Top 5 Air Pollution Control System Suppliers in South Korea [2025]

Company Overview

When you hear “Hyundai,” you probably think of cars—but their environmental tech arm has been quietly leading the pack since 1995. Headquartered in Seoul, Hyundai Environmental Tech cut its teeth building pollution control systems for the automotive industry (no surprise there) before expanding to chemicals, textiles, and even waste incineration plants. Today, they’re trusted by 80% of South Korea’s top 50 manufacturing companies, and for good reason: their equipment is built to last, even in the toughest industrial environments.

Star Products: Air Pollution Control System & Filter Press Equipment

Their flagship air pollution control system equipment is a beast. We’re talking modular units that can be scaled from 5,000 to 500,000 cubic meters of air per hour—perfect for everything from a small welding shop to a massive steel mill. What really sets it apart? The multi-stage filtration: first, a pre-filter catches large dust particles, then a HEPA filter traps fine particulates, and finally, a chemical scrubber neutralizes toxic gases like sulfur dioxide. It’s like a triple-layered defense for the air.

Then there’s their filter press equipment —the unsung hero of waste management. This gear dewatering sludge from industrial processes, turning messy slurry into dry cake that’s easy to dispose of or recycle. For example, a Hyundai filter press installed at a Busan chemical plant reduced sludge disposal costs by 40% in just six months. The secret? Automated plate shifting that speeds up the filtration cycle and a self-cleaning mechanism that cuts down on downtime.

Why They Stand Out

Durability is their middle name. Take the case of Hyundai Steel’s Incheon plant: they installed a Hyundai APCS in 2010, and it’s still running at 95% efficiency today—15 years later. Plus, their systems are designed to meet not just Korean regulations but also EU and U.S. standards, which is a big deal if you’re exporting products (no one wants to get blocked by a “dirty factory” label). And with a 24/7 technical support hotline and 100+ service centers across Asia, you’re never left hanging if something needs tweaking.

Company Overview

Samsung isn’t just about phones and TVs—their engineering division, founded in 2002, is on a mission to make环保 tech smarter. Based in Incheon, they’ve leveraged Samsung’s expertise in AI and IoT to create air pollution control systems that don’t just work—they think . Their clients range from semiconductor giants (hello, Samsung Electronics) to pharmaceutical labs, where precision and cleanliness are non-negotiable.

Star Products: Smart APCS & Dry Process Equipment

Imagine an air pollution control system that texts you when it needs maintenance. That’s Samsung’s Smart APCS in a nutshell. It uses sensors to monitor pollutant levels, energy use, and filter health in real time, then sends alerts to your phone or laptop. At a Seoul semiconductor plant, this feature caught a clogged filter before it caused a production slowdown—saving an estimated $100,000 in downtime. The system even learns from patterns, adjusting fan speeds and chemical dosages automatically to optimize efficiency. It’s like having a 24/7 air quality manager who never sleeps.

For facilities that want to avoid water waste, their dry process equipment is a game-changer. Instead of using water to scrub pollutants, it uses electrostatic precipitation: think of tiny charged plates that attract dust particles like a magnet. A Samsung dry process system installed at a semiconductor cleanroom reduced water usage by 100% (yes, zero water!) while maintaining 99.9% particle removal efficiency. Perfect for drought-prone areas or water-strapped industries.

Why They Stand Out

Innovation, plain and simple. Samsung’s R&D team files an average of 20 patents a year in air pollution control alone. Their latest breakthrough? A machine learning algorithm that predicts emissions spikes based on production schedules, allowing the system to ramp up filtration before pollutants even hit the air. And let’s not forget integration: their APCS syncs seamlessly with Samsung’s Smart Factory software, giving plant managers a single dashboard for all operations. It’s tech that works with your workflow, not against it.

Company Overview

LG Eco Systems, a subsidiary of LG Chem, burst onto the scene in 2010 with a clear goal: make环保 tech accessible to small and medium-sized businesses (SMBs). While other suppliers focus on mega-plants, LG zeroed in on the 90% of Korean factories that operate out of tight spaces with limited budgets. Today, they’re the go-to for workshops, food processing facilities, and small chemical labs across the country.

Star Products: Wet Process Equipment & Compact APCS

Their wet process equipment is a masterclass in efficiency. Traditional wet scrubbers use tons of water to dissolve pollutants, but LG’s design recycles 80% of the water, slashing costs and waste. A bakery in Daegu that installed one of their units to control flour dust and oven emissions now uses just 500 liters of water a day—down from 2,000 liters with their old system. The scrubber also doubles as a deodorizer, neutralizing that “burnt bread” smell that used to annoy neighbors. Win-win.

