Anti-pollution inflatable plug
ø 100 - 1 000 mm | OPAP series
Pronal anti-pollution stoppers have been designed to remain permanently fitted in water and sewer pipes so as to quickly stop the pipeline when accidental contamination occurs.
To do this, simply trigger stopper inflation using a remote-operated system.
Once inflated, it will prevent any toxic fluid spill or spreading of firefighting water in the pipeline.
