The ProAir line of filter fan packages offers quick installation with simple, snap-in mounting. The exhaust grills are less than 0.25" thick. The filter packages offer a means of protecting enclosed electronics from heat and dirt while maintaining an even temperature throughout the enclosure. They maintain an IP54 rating on the enclosures when the filter gasket is in place. Maintenance friendly features include easily removed grill on outside of the enclosure for filter cleaning or replacement, angled louvers that prevent mechanical damage as well as entry of moisture into the enclosure, and fan motors that can be installed to either blow air into or draw air through the enclosure.
