Description
The Bosch HVAC 7098822 Air Vent Revision Set is a replacement component used to remove trapped air from the hydronic circuit to ensure water flow and heat transfer. It is used in compatible GB series boilers where air can build up and cause a loss of efficiency or imbalance of flow in HVAC systems. It releases accumulated air automatically to ensure the stability of the system pressure and smooth running of the heating loop. This is an internal venting system of the boiler, which works to ensure performance for residential and light commercial heating applications.
