Top 10 Filter Press Suppliers in the United States in 2025

American Filtration Technologies isn’t just a supplier—they’re a pioneer. Since 1985, AFT has been perfecting the art of separating solids and liquids, and their filter press equipment has become a staple in recycling plants across the country. What sets them apart? Their ability to tailor solutions to niche industries, especially in lead acid battery recycling .

Take their flagship Model 5000 Filter Press, for example. Designed specifically for battery recycling facilities, it handles the thick, corrosive sludge from lead paste separation with ease. “We used to spend hours cleaning out old presses every week,” says Mark, a plant manager at a Midwest battery recycling facility. “AFT’s system has cut that time by 70%—and the filtrate is so clean, we can reuse it in our water process equipment . It’s been a game-changer for our bottom line.”

AFT doesn’t stop at standard models, either. Their engineering team works closely with clients to build custom presses for unique challenges, like the high-temperature environments of metal melting furnace operations. And with a nationwide network of service technicians, downtime is rarely an issue. “When we had a sensor fail last winter, AFT had a tech on-site within 24 hours,” Mark adds. “You can’t put a price on that kind of reliability.”

If “green technology” is your priority, EcoPress Solutions should be at the top of your list. This Portland-based company built its reputation on creating filter presses that slash energy use without sacrificing performance. Their ECO-3000 series, for instance, uses 30% less electricity than traditional models—no small feat for a machine that runs 24/7 in busy recycling plants.

EcoPress has also made waves in the circuit board recycling sector. Their compact filter presses are designed to fit into tight spaces, making them ideal for facilities processing e-waste. “Circuit board recycling generates a lot of fine particles, and traditional presses struggle with clogging,” explains Sarah, an environmental engineer who consulted on a California e-waste plant. “EcoPress’s self-cleaning membrane technology keeps the screens clear, so we can process up to 1,500 kg/hour without stopping. And because it’s energy-efficient, we qualify for state green energy rebates—win-win.”

Beyond the tech, EcoPress prides itself on transparency. They publish third-party energy efficiency reports for all models and offer free sustainability audits to help clients optimize their processes. “They don’t just sell you a press—they help you make your entire operation greener,” Sarah notes. For companies aiming to hit net-zero goals, that’s invaluable.

When the going gets tough, Industrial Press Masters’ machines keep going. Specializing in heavy-duty filter presses for high-pressure applications, IPM has become the go-to for mining operations and metal melting furnace facilities. Their HDX Series can handle pressures up to 3,000 psi, making it perfect for dewatering dense slurries from lithium ore extraction or tailing ore processing.

“We work with some of the thickest sludges in the industry—think wet concrete consistency,” says Jake, a plant engineer at a Nevada lithium mine. “IPM’s HDX-4500 doesn’t flinch. It squeezes out so much water that our waste disposal costs have dropped by 40%. And the build quality? We’ve had ours for five years, and it still runs like new—even with daily use.”

IPM also excels in integration. Their presses sync seamlessly with hydraulic press machines and automated conveying systems, reducing the need for manual labor. For large-scale operations, this translates to faster processing times and fewer errors. “We recently upgraded to their automated control system,” Jake adds. “Now, one operator can monitor three presses from a tablet. It’s cut our staffing needs on the night shift by half.”

CleanWater Systems may be the new kid on the block, but they’ve quickly made a name for themselves with their user-friendly, low-maintenance filter presses. Founded by a team of wastewater engineers frustrated with outdated equipment, the company focuses on simplicity without cutting corners.

Their most popular model, the CW-200, is a hit with small to mid-sized recycling plants, especially those handling wet process equipment runoff. “We’re a family-owned cable recycling shop—we don’t have a big tech team,” says Lisa, who runs a facility in Colorado. “CleanWater’s press is so easy to use, my nephew (who’s still in high school!) can operate it after 10 minutes of training. And when we do have questions, their support team answers the phone in 5 minutes—no automated menus, just real people.”

CleanWater also offers a unique rental program, perfect for businesses testing new recycling lines or dealing with seasonal demand. “We rented a CW-200 for three months to see if it could handle our scrap cable stripper wastewater,” Lisa explains. “It worked so well, we bought it outright. The rental fee even went toward the purchase—how cool is that?”

When you need to process tons of material daily, National Press Systems has your back. With over 45 years in the game, NPS specializes in high-capacity filter presses that can handle 5,000+ gallons of slurry per hour—ideal for mega-facilities like refrigerator & AC recycling plants or automotive shredder operations.

Their NPS-10000 model is a beast, but it’s surprisingly efficient. “We process over 200 tons of refrigerators a day,” says Raj, operations director at a Georgia recycling hub. “The foam and refrigerant sludge used to overwhelm our old presses, leading to bottlenecks. NPS’s system processes it all in half the time, and the cake is so dry, we can sell it as fuel for cement kilns. That’s turned a waste product into revenue—about $50k a year, to be exact.”

