The Worcester Bosch air vent discharges accumulated air and is a safety feature for central heating. A float controls the vent's opening and closing according to the water level as it moves through the system. When the system is full, the float is forced to the top, shutting the vent until the water level falls.
Compatible with multiple Worcester boiler
