Flat Drain Guards sit underneath the stormwater grate and remove sediment and up to 98% of hydrocarbons that flow through them. Their catchment zone has an overflow space located at the top to ensure that blockages will not occur even when the filter is full.
Flat Drain Guards are simple to install. The installer just needs to place them underneath the drain grate, then attach ties to the grate for added security and trim to size.
They let the water run through them but have 2 integrated oil and fuel absorbent pads that can absorb up to three litres of hydrocarbon.
