Description
The SKAS provides combined air release and vacuum breaking for sewage systems operating under both gravity and pressurised conditions. Non-clog internals and a ball float resist fouling from wastewater constituents. Vacuum break function protects pipe walls from collapse during drain-down or sudden pump shutdown.
