RMC Water Hammer Arrester 20mm 7002
Product Specs:
The water hammer arrester works on the principal of compressing air to absorb the induced pressure wave. The arrester is placed at 90 degrees to the water flow, just upstream from the offending device. When the device closes the pressure wave begins to move back along the pipe. As it reaches the arrester the force acts against a piston which in turn pushes against a charge of air, the air is compressed, dissipating the wave energy and nullifying the hammering effects.
