Airfix

Applying an Airfix 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.

No waste of valuable potable water. 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.
Colour: White RAL9010. Vessels in accordance with EN13831. In accordance with Pressure Equipment Directive 2014/68/EU.
