CBR Filter Housing, U.S. Navy A marine-grade CBR filter housing built for survivability Copyright 2009 HDT Engineered Technologies. All rights reserved. Engineered to move with you. www.hdtglobal.com Product Description U.S. Navy CBR filter housings are an integral part of ship collective protection systems (CPS). They are designed to house M98 gas/particulate filter sets for removal of toxic chemical, biological, and radiological (CBR) agents under the harshest environmental conditions. They are qualified to high-impact military shock (Mil-S-901) and vibration (Mil-Std-167) in housing lengths to five (5) filters deep. The U.S. Navy CBR filter housing features a two-piece front cover for independent tightening of M98 gas and The U.S. Navy CBR filter housing is used in ship collective protection systems (CPS) to remove chemical, biological, and radiological (CBR) contaminants from outside make-up air. These aluminum filter housings hold from one (1) to five (5) M98 gas/particulate filter sets for air flow rates up to 1,000 cfm per housing. They have been qualified to military shock and vibration standards for shipboard use. They are constructed of aluminum and anodized for maximum corrosion resistance in marine environments particulate filter stacks. The gas cover, or outer ring, mounts to the front of the housing, while the inner HEPA cover mounts to the gas cover. Covers are secured using spring-loaded nuts with indicators that recess when the proper torque is achieved. Filter housings are constructed from aluminum and anodized for maximum corrosion resistance. They are available painted with military-grade epoxy paint, as shown in white above. U.S. Navy filter housings are often installed in “banks” for greater flow capacities. For ship applications, these banks are located upstream of ventilation supply fans for “pull-through” air flow. Air leaving U.S. Navy filter housings flows into an outlet plenum through slots in the back of the housing. With thousands built, installed, and operating on a full-time basis, the U.S. Navy CBR filter housing has emerged as a proven standard for collective protection systems.
