Top 10 Air Pollution Control System Suppliers in South Korea

Founded in 1998, Korea EcoTech Solutions has grown from a small local firm to a global leader, with installations in over 40 countries. What really put them on the map? Their custom air pollution control systems for battery recycling facilities , particularly lead acid and lithium battery plants. Unlike one-size-fits-all solutions, EcoTech starts by analyzing your specific process—whether you’re handling lead paste reduction or lithium battery breaking—and designs a system that targets the unique pollutants generated, from sulfur oxides to fine particulate matter.

Take their work with a major European lithium battery recycler, for example. The client needed to process 1,500 kg/h of battery cells, which release volatile organic compounds (VOCs) and metal particulates during shredding. EcoTech installed a multi-stage system: first, a high-efficiency cyclone to capture large particles, followed by a wet scrubber for acid gases, and a final activated carbon filter for VOCs. The result? Emissions reduced by 98% compared to the client’s previous setup, and compliance with the EU’s strict REACH regulations.

Beyond batteries, they’re also a top choice for circuit board recycling equipment manufacturers, offering compact, modular systems that fit into tight factory spaces. Clients often praise their after-sales support—with a 24/7 technical hotline and local service centers in key markets like the U.S., Germany, and China.

Seoul Air Control Systems, or SACS, is a name you’ll hear often in industrial circles, and for good reason: they pioneered the use of nanoceramic filters in air pollution control , a technology that’s become a game-changer for high-temperature processes like metal melting furnaces and lead refinery operations. Traditional filters can clog or degrade quickly in extreme heat, but SACS’s nano-ceramic composite filters withstand temperatures up to 800°C, reducing maintenance costs by up to 40% for clients.

One of their standout products is the “CleanAir Pro Series,” designed specifically for lead acid battery recycling equipment. These systems combine a baghouse filter with a thermal oxidizer to tackle both particulate matter and toxic gases like hydrogen sulfide. A recent project in Southeast Asia saw SACS equip a lead battery breaking and separation plant with a CleanAir Pro system, allowing the facility to process 2,000 kg/h of batteries while keeping emissions well below local limits. The client reported a 30% ｄｒｏｐ in energy use compared to their old system, thanks to SACS’s energy-recovery heat exchangers.

SACS isn’t just about heavy industry, though. They’ve also made strides in smaller-scale solutions, like portable air pollution control units for workshops and small recycling facilities. Their “MiniClean” line, launched in 2021, has been a hit with scrap metal recyclers and cable stripping operations, offering easy installation and low power consumption.

Daegu Environmental Technologies has built its reputation on innovation in odor and VOC control , making them a favorite for facilities where air quality isn’t just about compliance, but also worker comfort. Their signature product, the “OdorGuard” system, uses a combination of UV photolysis and biofiltration to neutralize smells and harmful organic compounds—a must for recycling plants handling plastics, refrigerants, or e-waste.

A case in point: a major refrigerator recycling plant in Australia was struggling with strong odors from refrigerant extraction and plastic shredding. Daegu installed an OdorGuard system that not only eliminated 95% of the unpleasant smells but also reduced VOC emissions by 90%, leading to better working conditions and fewer complaints from nearby communities. The system was so effective that the client expanded it to their air conditioning recycling line the following year.

Daegu also excels in integrating air pollution control with water treatment systems, a critical need for wet-process recycling operations. For a circuit board recycling plant in Japan using a wet separation process, they designed a closed-loop system that captures air pollutants, treats the wastewater, and recycles both air and water back into the process—cutting the facility’s water usage by 45% and ensuring zero harmful discharge.

Incheon Air Systems is all about scalability , and that’s why they’re the first choice for growing recycling operations. Whether you’re a startup processing 500 kg/h of lithium batteries or a multinational with a 2,500 kg/h circuit board recycling plant, Incheon’s modular systems can grow with you, saving you the cost of replacing equipment as your capacity increases.

Take their “ModuAir” series: each unit is designed to work independently or be linked together, so a client starting with one module can add more as demand grows. A European cable recycling company recently used this approach, starting with a single ModuAir unit for their scrap cable stripper line and adding two more modules within two years as they expanded into copper wire recycling. The best part? The expansion took just three days, with minimal downtime.

Incheon also specializes in air pollution control for metal melting furnaces, including medium-frequency induction furnaces common in lead and aluminum recycling. Their “MeltClean” system uses high-velocity capture hoods positioned strategically around the furnace to trap fumes at the source, reducing the need for large, energy-intensive exhaust systems. Clients report up to 35% lower energy bills compared to traditional hood designs.

Busan GreenTech may be the youngest company on this list (founded in 2010), but they’ve quickly made a name for themselves with AI-driven air pollution control systems that adapt in real time to changing process conditions. Their “SmartAir” platform uses sensors and machine learning to adjust fan speeds, filter cleaning cycles, and chemical injection rates based on actual emissions data—ensuring optimal performance while minimizing energy and chemical use.

A lithium battery recycling plant in Canada is a great example: their SmartAir system monitors particulate levels, temperature, and gas concentrations every 10 seconds. When the plant switches from processing lithium cobalt oxide batteries to lithium iron phosphate (which emits different pollutants), the system automatically adjusts the scrubber chemistry and filter airflow, maintaining compliance without manual intervention. The plant manager noted, “We used to have to shut down for 2–3 hours when switching battery types to reconfigure the pollution control system. Now it’s seamless.”

Busan GreenTech also offers turnkey solutions for small to medium-sized facilities, including financing options and lease-to-own programs, making their advanced technology accessible to businesses with limited upfront capital. Their focus on customer education—including free online training webinars and on-site workshops—has earned them high marks for client satisfaction.

