Auto Air Vents for Gas Boilers

Auto Air Vent

An auto air vent is a mechanical device which automatically releases air trapped within a water system - normally fitted at the highest point of a plumbing system. Auto air vents are also used in heating systems and on water heater discharge lines. Auto air vents can be known as AAV, bottle vents, auto purger and auto de-aerator.

Manufacturers of auto air vents include caleffi and altecnic. It is important to take your time to find the right Auto air vent for your Gas Boiler. We have a large range of spares in stock at DHS and if you are unsure please give us a call.
