Standard materials of construction include carbon steel enamel coating or stainless steel material contact areas. Mounting on a standard 20 in. diameter tank deck, the small modular unit is inexpensive and easy to install. The cartridge filter hangs vertically and has shallow, open pleats for efficient dust release. Quick-release clamps allow easy access to the cartridge filter. The plenum features a built-in weather hood and specially designed diffuser which enables each air pulse to clean the entire filter. Unlike other bin vents, no exhaust fan is required.
