Top 10 Air Pollution Control Machine Suppliers and Manufacturers in China

With over 25 years in the industry, EcoGuard has built a reputation as a pioneer in air pollution control. Starting as a small workshop in Jiangsu, the company now operates three state-of-the-art manufacturing facilities and serves clients in Europe, Southeast Asia, and North America. What truly sets them apart is their focus on air pollution control system equipment that integrates seamlessly with industrial processes—no more clunky add-ons that disrupt workflow.

Their product lineup includes de-sulfurization machines equipment that efficiently removes sulfur dioxide from flue gases, a common byproduct in metal smelting and battery recycling. Paired with their filter press equipment , which separates solid particles from wastewater, EcoGuard’s systems ensure both air and water emissions meet even the strictest global standards. “We don’t just sell machines—we sell peace of mind,” says their sales director. “Many of our clients come to us after struggling with non-compliant equipment, and within months, they’re seeing 90%+ reduction in emissions.”

Notable projects include a lead acid battery recycling plant in Germany, where EcoGuard’s custom system cut harmful emissions by 97% and reduced operational costs by 15% through energy-efficient design. It’s no wonder they hold ISO 14001 certification and have a 95% client retention rate.

CleanAir Solutions Group made a name for itself by prioritizing energy efficiency—because what’s the point of cleaning the air if you’re wasting electricity to do it? Founded in Zhejiang, this company has grown to become a favorite among manufacturers looking to balance环保 (environmental protection) and profitability. Their air pollution control systems are designed to use up to 30% less energy than industry averages, a feature that resonates with factories facing rising utility costs.

One of their standout products is the “EcoScrubber,” a wet scrubber that uses a water-based solution to trap pollutants. Unlike traditional scrubbers that require constant water replacement, the EcoScrubber recycles 80% of its water, making it ideal for water-scarce regions. “We worked with a copper mine in Chile last year,” explains an engineer at CleanAir. “Their old system used 5,000 liters of water daily; ours uses 1,000. They’re saving money and helping the planet—win-win.”

CleanAir also excels in after-sales support. Every system comes with a 5-year warranty and access to a 24/7 technical hotline. Their team even offers on-site training to ensure operators know how to get the most out of the equipment. It’s this attention to detail that has earned them partnerships with big names like Samsung and BASF.

Don’t let their relatively young age fool you—GreenTech Engineering has quickly become a leader in innovative air pollution control. Founded by a team of environmental engineers from Tsinghua University, the company prides itself on “solving problems others can’t.” Their secret? A relentless focus on R&D, with 20% of annual revenue reinvested into new technologies.

Take their dry scrubbers, for example. Traditional wet scrubbers are effective but messy; GreenTech’s dry version uses alkaline powders to neutralize acids in the air, producing minimal waste. “We had a client in the pharmaceutical industry who couldn’t use wet scrubbers because moisture would ruin their products,” says their R&D head. “Our dry scrubber fit perfectly—no water, no mess, just clean air.”

GreenTech also specializes in custom solutions. If your factory has unique layout constraints or processes, their team will visit your site, conduct a detailed analysis, and design a system from scratch. This flexibility has made them a go-to for small and medium enterprises (SMEs) that can’t afford off-the-shelf, one-size-fits-all equipment. “SMEs are the backbone of manufacturing, but they often get overlooked,” notes their CEO. “We want to make clean air accessible to everyone, not just the big players.”

Today, GreenTech’s footprint spans 50+ countries, with recent expansions into Africa and South America. Their systems are used in everything from food processing plants (to control odors) to circuit board recycling facilities (to capture toxic fumes).

AirPure Manufacturing is all about durability. Their equipment is built to last—15 years on average, compared to the industry standard of 8-10. “We use high-grade stainless steel and wear-resistant coatings,” explains their production manager, “so even in harsh environments like steel mills, our machines keep running with minimal maintenance.”

Their flagship product is the “DuraFilter,” an electrostatic precipitator that uses an electric charge to trap dust particles. Unlike bag filters that need frequent replacement, the DuraFilter’s collection plates can be cleaned with a simple wash, saving time and money. A steel plant in India reported reducing filter replacement costs by 70% after switching to AirPure’s system.

AirPure also offers filter press equipment that’s a hit in the mining sector. These machines separate solids from liquids with precision, turning waste sludge into dry cake that can be repurposed or safely disposed of. “One gold mine in Australia was spending $50,000 monthly on sludge disposal,” says a client testimonial. “With AirPure’s filter press, we now produce dry cake that’s sold as construction material—we went from a cost center to a profit center!”

While their equipment isn’t the cheapest on the market, clients say the long-term savings more than make up for the initial investment. As one plant manager put it: “You pay a little more upfront, but you never regret it. AirPure’s machines just… work.”

Sustainable Air Systems (SAS) has carved a niche in a high-growth sector: lithium battery recycling. As the world shifts to electric vehicles, the demand for recycling lithium-ion batteries is skyrocketing—and with it, the need to control toxic emissions like lithium dust and volatile organic compounds (VOCs).

SAS’s air pollution control system for li battery recycling plant is a game-changer. It combines a multi-stage filtration process: first, a cyclone separator to catch large particles, then a HEPA filter for fine dust, and finally a UV oxidizer to break down VOCs. The result? 99% removal of harmful pollutants, as verified by third-party labs. “Lithium battery recycling is a new field, so many suppliers are still figuring it out,” says SAS’s technical director. “We’ve been refining our systems for 15 years—we know exactly what these plants need.”

