Stainless Steel Air Operated Vapour Vents
Liquip's AVV3SSxx is an air operated chemical vapour vent that has been designed for superior chemical compatibility and resistance.
The AVV3SSxx is a sequential vapour vent with the exhaust from the previous vent opening the next in line. The outlet from the last vent can be used via a pressure switch to activate the overfill protection system, once all vents are open.
It has a 90mm nominal diameter opening for reduced pressure drop and increased vapour flow during loading and unloading.

- 90mm nominal diameter opening for minimum full 80mm flow throughout.
