  • 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 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
