From cottonwood seeds to bugs, the PreVent® system stops airborne debris before it gets inside A/C units, cooling towers, chillers and other HVAC equipment. PreVent air intake filter screens fit on the outside of the unit, keeping contaminants from entering the system and protecting the vulnerable fill material and coils inside. With the extra protection of the PreVent air intake filter, your pleated, metal mesh or washable electrostatic air filters will last longer, and your HVAC systems will work better and more efficiently. PreVent air intake filters are custom-made in the USA to fit any outdoor air intake, and can be simply brushed or hosed clean, with zero downtime. Installation with our secure and patented MagnaMount® earth magnets takes minutes, with no drilling or tools. Plus, we offer the fastest turnaround in the industry and a five-year warranty.

I sincerely feel that each company should install a Permatron filter on every single piece of equipment that could benefit from it. I have recommended Permatron products to many other industries I deal with. These filters can save industries thousands of dollars in repairs and replacement costs as well as preventing lengthy and costly downtimes of their systems.
I visited Sovereign House today in Brighton, England. Those PreVent filters we installed on their Trane chillers are good as gold 6 years on - unbelievable quality doing a grand job still...
Everything was correct & professionally served, finely crafted with accurate dimensions of quality material. I will purchase further metal mesh filters from your firm in the future as demand calls for.
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.
The order process went very well. We received the black washable fan bonnets 2 weeks ago and are very happy. I will order again in the future. Great product and great service. Thank You!
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….
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.
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.
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.
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.
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.
The installation of the Permatron PreVent filter has saved us money, reduced downtime, and to date eliminated any possible environmental outages.
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.
I'd like to take a moment to thank-you for your support, your quick replies and your thoroughness throughout 2012. It has been a pleasure working with you and your team and I look forward to doing so again in 2013.
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
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 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
I have 2 customer problems that I solved with your products. These are both hospitals. One had a problem with air filters being damaged by moisture being pulled into them by powerful air handlers. The filters were failing prematurely. I sold them your Model IN filters 3 months ago for one of their air handlers. They just ordered more filters for a second air handler. They have seven more air handlers that could use the same filters, so hopefully there will be many more orders for these filters. The other hospital had a problem with leaves, insects and debris getting into their air intake louvers. I sold them the PreVent air intake screen, custom sized, to protect their louvers.
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 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 installed the HailStop coil guard today. My customer was pleased. I picked up a handful of gravel and thru it directly at the coil and it bounced right off. I was impressed. Will you get me a quote on another 3000 ft with hardware? I don't think that is going to be enough to do the entire job but should give me a good start.
