Parson Odoreater is a specially designed manhole insert, with the addition of a canister containing 20 lbs. of activated carbon, that traps and stores unpleasant hydrogen sulfide and methyl mercaptan odors. Purified air is then allowed to ventilate into the atmosphere through the canister lid. A one-way valve allows water to drain but no air to pass through it.
-Compact and corrosion resistant
-Does not require routine maintenance and carbon can be replaced without removing the entire unit from the manhole
-Won’t interfere with installation or removal of the manhole cover
-Twenty-pound bags of replacement carbon are available
-Custom-sized for perfect fit. Ask for our sizing/measurement guidelines.
