Top 10 Air Pollution Control System Suppliers for Lithium Battery Recycling Plants in China: A Definitive Guide

1. GreenGuard Environmental Tech Co., Ltd.

Founded: 2008 | Headquarters: Shanghai | Key Focus: Integrated APC systems for LiB recycling

GreenGuard isn’t just another environmental tech firm—they’ve been in the trenches with lithium battery recyclers for over a decade. What sets them apart? Their air pollution control system for li battery recycling plant is a one-stop shop, combining dust collectors, acid gas scrubbers, and VOC oxidizers in a single, streamlined setup. No more cobbling together components from different vendors.

Take their flagship “EcoShield LiB Series.” It starts with a high-efficiency cyclone pre-separator to catch large dust particles, then moves to a baghouse filter with PTFE-coated bags (perfect for sticky LiB dust). For acid gases like HF, they use a two-stage scrubber with alkaline spray, and a catalytic oxidizer handles VOCs. We spoke to a recycler in Guangdong who installed the EcoShield system last year—they reported a 98% reduction in particulate emissions and passed their environmental audit with zero violations.

GreenGuard also shines in customization. If your plant uses a dry process (like pyrolysis) versus a wet process, they’ll tweak the system to match. Their after-sales team is responsive too—critical when you need filter replacements or troubleshooting fast.

2. CleanAir Solutions (Nanjing) Co., Ltd.

Founded: 2012 | Headquarters: Nanjing | Key Focus: Low-energy APC systems for mid-sized plants

If you’re running a mid-sized recycling facility (processing 500–2,000 kg/hour), CleanAir Solutions is worth a hard look. They’ve built a reputation for balancing performance with affordability, and their systems are surprisingly energy-efficient—important when utility costs are eating into your margins.

Their “LiClean 5000” system is a crowd favorite. It uses a modular design, so you can start small and add components as you scale. For example, if you begin with shredding and sorting, you might just need their dust collector and scrubber. Later, when you add pyrolysis, you can bolt on a VOC oxidizer without overhauling the entire system. A recycler in Jiangsu told us they saved 15% on energy bills compared to their old, one-size-fits-all APC setup.

CleanAir also gets points for user-friendliness. Their touchscreen control panel lets operators monitor pressure drops, filter status, and emissions in real time—no need for a dedicated environmental engineer on staff. And yes, they’re fully compliant with China’s latest emissions standards, including GB 30484-2013.

3. AirPure Engineering Group

Founded: 2005 | Headquarters: Shenzhen | Key Focus: High-capacity systems for mega-plants

When we talk about large-scale lithium battery recycling—think 2,500+ kg/hour—AirPure is the name that comes up. They’ve supplied systems to some of China’s biggest recyclers, including a major facility in Hubei that processes over 10,000 tons of LiBs annually.

Their “MegaClean LiB Series” is built for volume. The system can handle up to 50,000 m³/h of air flow, with multiple parallel processing lines to avoid bottlenecks. What’s impressive is their attention to heavy metals. LiB recycling often involves trace amounts of lead (from battery casings) and cadmium, and AirPure’s electrostatic precipitators (ESPs) are designed to capture these fine particles that standard filters might miss.

We should note: AirPure systems aren’t cheap, but they’re built to last. Their equipment comes with a 5-year warranty on major components, and they offer on-site training for your maintenance team. If you’re scaling to meet the demand from EV manufacturers, AirPure is a safe bet for reliability.

4. EcoTech Innovations Co., Ltd.

Founded: 2015 | Headquarters: Hangzhou | Key Focus: Smart, IoT-integrated APC systems

EcoTech is the new kid on the block, but they’re making waves with their tech-forward approach. Their APC systems aren’t just about cleaning air—they’re about data. Every EcoTech system comes with IoT sensors that feed real-time data to a cloud dashboard, so you can track emissions, filter life, and energy use from your phone or laptop.

Their “SmartGuard LiB” system uses AI to predict maintenance needs. For example, if the pressure ｄｒｏｐ in the baghouse starts rising faster than normal, the system sends an alert, letting you schedule filter changes before a breakdown. A recycler in Zhejiang told us this feature cut their unplanned downtime by 40%.

EcoTech also specializes in compact designs, which is a lifesaver if your plant has limited space. Their vertical scrubber towers take up 30% less floor area than traditional horizontal setups. And for startups, they offer flexible financing options—something you don’t see from older, more established suppliers.

