Saferise® - Anti-Slam Clean Water Air Valve
CSA FOX 3F-HR
Combination Anti-Slam Air Valve For High-Rise Buildings And Pumping Stations
CSA's double-orifice air valve with an integral engineered surge anticipation and alleviation mechanism.
Designed to overcome potentially damaging effects of hydraulic surges associated with water boosting systems in high-rise buildings, vacuum prevention on pump failure and column separation.
Allows the efficient intake of bulk air during the draining cycle while accurately controlling the discharge speed during the charging cycle.
See our Working with Air Valves document for more information.
