Housings guarantee filter system efficiency equal to the efficiency of the individual filters. Optional prefilter tracks are designed to accommodate 2 in. pleated panel filters with efficiency ranges up to 50% per ASHRAE Standard 52.1 dust-spot test methods. Both prefilters and primary HEPA filters are serviceable through gasketed access doors. Options • Prefilter tracks • Double-walled insulation on doors only or on the entire housing • Aluminum or 304 stainless steel housing construction • Modifications for high temperature (400 °F continuous, 500 °F intermittent duty) • Swing-arm assemblies for 6 in. deep HEPA filters Construction Housings are 27 in. deep in the direction of air flow and are constructed of 14 ga. galvanized steel. Upstream and downstream outwardly-turned flanges are furnished for attachment to the ductwork. Each HEPA filter is secured in place by four positive- pressure spring-loaded swing-arm assemblies which maintain continuous pressure on the filter gasket against the sealing surfaces. Optional prefilter tracks are galvanized steel furnished with a pile gasket. Hinged/removable access doors are furnished with rubber sealing gaskets and positive- pressure adjustable latches with easy-grip knobs on the air entering and the air leaving sides to create an airtight seal. Metal-to-metal joints are welded to ensure a leak-proof assembly at + 8 in. w.g. internal pressure. Versatility Surelock-B Housings are designed to accommodate Alpha 95 filters with a DOP efficiency of 95% and Alpha Cell and Alpha 2000 filters with DOP efficiencies of 99.97%, 99.99% and 99.999%. Standard housings will accept nominal 12 in. deep 24 in. x 24 in. and 24 in. x 12 in. filters from one filter high and one filter wide to four filters high and six filters wide. If large units are not practical to install, smaller units are available with modifications to facilitate stacking. Important Features • Units are constructed of durable 14 ga. galvanized steel • All metal-to-metal joints are welded for leak-tightness at + 8 in. w.g. internal pressure • Prefilter tracks and doors are fully gasketed • Positive-pressure adjustable door latches create an air-tight seal • Spring-loaded swing-arm assemblies hold HEPA filters to sealing surface • Access doors are hinged/removable for easy service Flanders Filters - Foremost in Air Filtration Toll Free: 1-800-637-2803 Cfm Capacities and Dimensions Using Standard Alpha Cell and Alpha 2000 High Capacity HEPA Filters Height Code Overall Flange Height (in.)

Height and Width Code: The first numeral represents the number of 24 in. x 24 in. filters high or wide. If 24 in. x 12 in. filters are also used in the height width, the second numeral is “5”. 2. Standard housing depth is 27 in. with or without a 2 in. prefilter track. 3. For capacities and pressure drop other than those shown, ratio the face velocities. 4. Capacities shown are based on Standard (Std) and High Capacity (HC) 99.97% and 99.99% Alpha Cell filters nominal 12 in. deep and actual face sizes of 24 in. x 24 in. and 24 in. x 12 in. 5.
