Bulk Air Filter Media

Service Rolls and Custom Pads

Permatron’s air filter media capabilities include material slitting, sheeting, die cutting, sonic welding, sewing, fabricating and assembly. Permatron works with a diverse selection of washable and disposable air filter materials or ‘media.’  Cut-to-fit media by the linear yard or in custom sized pad ordering options work well for register vent, PTAC, appliance (window/wall air conditioners) and electronic (computer CPU) applications.

Features and Benefits

  • Activated Carbon is a dual action media for particulate and odor/fume removal.  An effective way to remove and prevent odor / fume buildup in recirculated air. Nonwoven polyester is impregnated with a finely ground activated carbon coating and heat-set to retain the coating even when the media is rinsed or vacuumed.
  • Aluminum Mesh is lightweight and corrosion resistant.
  • Polyester is a nonwoven synthetic air filter media, where the fibers are randomly dispersed in all directions through an air laid web to form a uniform media of high strength and durability. A high volume of contaminants can be trapped within the complete depth of fiber.
  • Polypropylene is a synthetic media that comes in a weave type, used extensively within the air filtration industry as an open weave fabric that effectively removes airborne particulates through a combination of impingement and a triboelectric “static” charge for an enhanced attraction of airborne particles, like iron filings to a magnet. Polypropylene is a petroleum industry by-product which has impressive strength, and resistance to abrasion, most acids, alkalies, bleaches, solvents and aging. Not attacked by mildew, this media will not disintegrate, unlike other air filter medias. Natural white polypropylene media is an FDA approved component, and can be used in food processing applications. Black polypropylene media is UV protected, and can be used outdoors or in conjunction with UV lights.
  • Foam is thermally reticulated 15 and 20 pores per inch polyether polyurethane foam. Resilient and flexible, this foam air filter material is reusable and can be rinsed with water or vacuum cleaned.
  • Plastic Netting can be used as a protective barrier against environmental elements, nesting birds, and hail storms or layered as filter media support in air filters. It is UV protected, rot and corrosion resistant for outdoor use. Can also be used in an air filter in place of wire support.
  • PVC Coated High Abrasion is UV protected, rot and corrosion resistant for outdoor use.

Case Studies

  • I use the PreVent Model R filters with magnetic option that allows them to stick to the ironsteel surface of my Kaeser compressors, Kaeser air dryer and YASKAWA inverter on a Braun washer. I rinse with hot water once a week. These can be used in many applications and do save significant time for maintenancePM work. I also have installed this type filtration on all HVAC units. Easily eliminates 90% of lintdust that otherwise enters these areas

  • I attached a couple of photos of the completed PreVent Screens installed on Trane rooftop units. They fit very well to our dimensions and look good also. Your folks did a good job on matching all of our requested dimensions. I will keep you guys in our contact list as I can see several applications for your product that would be beneficial & it is another product we can offer to our customers.

  • I was not familiar with Permatron R-2 filters until I started working at Delta Industries. Now that I see how well the R-2 filters have been working I talk them up to my customers. A couple of our customers were so impressed the decision to apply R-2 filters to other applications such as water chillers and electrical control cabinets have proven successful. Industrial applications we have placed R-2 filters include machine shops, foundries, woodworking shops and even the CTA in a dusty bus garage. Other applications that have proven successful are shops that operate with open doors especially during the cotton wood and dandelion seeding seasons

  • We installed the PreVent filters last week; all panels were sized exactly as ordered, and the installation went very well. Our customer is very pleased with the results. We will be seeking other opportunities in our area.

  • I just sent off an email to my manager giving him all the info from Permatron so he can get this out to the rest of our After Market Sales people. I told him how happy I am and so are the customers that I been getting your product out to. Thanks for all your help with my end.