Then there’s their compact APCS —the “apartment-friendly” option. Measuring just 1.5m x 1.5m x 2m, it’s small enough to fit in a corner but powerful enough to clean 10,000 cubic meters of air per hour. A Seoul-based electronics repair shopswears by it: “We used to have to close windows to keep dust out, but now we can keep them open, and our techs say they breathe easier,” the owner told us. It’s quiet too—around 65 decibels, about as loud as a normal conversation—so it doesn’t disrupt workflow.

Why They Stand Out

LG gets that SMBs can’t afford fancy engineers or complicated maintenance. That’s why their equipment is plug-and-play: unbox, connect to power and ductwork, and start cleaning air in 30 minutes. They also offer flexible financing—leases starting at $500/month—so you don’t have to ｄｒｏｐ a fortune upfront. And their customer service? A small business owner in Busan called at 7 PM with a broken filter, and a technician was on-site by 9 AM the next day. That’s the kind of support that makes a difference.

Company Overview

Daewoo has been around since 1988, and they know heavy industry like the back of their hand. Based in釜山, they’ve built systems for power plants, oil refineries, and shipyards—places where temperatures soar, dust is everywhere, and emissions are off the charts. If your factory deals with high heat, corrosive gases, or massive air volumes, Daewoo is the name to know.

Star Products: High-Capacity APCS & Wet/Dry Hybrid Systems

Their high-capacity APCS is a monster for power plants. A single unit can handle 1 million cubic meters of air per hour—enough to clean the air in a football stadium in 10 minutes. At a coal-fired power plant in Pohang, their system reduced particulate emissions by 98% and sulfur dioxide by 95%, helping the plant meet Korea’s strict 2023 emissions standards. The secret? A regenerative thermal oxidizer that burns off VOCs at 800°C, leaving only water vapor and CO2.

For industries that need flexibility, their wet & dry process equipment hybrid is genius. It switches between wet scrubbing (for gases) and dry electrostatic precipitation (for dust) depending on what’s in the air. A chemical plant in Ulsan uses it to handle both acid mist (wet process) and catalyst dust (dry process) from the same exhaust stream. The result? 30% lower energy costs than running two separate systems.

Why They Stand Out

They build for the long haul. Daewoo systems are rated to last 20+ years, even in high-temperature, high-corrosion environments. Their secret? Heavy-duty materials like Hastelloy alloy for scrubber tanks and ceramic coatings for heat exchangers. Plus, they offer a “Lifetime Performance Guarantee”: if their system doesn’t meet emissions targets within the first 10 years, they’ll upgrade it for free. That’s confidence you can bank on.

Company Overview

The new kid on the block (founded 2015), SK Clean Technology is shaking things up with nanotechnology. A spin-off from SK Group’s materials science division, they’re all about using tiny particles to solve big pollution problems. Based in大田, they’ve quickly made a name for themselves in high-tech industries like semiconductors, solar panels, and lithium battery manufacturing—where even the smallest pollutant can ruin a product.

Star Products: Nano-Ceramic Filter APCS & Portable Units

Their nano-ceramic filter APCS is straight out of a sci-fi movie. The filters are coated with nano ceramic ball particles—each smaller than a red blood cell—that trap pollutants at the molecular level. For example, a semiconductor plant in Gyeonggi Province uses these filters to remove 99.99% of sub-micron particles (that’s particles smaller than 0.1 microns!), which is critical for making microchips with 5nm technology. The filters also last 3x longer than traditional ones because the ceramic resists clogging.

Need something you can move around? Their portable APCS units are a lifesaver for construction sites, temporary factories, or emergency spill cleanups. Weighing just 500kg and mounted on wheels, they can be towed by a pickup truck and set up in 2 hours. A disaster response team used one after an oil refinery fire in Yeosu in 2024, cleaning 5,000 cubic meters of smoke-filled air per hour until permanent systems were restored.

Why They Stand Out

Innovation is in their DNA. SK’s R&D team works with Seoul National University to develop new nano-materials, and they just launched a filter coated with nano composite ceramic ball particles that can break down VOCs into harmless CO2 and water using sunlight—no electricity needed. For green-minded companies, that’s a huge selling point. Plus, their systems are incredibly energy-efficient: a nano-ceramic APCS uses 25% less power than a conventional one, which adds up to big savings over time.
