DrainSafe is a serviceable unit that retrofits inside an existing drain pit. Once installed it sits entirely beneath the drain grate. It does not impede wheel of foot traffic over the grate.
In the event of an oil, fuel or chemical spill, the mechanism that closes the unit and stops flow into the stormwater system is engaged manually by extending and turning the handle within the unit. This prevents spill liquid entering the stormwater system.
The stainless steel handle stows in a protective sheath within the diffuser body and beneath the grate. Once engaged, the telescopic handle will extend 500mm above ground level out of the grate for easy open and closing action.
In normal use, debris is automatically captured in the diffuser body and hydrocarbons are absorbed by a material and secured within the diffuser body until routinely removed for disposal.
