Top 5 Air Pollution Control System Suppliers in China [2025]

When it comes to air pollution control for high-stakes industries like lithium battery recycling, EcoClean Solutions has emerged as a name that industry insiders trust. Founded in 2010 and based in Hangzhou, this company has carved a niche by focusing on the unique challenges of lithium-ion battery processing—think toxic fumes from electrolytes, fine particulate matter from electrode materials, and volatile organic compounds (VOCs) released during shredding and separation.

What really sets them apart is their air pollution control system for li battery recycling plant designs. Unlike one-size-fits-all systems, EcoClean’s engineers work closely with clients to map out every step of the recycling process, then tailor their purification setups to target specific pollutants. Take their recent project with a major lithium battery recycler in Jiangsu: the client needed to handle 1,500 kg/h of battery modules, which meant dealing with a mix of sulfur hexafluoride (a potent greenhouse gas) and lithium cobalt oxide dust. EcoClean’s solution? A three-stage system combining a pre-cooling tower to condense heavy fumes, an electrostatic precipitator to capture 99.8% of particulates, and a catalytic oxidizer that breaks down VOCs into harmless CO2 and water. “We used to struggle with emissions that kept triggering local environmental alerts,” said a plant manager at the Jiangsu facility. “Since installing EcoClean’s system, we’ve passed every inspection with zero violations—and our workers no longer complain about eye irritation or headaches.”

Beyond lithium batteries, EcoClean also offers complementary equipment like filter press equipment to handle wastewater from wet separation processes, ensuring that air and water pollution are tackled as a single, integrated problem. Their commitment to R&D is another plus—they recently patented a self-cleaning filter technology that reduces maintenance downtime by 40%, a huge win for plants operating 24/7.

If EcoClean is a specialist, GreenGuard Environmental is the versatile expert that can handle just about any recycling scenario. Headquartered in Guangzhou, this supplier has built its reputation on adaptability, offering air pollution control systems for everything from circuit board recycling plant with dry separator setups to refrigerator and AC recycling lines. What makes them a top choice? Their ability to scale—whether you’re a small scrapyard processing 500 kg/h of circuit boards or a mega-plant handling 2,000 kg/h of refrigerators, GreenGuard has a system that fits.

Let’s take their work in circuit board recycling as an example. Shredding PCBs releases a cocktail of pollutants: brominated flame retardants (from plastic casings), lead and cadmium dust (from solder), and fiberglass particles. GreenGuard’s dry separator配套系统 uses a high-efficiency cyclone to spin out large debris first, followed by a baghouse filter with nano-coating that traps particles as small as 0.3 microns. But here’s the clever part: their system integrates with the dry separator’s airflow, using the same ventilation network to minimize energy use. A client in Zhejiang who upgraded to GreenGuard’s setup reported a 30% ｄｒｏｐ in electricity bills compared to their old standalone air cleaner. “We were skeptical at first—how could one system handle both separation and pollution control?” said the client’s operations director. “Now we’re saving money and meeting emissions standards we never thought possible.”

GreenGuard also excels in handling mixed waste streams, like refrigerator recycling. When you shred a fridge, you’re dealing with foam insulation fumes, refrigerant gases (like CFCs), and metal dust. Their systems include a dedicated refrigerant extraction machine to capture and recycle coolants before they escape, paired with activated carbon beds to吸附 odors and harmful chemicals. It’s this attention to the “hidden” pollutants that makes them a favorite among clients who prioritize full compliance with China’s strictest environmental laws.

For recycling plants that want to stay ahead of the curve, CleanAir Tech Co. in Shenzhen is leading the charge with smart, data-driven air pollution control. Founded by a team of former tech engineers, this company believes that the future of pollution control isn’t just about cleaning air—it’s about predicting and preventing issues before they arise.

Their flagship product, the SmartPurify 3000, is a game-changer. Equipped with IoT sensors that monitor pollutant levels in real time, the system adjusts fan speeds, filter backwashing cycles, and chemical injection rates automatically. For example, if a sudden spike in lead dust is detected during battery breaking, the system ramps up airflow to capture it faster, then sends an alert to the plant’s management app. “It’s like having a 24/7 environmental engineer on site,” laughed a plant manager at a lead acid battery recycling facility in Hebei. “Last month, the system flagged a clogged filter before it caused a pressure ｄｒｏｐ—we avoided what could have been a 6-hour shutdown.”

CleanAir Tech also specializes in energy efficiency. Their air pollution control system equipment uses variable frequency drives (VFDs) to match power usage to actual needs, cutting energy consumption by up to 25% compared to traditional systems. And for clients worried about downtime, their predictive maintenance feature analyzes sensor data to forecast when filters or parts need replacing, allowing for scheduled repairs instead of emergency fixes. In an industry where every hour of downtime costs thousands, this has made CleanAir a go-to for busy operations.

For international clients or Chinese recyclers aiming to export their products to Europe or North America, PurifyMax Engineering is the supplier that bridges the gap between global environmental standards and local manufacturing costs. With offices in Shanghai and Berlin, this company prides itself on systems that meet EU’s strict REACH and RoHS regulations, as well as China’s own ultra-low emission standards (ULES).

Their expertise shines brightest in complex, multi-pollutant scenarios, such as jelly-filled-cable recycling plant operations. Jelly-filled cables contain petroleum-based gels, PVC insulation, and metal conductors—when processed, they release toxic黑烟, hydrochloric acid fumes (from PVC), and polycyclic aromatic hydrocarbons (PAHs). PurifyMax’s solution? A thermal oxidizer that runs at 850°C to incinerate PAHs, followed by a scrubber tower filled with lime to neutralize acid gases, and a HEPA filter for any remaining particulates. The result? Emissions that are not just compliant, but often cleaner than the air in many cities. A French cable recycler that imported PurifyMax’s system noted, “We tested three suppliers, and only PurifyMax could get our HCl emissions below 5 mg/m³—something even our local European suppliers couldn’t match, at half the price.”

Another area where PurifyMax stands out is after-sales support. They offer 24/7 multilingual technical support, and their spare parts warehouse in Rotterdam ensures European clients get replacements in 48 hours or less. For Chinese clients exporting recycled materials, this peace of mind is invaluable—no more worrying about shipments being rejected due to non-compliant emissions records.

Last but far from least, EcoSphere Systems in Wuhan has made a name for itself by focusing on small and mid-size recyclers—the backbone of China’s recycling industry. While big players can afford million-dollar systems, smaller operations often struggle to find affordable, effective air pollution control. EcoSphere fills that gap with compact, budget-friendly setups that don’t skimp on performance.

Take their most popular model, the EcoMini 500, designed for plants processing 500-1,000 kg/h of materials like scrap cables or small electronics. Despite its small footprint (about the size of a shipping container), the EcoMini packs a punch: a cyclone separator, a cartridge filter with long-lasting media, and a UV-C light module to break down simple VOCs. It’s plug-and-play, too—most clients can install it themselves with EcoSphere’s video tutorials, saving on installation costs. “As a family-run cable recycling shop in Henan, we couldn’t afford the big systems,” said a satisfied customer. “The EcoMini cost us 60% less than the next cheapest option, and it still keeps our workshop air clean enough that my workers don’t wear masks anymore.”

EcoSphere also offers mobile units, perfect for recyclers who process materials at multiple sites. Their portable air scrubbers can be hitched to a truck and set up in under an hour, making them ideal for temporary projects or remote locations. And unlike some budget suppliers, they don’t cut corners on durability—their systems use corrosion-resistant steel and heavy-duty fans built to withstand the gritty, dusty environments of recycling yards.
