Particularly suitable for environmental protection, the PRONAL OFR anti-pollution stopper can deliver a high-speed and impeccable seal over diameters ranging from 1000 mm to 2115mm.
OFR inflatable anti-pollution stoppers are designed to remain permanently in the line concerned, in order to ensure immediate stoppage in case of accidental pollution. Positioned in the central axis of the line using the support provided, the OFR is designed for lines of large diameter.In case of pollution, the stopper inflates and acts as a valve for the retention of pollutants, which can then be pumped away or diverted to a retention tank. Any risk of pollution is eliminated accordingly. A polythene bag protects the stopper when not inflated. Inflation can be initiated from a control box. The inflation pressure will be determined according to the diameter of the line concerned.
Designed for the conservation and protection of the environment, the main advantages of the PRONAL OFR anti-pollution stopper are its rapid stoppage action, its permanent installation, its high resistance to wear and to certain pollutants, and the option for manufacture to specific outlines.
