Since 1957 Permatron has designed and built made-to-spec custom air filters for various applications and pieces of equipment.  The first washable electrostatic air filter was designed by Permatron for use in high dirt load environments, such as paper mills and food processing plants. Since then, we have manufactured custom air filters for thousands of satisfied customers by meeting their exact specifications and performance needs.  We provide both industrial air filters and commercial air filters, including aluminum mesh filters, synthetic material filters and a variety of other air filter media.

Permatron is also the leading designer of air filter screens. Our PreVent® filter screens work as pre-filters for use on outside and inside air intakes, catching debris before it can enter the system. Our one-of-a-kind HailStop® hail guard netting can also help protect outdoor equipment, such as HVAC units, from hail damage.  Both of these products are custom sized and easily integrated with any size HVAC equipment.

Our air filters and air filtration products can be used to catch airborne particles and debris of almost any kind.

Custom Air Filters

Data Center Free Cooling -- Not Free of Debris

The downside to "free" cooling is that it relies on efficient transmission of outside air through equipment fin coils to allow fans to work at maximum efficiency with the lowest energy input. A large data center for a major bank, located in the United Kingdom, had four new dry air coolers fitted for the facility. Manufactured and installed by Coolers & Condensers Limited, it soon became evident to them that local environmental conditions were going to cause system problems.
