Key specs include a (processing capacity) of 5,000 cubic meters per hour (m³/h), making it suitable for mid-to-large lead acid battery recycling plants. It also features a smart control panel with real-time emissions monitoring, so you can track pollutant levels and adjust settings on the fly. Energy efficiency is another win here: the variable-speed blower reduces power consumption by up to 20% compared to fixed-speed models, which adds up to significant savings over time.

Best For: Lead acid battery recycling facilities with daily processing capacities of 500kg to 2,000kg. Its robust sulfur dioxide scrubbing makes it ideal for operations using processes like paste reduction melting or lead refinery furnaces.

Pros: Excellent lead and SO₂ removal efficiency (99.9% for particulates, 95% for SO₂); smart monitoring for compliance peace of mind; energy-efficient design.
Cons: On the larger side (requires ~30m² of floor space); higher upfront cost than compact models.

Lithium-ion battery recycling comes with its own set of air pollution challenges—think volatile organic compounds (VOCs) from electrolyte breakdown and fine metal oxide particulates (like lithium, cobalt, and nickel). The LiClear VOC-Master is purpose-built to tackle these, making it a top pick for li battery recycling equipment setups.

At its core is a catalytic oxidation unit that breaks down VOCs at high temperatures (around 700°C), converting them into harmless CO₂ and water. Paired with a pre-filter and a ceramic filter for metal oxides, it ensures emissions are well below regulatory limits. What really impresses, though, is its adaptability: the system can handle variable VOC loads, which is crucial in lithium battery recycling where processing volumes might fluctuate.

With a capacity of 3,000–6,000 m³/h, it's scalable for both small (500kg/h) and large (2,500kg/h) lithium battery recycling plants. It also includes a heat recovery system that redirects excess heat to warm the facility or preheat incoming air, cutting down on auxiliary heating costs.

Best For: Lithium-ion battery breaking and separating operations, especially those using dry processes or compact granulators with dry separators. It's also a solid fit for facilities handling cathode materials, where VOC emissions are highest.

Pros: Industry-leading VOC destruction efficiency (99%+); heat recovery for energy savings; handles variable loads without performance drops.
Cons: Requires periodic catalyst replacement (every 2–3 years); higher initial investment than basic filtration systems.

Not every operation needs a massive industrial system. If you run a small recycling facility—say, a scrap cable stripping shop or a compact circuit board recycling plant with a capacity of 300–500kg/h—the CompactClean Mini-300 is a practical, budget-friendly choice. Don't let its size fool you: this compact unit (just 10m² of floor space) packs a punch with a two-stage filtration system.

First, a high-powered fan draws in polluted air, passing it through a cartridge filter that traps dust and small particulates (like copper from cable recycling or glass fibers from circuit boards). Then, an activated carbon filter adsorbs odors and light VOCs, leaving the air clean and fresh. It's simple to install, with plug-and-play functionality, and requires minimal maintenance—just swap out the filters every 3–6 months, depending on usage.

With a capacity of 300 m³/h, it's not meant for heavy-duty use, but for small shops or startups, it's a cost-effective way to stay compliant without breaking the bank. The digital display shows filter status, so you'll never be caught off guard by a clogged filter.

Best For: Small-scale recycling operations like scrap cable strippers, compact circuit board recycling plants (300–500kg/h), or lamp recycling facilities. It's also a great backup system for larger plants during maintenance shutdowns.

Cons: Limited capacity (not for high-volume operations); no scrubbing for acidic gases like SO₂.

For facilities that handle multiple recycling streams—think a plant that processes both lead acid batteries and circuit boards—the UltraPure APC-8000 is the ultimate multitasker. This system combines the best of particulate filtration, gas scrubbing, and VOC control into a single, integrated unit. It's like having three systems in one, which saves space and simplifies operations.

The workflow is seamless: Polluted air first enters a venturi scrubber to remove large particulates and acidic gases (like SO₂ from lead recycling or HCl from circuit board etching). Then, a baghouse filter captures fine dust (down to 1 micron), followed by a catalytic oxidizer for VOCs. Finally, a carbon bed polishes the air, ensuring no odors or residual pollutants escape.

