AstralPool - Air Purge Valve for Viron QL420 & QL540 Cartridge Filter - 4404130039

AstralPool – Air Purge Valve for Viron QL420 & QL540 Cartridge Filter

This is the genuine AstralPool replacement air purge valve (position 5 in the official Fluidra exploded view) for the Viron QL420 and QL540 cartridge filter range (parent SKU 76340). The air purge valve is mounted in the filter lid and allows trapped air to be safely vented from the filter tank, ensuring correct water flow and consistent filtration performance. Replacing a worn or damaged air purge valve promptly prevents pressure irregularities and potential water leakage at the lid.

Compatibility

This air purge valve is designed exclusively for the AstralPool Viron QL420 and QL540 cartridge filters (parent SKU 76340). It corresponds to position 5 in the official Fluidra exploded view diagram. Always cross-reference your filter’s model number and exploded view before ordering to confirm fitment.

Why Genuine Matters

As a genuine Fluidra/AstralPool spare part, this valve is manufactured to the exact tolerances of the original component, ensuring a reliable seal under the high operating pressures of the Viron QL filter system. Non-genuine alternatives may not seat correctly in the lid, risking leaks or inadequate air bleeding that can reduce filtration efficiency.

Installation

The air purge valve threads or clips into the designated port on the Viron QL filter lid. Ensure the pump is switched off and the system is fully depressurised before removing the old valve. Refer to the official Fluidra installation and operating instructions for the Viron QL420/QL540, and if in doubt, consult a qualified pool technician.