NPS also leads in automation. Their SmartPress software integrates with plant management systems, allowing real-time monitoring of pressure, flow rates, and cake moisture. “I can check press performance from my phone at 2 a.m.,” Raj laughs. “Not that I need to—downtime is less than 1% a month. These machines are workhorses.”

Precision Filtration Works lives up to its name. This Detroit-based supplier caters to industries where accuracy is non-negotiable, like lithium battery recycling and circuit board processing. Their microfiltration presses can separate particles as small as 0.1 microns—critical for recovering valuable metals from e-waste.

“In lithium battery recycling, even tiny impurities can ruin the recovered materials,” says Dr. Kim, a materials scientist at a California tech firm. “PFW’s PFX-5000 uses a patented ceramic membrane that traps 99.9% of contaminants. We’ve been able to increase our lithium recovery rate by 15% since switching to their press—enough to make our recycling line profitable after just six months.”

PFW also invests heavily in R&D, releasing new models every 2–3 years. Their latest innovation? A press with built-in air pollution control system integration, reducing fugitive emissions during filtration. “It’s the little details,” Dr. Kim adds. “Like how the press automatically alerts us when filters need changing, or how the stainless-steel frame resists corrosion from battery acids. PFW thinks of everything.”

Western States Press knows heat. Based in Phoenix, where summer temperatures regularly hit 110°F, the company designs filter presses that thrive in extreme environments—making them a top choice for metal melting furnace operators and lithium ore extraction plants in the Southwest.

Their HeatShield Series uses specialized seals and cooling jackets to prevent overheating, even when processing slurry at 200°F. “We run a medium frequency electricity furnace for aluminum recycling,” says Tom, a plant manager in Arizona. “Old presses would seize up in the summer heat, costing us $10k a day in downtime. WSP’s HeatShield press hasn’t missed a beat in three years—even during our monsoon season, when humidity spikes. It’s like they built it to survive a desert apocalypse.”

WSP also offers free on-site consultations, sending engineers to assess your facility’s unique conditions. “They measured our ambient temperature, humidity, and even the vibration from nearby furnaces before recommending a model,” Tom recalls. “That level of attention is why we’ve stuck with them.”

Northeast Filter Corp doesn’t believe in “one-size-fits-all.” For 40 years, this Boston-based supplier has built custom filter presses for the trickiest recycling challenges—from CRT recycling machines to lamp recycling equipment .

Their most ambitious project to date? A filter press for a bulb eater manufacturer, designed to separate mercury-laden sludge from broken fluorescent bulbs. “Mercury is highly toxic, so the press needed zero leakage and airtight containment,” explains Elena, an environmental compliance officer who oversaw the project. “NEFC spent six months testing prototypes, even building a mock plant in their warehouse to simulate our process. The final system is so safe, our OSHA inspector called it ‘flawless.’”

NEFC’s custom work doesn’t come cheap, but clients say it’s worth every penny. “You pay for expertise,” Elena notes. “When you’re dealing with hazardous materials, cutting corners on filtration isn’t an option. NEFC gives us peace of mind.”

Pacific Press Innovations is all about the future. This Seattle startup (yes, they’re still considered “new” in this industry!) has taken filter presses digital, integrating IoT sensors and AI to optimize performance in real time.

Their PI-SmartPress connects to your phone or laptop, sending alerts when maintenance is needed, predicting filter clogging, and even adjusting pressure settings based on slurry consistency. “We run a motor recycling plant, and the sludge composition changes hourly—one minute it’s copper-rich, the next it’s steel,” says Mike, a tech lead in Washington. “PPI’s AI learns from the data and adjusts the press automatically. We’ve seen a 25% increase in throughput and 15% less filter media waste. It’s like having a PhD in filtration working 24/7.”

PPI also offers a subscription model, where you pay monthly for the press plus ongoing software updates. “We get new features every quarter—last month, they added a carbon footprint tracker that shows how much energy and water we’re saving,” Mike adds. “For a tech guy, it’s like Christmas every time an ｕｐｄａｔｅ drops.”

Last but never least, Southern Filtration Group is the champion of small to mid-sized recycling businesses. SFG believes everyone should have access to quality filtration, so they’ve stripped out the frills (no IoT, no custom bells and whistles) and focused on what matters: durability, ease of use, and affordability.

Their SFG-100 model starts at under $15,000—a fraction of the cost of high-end presses—making it perfect for startups or family-owned shops. “We opened our scrap cable recycling business with just one truck and a dream,” says Carlos, who runs a facility in Texas. “SFG’s press was the first big equipment we bought. It’s not fancy, but it works—day in, day out. We’ve had it three years, and we’ve only replaced two gaskets. For the price, you can’t beat it.”

SFG also offers flexible financing, with terms up to 60 months and no down payment for qualified buyers. “They didn’t treat us like a ‘small’ customer,” Carlos notes. “The sales rep sat with us for two hours, going over our budget and needs, and even connected us with a lender who specializes in recycling startups. That kind of support is why we’ll never switch.”
