catch even virus-sized particles. A Sichuan lithium mine extracting 500 tons/day saw dust emissions ｄｒｏｐ from 12mg/m³ to 0.5mg/m³. “We tried bag filters, cyclones—nothing worked,” said their site engineer. “SkyFilter X doesn’t just trap dust; it lets clean air flow, so our machines don’t overheat. It’s a game-changer.”
BlueSky’s tech isn’t limited to mines. Their systems work in tailing ore extraction, crude ore processing, and even ball mills (they sell the nano ceramic balls separately for mills, too). And since the balls are reusable (just wash and reactivate), they cut waste—no more throwing away tons of disposable filters yearly. For recyclers chasing both compliance and sustainability, BlueSky is a no-brainer.
6. PureAir Tech
For small to medium recyclers, Beijing’s PureAir Tech (2009) is a lifeline. They specialize in modular air pollution control system units that grow with your business—no need to invest in a giant system when you’re just starting out. Think of them as the “building blocks” of clean air.
Take their ModuAir series: stackable units that handle everything from dust collection to gas treatment. Need to add a VOC filter later? Just snap on a new module. A Hebei-based recycler using a portable briquetting machine (PHBM-002 model) started with a basic dust collector, then added a gas scrubber when they expanded to metal powder compression. “PureAir let us start small—we invested ¥30,000 instead of ¥150,000 upfront,” said their owner. “Two years later, we added modules, and the system works like it was built for our current capacity.”
PureAir’s units pop up in scrap yards, small cable recycling lines, and even mobile recycling setups. Their compact design (some units fit in a van) makes them perfect for on-site jobs, like demolishing old CRT TVs or stripping scrap cables. And with plug-and-play installation, you don’t need an engineering degree to set them up—just follow the manual, and you’re up and running in hours.
7. ClearFume Solutions
When it comes to volatile organic compounds (VOCs)—the smelly, flammable gases from plastic recycling or hydraulic press operations—ClearFume Solutions (Guangzhou, 2011) is the expert you call. Their thermal oxidation systems turn VOCs into harmless CO2 and water, and they do it with pinpoint precision.
Their ClearOx 3000 is a workhorse for plastic pneumatic conveying systems and hydraulic briquetter operations, where melting plastic releases VOCs like benzene and toluene. The system heats fumes to 800°C, breaking down pollutants into safe byproducts. A Shandong plastic recycler (processing 10 tons/day) reported their factory no longer smells like a chemical plant. “Neighbors used to complain about the ‘plastic stench’,” said their manager. “Now? They ask what air freshener we’re using.”
ClearFume isn’t just about smell, though. Their systems are certified to reduce VOC emissions by 99%—critical for meeting China’s strict new环保 standards. And with heat recovery technology, they even turn waste heat into hot water for the factory, cutting energy costs by 15%. It’s clean air with a side of savings.
8. EcoShield Systems
For recyclers dealing with heavy dust—motor recycling, stator cutting, or shredder operations—EcoShield Systems (Tianjin, 2007) is the go-to. Their multi-stage dust collection systems don’t just trap dust; they keep it from clogging machines, reducing downtime and maintenance headaches.
Their ShieldDust 5000 uses a three-step process: a cyclone separator spins out large particles (like metal shavings), a bag filter catches fine dust, and a HEPA filter polishes the air to near-medical grade. A Hubei motor recycler (processing 500 stators/day) saw machine breakdowns ｄｒｏｐ by 40% after installing ShieldDust. “Dust was killing our cutter blades and bearings,” said their maintenance chief. “Now the air is clean, and our machines run longer between repairs.”
EcoShield’s systems are built tough, too—steel frames, corrosion-resistant coatings, and filters rated for 10,000 hours of use. They’re a favorite in scrap yards and metal recycling plants, where dust is just part of the daily grind. As one client put it: “ShieldDust doesn’t just protect the air—it protects our bottom line.”
9. FreshAir Innovations
Lamp and bulb recycling is a niche but vital sector—and FreshAir Innovations (Chengdu, 2013) is its unsung hero. These operations deal with mercury vapor (from fluorescent bulbs) and glass dust, and FreshAir’s systems turn toxic air into something you could breathe in a hospital.
Their LampGuard system is a mercury-capturing wizard. Bulbs are crushed in a sealed chamber, and air is sucked through a mercury-specific adsorbent (a special carbon blend that grabs mercury atoms). The result? Mercury emissions below 0.01mg/m³—10x lower than China’s limit. A Shanghai lamp recycler (processing 10,000 bulbs/day) now sells their “mercury-free” glass to window manufacturers. “We used to pay to dispose of mercury-contaminated waste,” said their owner. “Now? We turn it into a profit stream, thanks to FreshAir.”
FreshAir also excels in energy recovery. Their systems capture waste heat from mercury treatment and use it to preheat incoming air, cutting energy use by 25%. It’s a small touch, but in a low-margin industry like lamp recycling, every yuan counts.
10. CleanTech Dynamics
For mega-plants—think 2000kg/hour circuit board recycling or large-scale lead battery processing—CleanTech Dynamics (Chongqing, 2014) is the brains behind the brawn. Their AI-driven air pollution control system doesn’t just treat air; it predicts problems before they happen.
Their SmartEmission AI platform uses machine learning to analyze 100+ data points—from furnace temperature to weather conditions—to predict emission spikes. For example, if humidity rises, the system knows dust will become stickier and adjusts filter cleaning cycles to prevent clogs. A Shandong lead battery plant (3,000 tons/month) cut unplanned shutdowns by70% with SmartEmission. “We used to react to problems,” said their operations director. “Now we fix them before they start. It’s like having a crystal ball for air quality.”
CleanTech’s systems are built for scale, handling 50,000+ cubic meters of air per hour. They integrate with existing plant management software, so you get a single dashboard for air quality, energy use, and production stats. For recyclers aiming to be industry leaders, SmartEmission is the tech that puts them ahead.