With a (capacity) of 8,000 m³/h, it's built for large-scale facilities with diverse needs. The system also includes a modular design, so you can add or remove components based on your current recycling focus—swap out the catalytic oxidizer for an extra scrubber if you shift from lithium to lead recycling, for example.

Best For: Multi-stream recycling plants handling lead acid batteries, circuit boards, and/or scrap cables. It's also a strong choice for facilities planning to expand into new recycling areas in the future.

Pros: Handles multiple pollutants (particulates, acids, VOCs); modular design for flexibility; high capacity (8,000 m³/h).
Cons: High upfront cost (starting at $150,000); requires professional installation and training.

If you're running a small lithium battery recycling plant (500–1,000kg/h) and energy efficiency is a top priority, the GreenGuard 2000 deserves a spot on your shortlist. This model redefines "green" with a design that slashes energy use by up to 35% compared to standard systems—without skimping on performance.

How does it do it? A rotary concentrator that reduces the volume of air needing VOC treatment by up to 90%. Instead of processing all 2,000 m³/h of air, the concentrator captures VOCs and feeds a smaller stream (200 m³/h) into a compact catalytic oxidizer. This means the oxidizer uses less fuel and electricity, cutting both energy bills and carbon footprint. For particulates, a high-efficiency pleated filter captures lithium and metal oxides, with a self-cleaning mechanism that extends filter life.

The GreenGuard 2000 also includes a user-friendly touchscreen interface with pre-programmed settings for common lithium recycling processes (like battery breaking, shredding, or electrode separation), making it easy to set up and operate—even for teams new to air pollution control.

Best For: Small to mid-sized lithium-ion battery recycling plants focused on sustainability and energy savings. It's particularly well-suited for dry process operations, where VOCs are more concentrated.

Cons: Lower capacity (2,000 m³/h); not ideal for high-VOC loads above 5,000 ppm.

Scrap metal recycling—whether it's cable stripping, motor stator cutting, or metal melting—generates a lot of dust: iron filings, copper particles, aluminum shavings, and more. The DustBuster Pro-X is engineered to tackle these particulates head-on, with a focus on speed and efficiency.

The star feature here is a reverse-pulse jet baghouse with 120 filter bags made from heat-resistant polyester. This design allows for continuous operation: while some bags are cleaned (via compressed air pulses), others keep filtering, so there's no need to shut down for maintenance. It captures particulates as small as 0.5 microns with 99.9% efficiency, which is critical for compliance and worker health.

With a (airflow) of 6,000 m³/h, it's ideal for high-speed operations like cable recycling lines with hydraulic cutters or motor recycling machines. It also includes a heavy-duty steel frame and corrosion-resistant components, so it holds up in harsh industrial environments.

Best For: Scrap metal recycling facilities, including cable strippers, motor stator cutters, and metal melting furnaces. It's also a solid choice for circuit board recycling plants using dry separation, where fiberglass and metal dust are common.

Pros: Continuous operation (no downtime for cleaning); durable build for tough environments; high particulate capture efficiency.
Cons: Not designed for gas or VOC removal; requires regular filter bag replacement (every 6–12 months).

For large-scale lithium battery recycling plants (processing 2,000kg/h or more), VOC emissions can be off the charts—especially during battery breaking, shredding, and electrode processing. The CleanAir RTO-4000 (Regenerative Thermal Oxidizer) is built to handle these high loads, using a design that recovers up to 95% of the heat generated during VOC destruction to reduce fuel costs.

Here's how it works: Polluted air enters a chamber filled with ceramic heat exchange media, which preheats the air to 800°C using heat from previous cycles. At this temperature, VOCs oxidize into CO₂ and water. The heated air then passes through another heat exchange chamber, transferring its heat to the media for the next cycle. This regenerative process makes the RTO-4000 incredibly fuel-efficient, even for high VOC concentrations (up to 5,000 ppm).

With a capacity of 4,000–10,000 m³/h, it's scalable to match your plant's growth. It also includes a redundant design with backup burners and sensors, ensuring it stays operational even if one component fails—a must for facilities with tight production schedules.

