Case Studies

  • The distributor you got me in contact with sent me the three PreVent Model R filters I was looking for. They are working great. Thank You.

    Robert M. CoutureSeaman Paper Company of Massachusetts, 3rd Class Steam Engineer
  • We had to change a combined condensing / free cooling coil because it was so badly damaged from debris and washing. 10k€ (approx. $12,000 USD)  for the coil and works and 6k€ (approx. $7000 USD) for the crane hire. The second chiller on the site is perfect as the screen was fitted back some time ago.

    Dave ClarkeCORE AIR CONDITIONING, SERVICE MANAGER
  • 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.

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

    Dave GaborekHyatt Regency Ohare, Chief Engineer
  • 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 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
  • 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.  

    Jim PodrazaArgonne National Laboratory, Planning Manager
  • 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.

  • We receive outstanding customer service, receiving our products in a timely manner and are of excellent quality. Measuring for PreVent air intake filter is easy to understand and complete. Installing PreVent is simple and the product works efficiently.

    Jake DanielsDaniels Filter Service, Des Moines, IA
  • 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.

  • 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.
  • 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.

  • Thanks to Permatron screens maintenance engineers in Utah save tons or time in preventive maintenance. Thank you Permatron!

  • The installation of the Permatron PreVent filter has saved us money, reduced downtime, and to date eliminated any possible environmental outages.

    Gary WilcoxOsram Sylvania
  • 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!

  • 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.

    John JarrattAir Compressor Energy Systems, Louisiana
  • 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

  • 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.

  • 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.

    Jim HoffmanCapital Air Filters, Inc, Raleigh, NC
  • 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
