What is the difference between the Pulley-Mount and Snap-lock Air Intake Filters?
The Pulley-Mount Filter is specifically designed for medium to large air intake openings and comes partially assembled inside of a galvanized storage container that mounts on or below the unit. When fully assembled, the filter raises and lowers in and out of the storage box using a pulley and rope. In contrast, the Snap-Lock Filter is designed for small and medium size openings and come equipped with snap saddles that mount around the outer edge of the air intake opening. Filters then snap onto the mounted snap saddles.
