Diaphragm aerator valve for water pressure relief column D32/40/50
The membrane aerator is used in place of primary ventilation.
It traps odours through the upper surface of the membrane that closes the air from the fall.
During an emptying, the membrane lifts and allows the essential air supply preventing the siphon from draining its water.
pvc membrane aerator Ø 32 40 50
it is used as a replacement for first ventilation
it traps odours thanks to its membrane that closes the air from the fall
it is generally placed at the end of a pipe to replace an opening in the roof, or on an appliance (shower, washing machine, dishwasher, sink)
The water, when discharged into a pipe, creates a depression that sucks water from the siphons and allows bad smells to pass through.
To avoid this depression, the aerator membrane will lift and allow enough air to pass through to avoid any defusing of siphons
