Custom Filter Manufacturer

In-house testing is one way we ensure performance and quality while saving our customers money. The tests conducted in our lab and wind tunnels monitor airflow and particle capture efficiency. Each filter is labeled noting filter efficiency, pressure drop, rated air flow, serial number and lot number for unit tracking to meet our quality assurance standards. Additionally, we often work with 3rd party laboratories to have our products tested as requested.

Our capabilities also include 100% HEPA testing

• Box
• Square
• Round
• Cones
• V-banks
• With or without sealing gaskets

• Options include foam-in-place and die cut in a wide range of materials

• Options include hot melt, urethane, silicone

The ultrasonic welding process provides lower resistance and allows filters to be manufactured without stitch holes in the media, all while maintaining durability

Our high-speed presses handle high volume jobs and our 60” wide press can be used for larger part geometries

As one of the leading global producers of HEPA (High Efficiency Particulate Air) filters, we design and manufacture an array of OEM, aftermarket and custom HEPA air filters for industrial, commercial, healthcare, and household products. HEPA filters as defined by the Institute of Environmental Science & Technology (IEST) must capture a minimum of 99.97% of contaminants down to 0.3 microns in size. This means for every ten thousand 0.3 micron particles that enter the HEPA filter, no more than three particles will pass through. We have state of the art manufacturing and testing facilities for HEPA and ULPA filters.

Just using HEPA media in a filter design doesn’t guarantee a true HEPA-performance filter. For instance, the filter and its frame need to be engineered with a tight seal so air and particulate isn’t able to go right past the filter without getting caught. We take factors like these into account when designing your filter to ensure it meets the highest quality and performance standards. Some of our custom HEPA filter design capabilities include:

• Cartridge, Panel, or V-Bank
• Tested in house to IEST standards
• Pleated in class 10,000 clean room
• Metal or molded frames/end caps
• One piece or dovetail gaskets

Our air purifier product range includes pre-filters, high efficiency filters such as HEPA and ULPA, and specialty carbon filters.

• Panel, cartridge or custom geometries
• Pre-filters, HEPA, Carbon
• Metal, chipboard, plastic, molded style frames/end caps
• Built to meet OEM standards

We have high-speed presses for high volume jobs and a 60” wide press for large part geometries. If you have a die cut part you need, R.P. Fedder can help.

• Small to large geometries (up to 55” wide)
• Foam, ASHRAE, carbon, or laminated medias
• Gasket materials include foam, neoprene, poron, etc.

Typical applications are vacuum systems, conveying systems, powder booths, and wood dust collection filter elements.

• Standard and custom sizes available
• Cellulose blends, Spunbond, PTFE membrane, nanofiber media available
• Engineered solutions for troubled collectors
• High-efficiency pleat design

We’ve been capturing pesky toner dust since 1959. In fact, that’s how our business began: designing and manufacturing the toner bag filter for the first generation Xerox machines. Our expertise and longevity in this industry has made us a key supplier of filters, cleaning and oiler belts, and bottled silicone fluid for manufacturers around the world.

• Toner filters
• Oiler belts
• Ozone filters
• Bottled silicone sluid

Foam air filters are available in a variety of reticulated open cell polyester, polyurethane and polyethylene foam filter medias. Applications include vacuum cleaners, appliances, industrial equipment, cabin air filters, CPAP, oxygen concentrator filters, dental appliance air filters, electronic equipment air filters, HVAC air filters, medical equipment air filters, and specialty filters for our military.

• Cartridge wraps
• Ultrasonic welding
• Laminating gradient densities available

Medical filters include carbon filters, cartridge filters, capsule filters, disc filters, foam filters, HEPA filters, panel filters, pre-filters and ULPA filters used in a variety of medical appliances and equipment.

If you need a filter designed to meet EPA safety requirements for lead paint abatement or asbestos removal, we can help.

In welding operations, workers are in contact with harmful fumes like Hexavalent Chromium, which is made up of submicron particles – detrimental to human lungs. Our HEPA filters eliminate those harmful particles and carbon filters aid in fume reduction.

• Certified filters to remove Hexavalent Chromium
• Industrial strength build quality
