Pulley Mount Filter System (Patented)
This easy to use ahu inlet filter system is easy to operate by simply pulling on a couple of ropes which raise and lower the filter over the intake louver.
This AHU Inlet Filter (commonly called cottonwood filter screens, hvac intake filter, air intake screens etc.,) eliminates / reduces the need to climb on a ladder and significanly cuts down on the
time needed to remove or install the filter during the winter off-season and spring start-up.