Gwangju Environmental Engineering has a niche but vital specialty: air pollution control for hazardous waste recycling , including CRTs, lamps, and batteries containing heavy metals. These materials release some of the most toxic pollutants—like lead, mercury, and cadmium—making robust control systems non-negotiable.

Their “HazardGuard” system is a favorite among lamp recycling facilities. Equipped with specialized mercury-capture filters and a cryogenic condensation unit, it can remove over 99.9% of mercury vapor from lamp breaking operations. A U.S.-based bulb recycling plant using HazardGuard reports that their mercury emissions are now so low they’ve been able to market their recycled glass as “mercury-free,” opening up new revenue streams in construction and consumer goods.

Gwangju also partners closely with lead acid battery recycling equipment manufacturers to design integrated systems for de-sulfurization units and paste reduction furnaces. For a lead refinery in India, they installed a dual-stage system: first, a dry electrostatic precipitator to capture lead particulates, followed by a wet scrubber for sulfur dioxide. The result? The refinery now meets India’s stringent BS-VI emissions standards and has reduced its lead waste disposal costs by 60% by recovering and reusing the captured lead dust.

Daejeon Air Innovations prides itself on energy efficiency , and their systems are consistently ranked among the lowest in power consumption in independent tests. Their secret? A focus on aerodynamics and variable-speed drive technology that ensures fans and blowers only use as much energy as needed, rather than running at full tilt 24/7.

For a lithium ore extraction plant in Chile, Daejeon designed an air pollution control system that uses just 1.2 kW per ton of ore processed—30% less than the industry average. The system combines a low-pressure, high-volume fan with a fabric filter that’s cleaned using compressed air pulses only when pressure ｄｒｏｐ reaches a certain threshold, further saving energy. The client estimates the energy savings alone will pay for the system in under three years.

Daejeon also leads in compact design, a boon for urban recycling facilities where space is at a premium. Their “SlimLine” series of air pollution control units are 40% smaller than comparable systems, allowing them to fit into tight corners or even be mounted on rooftops. A circuit board recycling plant in Seoul, squeezed into a former warehouse, used SlimLine units to meet emissions standards without expanding their facility—a move that saved them millions in relocation costs.

Ulsan Clean Energy Systems is unique in that they combine air pollution control with energy recovery , turning a necessary expense into a revenue-generating asset for their clients. Their “EcoRecover” systems capture heat from industrial exhaust streams and convert it into usable energy—whether for heating, electricity, or process steam.

A metal melting furnace operator in Turkey is a prime example: Ulsan installed an EcoRecover system that captures heat from the furnace’s exhaust (which can reach 1,200°C) and uses it to preheat the incoming scrap metal. This reduced the furnace’s natural gas consumption by 25%, saving the client over $200,000 annually. The system also includes a baghouse filter to capture metal particulates, which are sold back to foundries as raw material—adding another revenue stream.

Ulsan is also a leader in air pollution control for the automotive recycling sector, particularly for motor stator cutting and shredding operations. Their systems are designed to handle the mixed pollutants from metal, plastic, and insulation, with replaceable filter media tailored to specific materials. A car battery recycling plant in Germany using Ulsan’s system reports that their emissions are now so low they’ve been granted “green factory” status by local authorities, qualifying them for tax incentives.

Suwon Environmental Systems has built its brand on reliability in harsh environments , making them a top pick for facilities in extreme climates or remote locations. Their systems are tested to withstand everything from desert heat (up to 55°C ambient temperature) to Arctic cold (-30°C), and their rugged construction means minimal maintenance in dusty or humid conditions.

A lithium tailing ore extraction plant in Mongolia faced two big challenges: extreme cold and high dust levels from ore crushing. Suwon delivered a system with heated filter housings to prevent freezing, and a heavy-duty dust collection system with reinforced ducting to handle abrasive particles. Even in -25°C winters, the system operates 24/7 with only monthly inspections, a far cry from the weekly breakdowns the plant experienced with its previous equipment.

Suwon also specializes in mobile air pollution control units, ideal for construction sites, temporary recycling operations, or disaster cleanup. Their “MobileGuard” units are mounted on trailers, can be set up in under an hour, and run on either diesel generators or grid power. A disaster response team in the Philippines used MobileGuard units after a typhoon to control dust and fumes from debris recycling, helping to prevent secondary environmental contamination.

Rounding out our list is Jeju Eco Solutions, a company that’s making waves with sustainable materials and circular design in their air pollution control systems. While most suppliers focus on controlling emissions, Jeju takes it a step further by ensuring their own equipment is as eco-friendly as possible—using recycled materials, modular components for easy repair, and systems that can be repurposed or recycled at the end of their life.

Their “GreenBuild” line of filters, for example, uses recycled aluminum frames and filter media made from post-consumer plastic bottles. For a plastic pneumatic conveying system manufacturer in Europe, Jeju supplied GreenBuild filters that not only reduced emissions but also helped the client meet their sustainability goals for product sourcing. The client’s customers, in turn, have praised the move, leading to a 15% increase in orders for the conveying systems.

Jeju also offers a unique “Lease-a-System” program, where clients pay a monthly fee that includes maintenance, filter replacements, and eventual system upgrades. At the end of the lease, Jeju takes back the old system, refurbishes it, and re-leases it—keeping equipment out of landfills. A small circuit board recycling startup in Brazil used this program to get off the ground without a large upfront investment, and now that they’re profitable, they’re upgrading to a larger Jeju system with the same circular model.
