3/8" Solar Automatic Air Vent

High temperature venting chamber with opening float valve for the automatic venting of air from solar thermal systems.

With 3/8" bsp connections.

It is good practice to use with an isolating valve so that the airvent can be removed for maintenance without draining the system.

Care should taken in considering just where the vent should be located. Usually at the highest point in the system, but accessibility should also be considered.

Note, this improved version exceeds the previous high temperature max of 160°C, but 180°C on this new valve can only be achieved in short temperature peaks.
