Our OdorKnocker™ unit is made of 18 Gauge 304 Stainless Steel which is hydraulically spun to shape from a single sheet of SS. We do not weld as welds may be weakened by the action of H2S.
Our odor control media is non-hazardous in its new and spent form. It is made from recycled material and is EPA and OSHA approved. Under normal conditions, one cubic foot of media will convert 15 lbs. of H2S. The media binds with the H2S and converts into iron pyrite, or fools gold.
Unwanted rainwater adds to the cost of sewage treatment. Eliminate unwanted rainwater & produce revenue for your city by reducing sewer treatment costs. Rainstopper Manhole Cover Inserts are built to prevent unwanted rainwater, snowmelt, sand, dirt, and trash from entering your system through the manhole cover.
