AstralPool - Air & Water Purge Valve 3/4" - 4404160227

AstralPool – Air & Water Purge Valve 3/4″

This genuine AstralPool 3/4″ air and water purge valve is an OEM spare part designed for AstralPool sand filter vessels. It allows trapped air and water to be safely vented or drained from the filter body, maintaining correct operating pressure and filtration efficiency. It corresponds to position 4 in the official Fluidra exploded-view diagram for compatible filter assemblies.

Compatibility

This purge valve is compatible with a wide range of AstralPool laminated sand filters, including models 00693, 08695, 08700, 09221, 09222, 04935, 00700, 05103, 07129, 08696, 08697, 08699, 08701, and several others spanning pressure ratings of 2.5 and 4 kg/cm². Always cross-reference your filter’s model code and official Fluidra exploded-view parts diagram before ordering to confirm an exact fit.

Why Genuine Matters

Using a genuine AstralPool replacement ensures the valve meets the exact thread specification, pressure rating, and material standard of the original fitment. Non-OEM alternatives risk mismatched threads, inadequate pressure tolerance, and premature failure — potentially causing leaks or filter downtime. As a direct Fluidra part, this valve is manufactured to the same quality standards as the original component.

Installation

The valve is threaded at 3/4″ BSP, fitting into the dedicated purge port on the filter vessel. Always isolate and fully depressurise the filter system before removing the old valve. For technicians unfamiliar with pressurised filter systems, professional installation is recommended to ensure a safe, leak-free result.