Best For: Large lithium-ion battery recycling plants with high VOC emissions, such as those processing 2,000kg/h or more of li-ion batteries. It's also ideal for facilities using solvent-based processes in battery component recovery.

Pros: 99%+ VOC destruction efficiency; ultra-high heat recovery (95%); scalable for growth.
Cons: Large footprint (requires ~50m²); high installation cost (best for high-volume operations to justify investment).

Circuit board recycling often involves wet processes like acid leaching to recover metals like gold, silver, and copper. These processes release harmful acid gases—think hydrochloric acid (HCl), nitric acid (HNO₃), and hydrofluoric acid (HF)—which require specialized scrubbing to neutralize. Enter the ScrubMax AcidGuard, a system built specifically to tackle these corrosive gases.

The AcidGuard uses a two-stage wet scrubbing process : first, a venturi scrubber with high-velocity water jets to atomize and capture acid gas droplets, then a packed tower with alkaline solution (like sodium hydroxide) to neutralize remaining acids. The result? 99% removal efficiency for HCl and 98% for HF, ensuring emissions are well below regulatory limits.

It also includes a closed-loop water recycling system that treats and reuses scrubbing water, reducing water waste by up to 80%—a big plus for facilities in water-scarce regions. The system is constructed with corrosion-resistant materials (PVC, polypropylene, and Teflon), so it stands up to the harsh acids it's designed to neutralize.

Best For: Circuit board recycling plants using wet processes (acid leaching, etching) or facilities handling other acid-generating materials like CRT glass or battery electrolytes.

Pros: Superior acid gas removal; water recycling for sustainability; corrosion-resistant construction.
Cons: Requires regular chemical replenishment (alkaline solution); not effective for VOCs or non-acidic particulates.

Not all recycling happens in fixed facilities. If you run a mobile operation—like on-site cable stripping, small-scale lamp recycling, or temporary battery collection points—you need a portable air pollution control solution. The AirPure Mobile-300 fits the bill, with a compact, wheeled design that can be moved with a forklift or truck.

Despite its size (just 2m x 1.5m x 2m), it packs a surprising punch: a HEPA filter for particulates (99.97% efficiency at 0.3 microns) and an activated carbon filter for odors and light VOCs. It runs on a 220V power supply (no need for three-phase electricity) and has a built-in fan with adjustable speed, so you can match airflow to your needs (up to 300 m³/h).

The Mobile-300 is also easy to set up: simply wheel it into place, connect the inlet hose to your recycling equipment (like a portable cable stripper or lamp crusher), and plug it in. It's lightweight enough for transport but sturdy enough to handle the bumps of on-site work, with a steel frame and weather-resistant covers for outdoor use.

Best For: Mobile recycling operations, small workshops, or temporary facilities. It's perfect for lamp recycling (capturing mercury vapor), scrap cable stripping, or small-scale battery breaking.

Pros: Fully portable; easy to set up and operate; no permanent installation required.
Cons: Low capacity (300 m³/h); limited to particulates and light VOCs; filters need frequent replacement in high-dust environments.

For facilities that want to stay ahead of the curve, the SmartAir APC-9000 brings artificial intelligence (AI) to air pollution control. This system doesn't just filter pollutants—it learns from your operations to optimize performance, predict maintenance needs, and ensure 24/7 compliance.

At its core is a machine learning algorithm that analyzes data from 15+ sensors (emissions levels, filter pressure, energy use, temperature) to identify patterns. For example, if it notices higher lead dust levels during morning shifts, it'll automatically adjust the fan speed and filter cleaning frequency to maintain efficiency. It also sends alerts to your phone or computer when filters are nearing the end of their life or when emissions start to creep above safe levels—so you can address issues before they become compliance problems.

The filtration system itself is top-tier: a combination of cyclone, HEPA, chemical scrubber, and catalytic oxidizer to handle particulates, acids, and VOCs. With a capacity of 9,000 m³/h, it's built for large, complex recycling plants handling multiple materials (lead, lithium, circuit boards, etc.). The AI platform also integrates with your facility's management software, providing detailed reports on emissions, energy use, and maintenance history—perfect for audits or sustainability reporting.
