AAV - primary ventilation (universal, diameter range: Ø75 ÷ Ø114)
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.
