PVC Air-admittance valve (AAV)

Products for ventilation of the waste system.
The use of ventilation valves allows air to enter, decreasing depressurization during discharge and that cause siphons to empty, while blocking pungent fumes from escaping.
Good design of a ventilation system allows:
- increase of discharge capacity
- reduction of noise generated during discharge
- thorough emptying of the system.
Norms: EN 12056 Air admittance valve systems, EN 12380 Air admittance valves
Compliance with EN 12056 norm
