The ESAVB15C allows quick and easy removal of trapped air from sealed heating systems without draining down the system and reduces, and often eliminates, the need for bleeding. The ESAVB15C is a cylinder-style Automatic Air Vent with 15mm compression fittings. It can be fitted anywhere in the positive pressure side of the system where air is likely to be trapped, although it should be installed in an accessible and visible area to ensure it can be serviced easily.
