Airfix A expansion vessels prevent stagnant water and bacterial growth, maintaining high quality potable water and prolonging the life of safety groups and valves. It can also be used in basement applications with higher drains.

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.
