300mm Inflatable Drain Blocker

Temporary isolation for a substantial drain

The 300mm Inflatable Drain Blocker is the largest listed airbag option in this range, designed to seal a 300mm drainage route during major spill or firewater response. Restricting the pipe helps keep contaminated liquid within an area where responders can contain and recover it.

The blocker works by inflation inside the drain, creating a temporary internal seal. For a product at this scale, advance checks around dimensions, access and the inflation arrangement are central to dependable deployment.