5. PurifyAir Environmental Equipment Co., Ltd.

Founded: 2010 | Headquarters: Guangzhou | Key Focus: Cost-effective solutions for small to mid-sized plants

Not every recycler needs a multi-million-dollar APC system. If you’re just starting out or processing 500–1,000 kg/hour, PurifyAir offers reliable, budget-friendly options. Their “BasicShield LiB” package includes a cyclone dust collector, a single-stage scrubber, and a simple VOC filter—all you need to meet basic emission standards without overspending.

What we like about PurifyAir is their transparency. They provide detailed energy consumption estimates upfront, so there are no surprises on your utility bill. They also offer a “Compliance Guarantee”: if their system doesn’t meet GB 30484-2013 standards within 3 months, they’ll tweak it for free. A small recycler in Anhui shared that they chose PurifyAir because “they didn’t try to sell us features we didn’t need—just a system that works.”

6. BlueSky Environmental Systems

Founded: 2006 | Headquarters: Chengdu | Key Focus: Specialized in HF and acid gas control

Hydrogen fluoride (HF) is one of the trickiest pollutants in LiB recycling—it’s corrosive, toxic, and hard to capture. BlueSky has made it their mission to master HF control, and their acid gas scrubbers are industry leaders. Their “HF-Capture Pro” uses a proprietary alkaline mist technology that neutralizes HF with over 99% efficiency, according to third-party lab tests.

BlueSky systems are also designed to handle the high humidity common in wet-process recycling. Many APC filters struggle with moisture, but their polypropylene scrubber packing resists clogging, even in steamy environments. A recycler in Sichuan that uses a wet leaching process told us, “Before BlueSky, our HF emissions were always on the edge of compliance. Now, they’re undetectable in our stack tests.”

7. EnviroFlow Tech Co., Ltd.

Founded: 2013 | Headquarters: Wuhan | Key Focus: Mobile and modular APC units

Not all recycling operations are permanent. Maybe you’re testing a new process, or you need to add temporary capacity during peak seasons. EnviroFlow’s mobile APC units are game-changers. Their “MobileGuard LiB” is mounted on a trailer, so you can move it to wherever pollution is highest—whether that’s near the shredder, pyrolysis unit, or smelter.

These units aren’t just for emergencies, though. They’re fully functional, with dust collectors, scrubbers, and VOC filters, and can handle up to 5,000 m³/h of air flow. We spoke to a recycler in Shandong who uses three MobileGuard units to cover different process lines—they save on installation costs by avoiding permanent ductwork.

8. CleanWave Environmental Engineering

Founded: 2011 | Headquarters: Suzhou | Key Focus: Noise reduction + air purification

Here’s a unique angle: CleanWave designs APC systems that also cut down on noise pollution. Lithium battery recycling is loud—shredders, separators, and compressors can hit 90+ decibels. CleanWave’s systems include acoustic enclosures and silencers, turning two problems (air pollution and noise) into one solution.

Their “QuietClean LiB Series” uses double-walled ductwork with sound-absorbing insulation, and their fans are engineered for low vibration. A recycler in Jiangsu near a residential area told us, “Before CleanWave, we had constant complaints from neighbors about noise. Now, they don’t even know we’re here—and our air emissions are cleaner than ever.”

9. GreenCycle Systems Co., Ltd.

Founded: 2016 | Headquarters: Qingdao | Key Focus: Circular economy—pollutant to resource

GreenCycle takes “sustainability” to the next level by turning captured pollutants into reusable resources. For example, their dust collectors recover lithium-rich particles that can be reprocessed into battery materials, and their acid scrubbers produce a neutralized salt byproduct that’s sold to chemical manufacturers. It’s not just about compliance—it’s about turning waste into revenue.

Their “ResourceRecover LiB” system isn’t cheap, but the ROI can be impressive. A recycler in Shandong reported recouping 30% of their APC investment within two years by selling recovered materials. “It’s like getting paid to clean the air,” they told us.

10. AirSage Environmental Equipment

Founded: 2009 | Headquarters: Xi’an | Key Focus: Low-maintenance, long-lasting systems

Last but not least, AirSage is for recyclers who hate downtime. Their systems are built with heavy-duty components—stainless steel scrubbers, ceramic-lined ductwork, and industrial-grade fans—that require minimal upkeep. Their “ToughGuard LiB” has a filter replacement cycle of 6–8 months, compared to the industry average of 3–4 months.

AirSage also offers a unique “Remote Monitor” service, where their engineers track your system’s performance 24/7 and alert you to potential issues before they cause problems. A recycler in Gansu with limited on-site maintenance staff said, “AirSage’s system runs like a workhorse. We barely think about it—and that’s exactly what we need.”
