SurePleat side access filter housings are minimum depth units designed to accommodate ASHRAE rated filters that are 2″ (standard), 4″, or 6″ (optional) in depth. They are factory assembled flanged units suitable for installation in a duct or next to an air handling unit. As little as 12″ of inline depth are required with no need for holding frames or fasteners.

SurePleat housings accommodate filters of different types and efficiencies, up to 95% per ASHRAE Standard 52.1 dust-spot test methods and ASHRAE 52.2 Test Standards. Filters are easily serviced through quick-opening access doors. Factory-gasketed channels and doors ensure positive sealing. The efficiency of fully-loaded housings is equal to that of the individual filters.


Both prefilter and final filter requirements can be accomplished by using the combination 2″/4″ track. Surepleat housings are available in a wide range of sizes, up to 8 feet high and 12 feet wide. They can operate at face velocities up to 625 FPM with 4″ filters.
