Keeping up With the PreVent System Couldn’t be Simpler

They Already Trust Us

  • 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.

  • As a new Territorial Manager in the Portland Oregon area for Total Filtration Service, Permatron gives me a great product and support that helps me find solutions for my customers. I live and work in an area where cottonwood is a killer on the mechanical equipment where larger debris needs to be stopped from entering a certain space.I can offer air filter solutions to my customer to help save them time and money. A few ways that the PreVent screens can help:

    • Save from having to do frequent coil cleanings because of cottonwood
    • Save from having to spend money on mechanical equipment break downs because the equipment wasn't protected from the harsh conditions
    • Save on labor costs from filter changes and maintenance cleanings promotes reallocation those labor hours to other critical projects
    I want to be valued as a total filtration representative to my customers (i.e., bakery facilities, city municipalities and mechanical contractors), and the PreVent benefits allows me to do so.

  • 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.

  • 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.

  • 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.

  • 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….

  • 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.

  • 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.