  • As you know, we offer your R2 magnetic filters as an option on our air compressors. The feedback from our sales people and customers has been very positive. The product is durable and offers a quality alternative to disposable filters. We are very pleased with the quick delivery times. In addition, the product does an excellent job keeping dirt away from the critical components on our compressors. As you probably know, compressors tend to be installed in the worst possible location. Just look for the hottest, dirtiest place in a plant and you will usually find the air compressor. Without the R2 filters our customers would experience greater service costs on their equipment

    Drew JohnsonKaeser Compressors
  • The R2 filters I have sold have worked very well. They do as advertised, by keeping the inside of our air compressors clean. No customer complaints after the sale and no problems with the construction of the washable filters. Your delivery times are fast and your customer service agents are a pleasure to work with. I look forward in continuing our business relationship with Permatron in 2013 and thank you for all of the continued support that we receive in making our compressors work better.

  • Thanks for the cleaning info, I love my PreVent filters as they saved me a lot of time on the roof in the extreme heat last summer. I've found a damp terry cloth rag removes the cotton very well. Thanks for the YouTube videos!

  • Several of our large commercial buildings in Atlanta have purchased the PreVent filtering product for their cooling towers. The benefits of being able to get through our spring season without much intrusion into the building owners equipment has been successful. The product was easy to install and has been simple for the customers to maintain. We are excited to have this product in our line of filtration options.

  • I am very pleased to work with Permatron when ordering the PreVent Filter for installations in Wisconsin. From start to finish Permatron is very timely in getting pricing right down to delivery. The finished product is always as accurate as the drawings supplied to have it made. The finished product is also very easy to install, modify if needed, and cleaning is super easy. The fasteners are a great way to have the filter installed if you need to take down the filter to clean it. Otherwise, just turn off the air and either sweep it down or hose it off.

    Sean T. McGlennClass 1 Air, Inc.
  • As a company who specializes in life cycle costing and energy efficient products in Seattle, we try to use the PreVent system whenever possible. We prefer to install our 4V style final filters without a pleated pre filter to maximize energy savings. This works very well except during our cottonwood season which can load up any filter in a matter of days. The PreVent system gives us the opportunity to remove the cottonwood seeds at a very low pressure drop. Having such a short lead time and being available in any dimension we require makes it an amazing addition to our product line and allows us to set our business apart in a very competitive marketplace.

  • PreVent is a very nice product, and very reasonably priced.  Belk is looking forward to the opportunity to do more work with Permatron in the future.

  • Permatron's PreVent screening was installed on recently replaced 363A RTU condenser coils, outside air and economizer openings, using MagnaMount magnets to hold them in place VS drilling and screwing them on. The magnets will most definitely be our primary mounting option going forward. All three screens took us literally less than five minutes to install. I noticed how quickly cottonwood was caught by the screening.The screens can be cleaned in place or easy removed for more detailed cleaning.

  • The PreVent bonnet style filter is the best thing I have ever bought to protect our cooling tower circular fan. We have to clean it every two weeks but it is so easy.

    Martyn RogersCotek Papers Limited, Maintenance Manager
  • Our customer, Logoplaste, uses and raves about the Prevent BHA Screens and MagnaMount Kits.We did an install at their manufacturing facility in June on two units, all four sides required screens. Installation time was drastically reduced from the original 6 hour estimate with standard mount clips, to complete screen installation in under 1 hour with MagnaMount clips.The facility is located along the river where cottonwood trees are very abundant. Even when installing PreVent, it was catching the cottonwood that was flying. I brought him out one of your cleaning brooms a week after install, and the Maintenance Manager said that it is the best money he has spent since he has worked at that facility. He is planning on purchasing some more for his 4 Cooling Towers as well.

  • The guys love them!  Clean look, and easy to clean….  

    Dave GaborekHyatt Regency Ohare, Chief Engineer
  • It’s always a great idea to protect HVAC condenser coils with screening, especially if you can do it right after new equipment installation. Once the magnets where inserted into the screen grommets, it took literally less than a minute to place the screening on the equipment, adjust it, done. This screening will protect the condenser coils from grass cutting, bugs, cottonwood seedlings, etc.