What clients love most is SAS’s “turnkey” approach. They handle everything from design and installation to staff training, so plant operators can focus on their core business. A lithium battery recycler in Canada shared: “We were up and running in 8 weeks, which is unheard of in this industry. SAS even sent a technician to stay on-site for the first month to make sure everything ran smoothly.”

With the global lithium battery recycling market projected to grow 25% annually, SAS is poised to become an even bigger player. Their recent partnership with a major EV manufacturer in China only solidifies their position as a leader in this space.

BlueSky Environmental Equipment is the budget-friendly option that doesn’t skimp on quality. Their mission is to make air pollution control accessible to small factories and startups, which is why their systems start at half the price of premium brands. “We cut costs by simplifying designs without compromising performance,” says their founder. “For example, our basic de-sulfurization machine has fewer moving parts, but it still removes 92% of sulfur dioxide—more than enough for most SMEs.”

Their modular systems are another plus. Instead of buying a full-scale setup upfront, clients can start with a basic unit and add components (like extra filters or scrubbers) as their business grows. A plastic recycling plant in Vietnam did just that: they began with a small dust collector and, two years later, expanded to a full air pollution control system with BlueSky’s easy-to-upgrade modules.

BlueSky also offers flexible payment plans, including leasing options, to ease the financial burden on new businesses. “We believe no one should have to choose between profitability and sustainability,” says their sales team. It’s this customer-centric approach that has helped them build a loyal following across Asia and Latin America.

EnviroShield Tech is the innovator of the bunch, constantly pushing the boundaries of air pollution control technology. Their latest breakthrough? A plasma air purifier that uses high-energy plasma to break down pollutants at the molecular level. “Traditional filters trap pollutants; we destroy them,” explains their chief scientist. “It’s like having a mini lightning storm inside the machine—except controlled and safe.”

This technology is a hit in the chemical industry, where toxic fumes are hard to filter with conventional methods. A pesticide plant in Brazil reported eliminating 99.5% of harmful VOCs after installing EnviroShield’s plasma system, something they’d struggled with for years using traditional scrubbers.

EnviroShield’s equipment is also compact, making it ideal for factories with limited space. Their “MiniPurge” unit, designed for small workshops, is about the size of a refrigerator but can clean 500 cubic meters of air per hour. “We have a client who runs a jewelry workshop in a 500 sq ft space,” says their marketing manager. “The MiniPurge sits quietly in the corner, and now their workers no longer complain about fumes.”

While they’re still a smaller player compared to industry giants, EnviroShield’s focus on cutting-edge tech has earned them a spot on our list—and we expect big things from them in the next decade.

AirWorks Machinery specializes in high-temperature environments. Their equipment can withstand temperatures up to 1,200°C, making them a top choice for foundries, glass manufacturers, and metal melting furnaces. “Most air pollution control systems fail in extreme heat,” says their engineering lead. “Ours use ceramic heat exchangers and heat-resistant alloys, so they keep working even when the factory floor feels like a sauna.”

One of their most popular products is the “HeatShield” cyclone separator, which removes molten particles from hot gases. A aluminum foundry in the UK shared: “Before AirWorks, we had to shut down production every week to ｒｅｐｌａｃｅ melted filters. Now, the HeatShield runs 24/7, and we clean it once a month. Productivity is up, and downtime is practically zero.”

AirWorks also offers custom insulation solutions to prevent heat loss, which not only protects their equipment but also helps factories save on energy costs. “A steel mill in China reduced their heating bill by 22% after installing our insulated ductwork,” notes their client success manager. It’s this combination of durability and energy efficiency that keeps clients coming back.

PureAir Engineering is all about flexibility. Their movable air pollution control systems are mounted on wheels, so they can be rolled wherever they’re needed—no fixed installation required. “We designed them for factories with temporary projects or changing layouts,” says their founder. “Why build a permanent system when you might need to move it next year?”

Their “MobileClean” unit is a hit with construction companies and event venues. It’s compact enough to fit in a truck but powerful enough to clean 2,000 cubic meters of air per hour. A construction site in Dubai used three MobileClean units during a renovation project, keeping dust levels below regulatory limits and avoiding costly fines.

PureAir also offers rental options, which is perfect for short-term projects. “A food festival in Singapore rented our units for a month,” says their rental manager. “They needed to control cooking odors, and renting was cheaper than buying. Plus, we handled delivery, setup, and pickup—zero hassle for them.”

While they’re still building their reputation, PureAir’s innovative approach to mobility has earned them a loyal customer base in the construction and event industries. We expect to see them expand into more sectors as businesses look for agile, cost-effective pollution control solutions.

EcoSolutions Manufacturing takes a holistic approach to air pollution control. Their integrated systems don’t just clean the air—they recover waste heat and reuse it, turning a cost center into an energy saver. “Why let all that hot air go to waste?” asks their CEO. “Our systems capture heat from flue gases and use it to heat water or power turbines, reducing reliance on fossil fuels.”

One of their clients, a chemical plant in France, reported saving €200,000 annually on energy costs after installing EcoSolutions’ integrated system. “We’re not just reducing emissions—we’re increasing profitability,” the plant manager noted. “It’s a win for the environment and the bottom line.”

EcoSolutions also offers smart monitoring tools that track emissions in real-time and send alerts if levels rise. Their app lets managers check air quality from anywhere, ensuring compliance even when they’re off-site. “A battery recycling plant in the US avoided a $150,000 fine because our app alerted them to a filter leak before inspectors arrived,” says their tech director. “That’s the power of smart pollution control.”
