NAVIEN 30012277A Pump Air Vent Assembly NCB

The Navien Tankless Water Heaters 30012277A Pump Air Vent Assembly is an essential part of the NCB series HVAC systems. This assembly ensures that the pump is relieved of trapped air ensuring optimum performance and preventing airlock issues that would compromise system performance. The air vent component eliminates accumulated air so that it can enhance a continuous flow of water through the pumps. It mainly becomes a solution for increasing the durability and efficacy of the HVAC system by eliminating pockets of air, which not only can cause noise and reduced efficiency but may also be damaging to the system.
