The 1800 Odor Control Vent Valve connects to a candy cane-style pipe, and is designed to allow for ventilation in the open position. The valve body may be easily disassembled with 2 quick release lockable metal latches. The interior of the body contains a canister filled with odor media. This media is in pellet form allowing for better airflow thru the media bed, and is highly effective in removing hydrogen sulfide gas (H2S) by means of chemically absorbing the H2S gas and changing it to a non-toxic compound. Blue indicator pellets turn white when the media is spent. Cast in 356-T6 aluminum, with epoxy powder coat finish. Standard 4-in. flanged. Larger sizes and/or materials upon request.
