Airfix A 8 – 80

For use in potable water or fresh water installations.

The Airfix A expansion vessels operate in such a way that the water flows right through and they are continuously flushed with fresh water from the mains. This prevents tepid, stagnant water from collecting in the vessel in which bacterial growth could occur. Therefore, users can be assured of high quality potable water.

Applying an Airfix A expansion vessel to a water heater prevents the opening of the safety group or safety valve each time the potable water is heated. As a result, not only the life of the safety group or safety valve is significantly prolonged (damage or calcification of seat is avoided) but also the risk of permanent leakage (with high water loss as a consequence). An Airfix vessel is also a perfect solution in basement applications where the drain is higher than the safety valve.

Airfix A is a flow through vessel, that operates by diverting some of the connection fluid flow into the vessel to prevent stagnation.

Partial diversion flow through.
The Airfix A is fitted with a synthetic flow through device in a standard T-piece (not included) which eliminates the formation of unwanted bacteria inside the vessel.
Including synthetic flow divider.
No waste of valuable potable water.
With special flow through construction.
Continuous flow through prevents bacterial growth.
Special butyl rubber diaphragm does not add any colour, odour or taste to the water.
Corrosion-resistant coating inside, not only on the water side but also on the nitrogen side.
The two halves of the vessel are coated prior to assembly, not afterwards. Therefore there is no risk of corrosion on the clamp ring and the diaphragm does not have a service life-reducing thermal shock during production.
Nitrogen gas filling for longer retention of pre-charge.
Internationally approved and certified.
Airfix A can be fitted with an Airfixcontrol. Airfixcontrol enables an easy yearly precharge check of the Airfix expansion vessel.
