Millions of dollars and thousands of man hours are spent annually on HVACR system or sensitive equipment downtime, repair and maintenance. Failure to provide effective air intake protection to building or equipment fans, motors, heat exchangers and other process cooling systems adds up to a costly loss of productivity in safe and efficient system operations.

Permatron’s PreVent Equipment Protection Filters are made of permanent, washable polypropylene. A primary prefiltration defense, they help prevent the damage and extensive maintenance that large volumes of debris can cause. Custom sized to fit any air intake, PreVent is UV protected and stands up to extreme outdoor or indoor exposure, corrosive environments, high velocity air flow, as well as industrial cleaning and maintenance handling. Our simple solution to air intake filtration helps reduce operational and maintenance costs over a long useful life.

Permatron PreVent Outdoor Air Filter

New AC Systems

Existing AC Systems

Dirty Coils Reduce Heat Transfer and Increase Electricity Consumption.

Average Outdoor Air Flow through the AC Condenser Coil is 800 CFM / Ton AC.

A 5 Ton unit moves 4000 Cubic Feet per Minute Air Flow through the outdoor coil. 

4000 CFM/min x 60 min/h x 2000 hours/AC season = 480 million cubic feet of air / AC season.

Average Indoor Air Flow through the AC Evaporator Coil is 400 CFM / Ton AC.

Moisture in the system and Freon R22 Chlorodifluoromethane  CHCLF2 break down under high temperature & pressure to form HCL Hydrochloric Acid (strong acid) and HF Hydrofluoric Acid.
