MagnaFlex Air Filters feature "bend-to-fit" flexibility and an innovative magnetic installation and sealing strip that ensures a tight fit in medical electronics equipment enclosures. They are designed specifically for medical enclosures that cannot accept a rigid air filter frame because of enclosure obstructions. The magnetic sealing strip eliminates expensive mounting hardware and simultaneously locks the flexible filter in place. The resulting tight air seal prevents unfiltered airflow from bypassing the air filter. Universal Air Filter Co.
