The U.S. Navy CBRN filter housing is used in shipboard collective protection systems (CPS) to remove chemical, biological and radiological and nuclear contaminants from outside makeup air. While designed for use on ships, the system’s modular construction has led HDT to use the same design in fixed site installations such as buildings and underground facilities.
- Aluminum filter housings hold from one to five M98 particulate/gas filter sets for airflow rates up to 1,000 CFM (1,700 m3/h) 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.
- Two-piece front cover for independent tightening of M98 gas and particulate filter stacks
- Often installed in “banks” for greater flow capacities, with ship applications these banks are located upstream of ventilation supply fans for “pull-through” airflow. Air leaving the filter housings flows into an outlet plenum through slots in the back of the housing.
- With thousands of units built, installed and operating on a full-time basis, HDT’s U.S. Navy CBRN filter housing has emerged as a proven standard for collective protection systems
