A5345 | THERMOSTATIC AIR VENT | Armstrong International

Armstrong NCO Series Thermostatic Air Vent (A5345) Armstrong International's NCO Series Thermostatic Air Vent (A5345) is designed to automatically release air from heating systems, optimizing system efficiency and performance. This thermodynamic air vent features a brass body for durability and resistance to corrosion. The NCO-A5345 operates on the principle of thermal expansion. As the system heats up, the vent's elastomer plug expands and seals the vent, preventing air from entering the system. As the system cools down, the plug contracts and opens the vent, allowing trapped air to escape. This automatic operation ensures continuous air removal without manual intervention. The NCO-A5345 is suitable for use in both steam and hydronic heating systems. Its compact design allows for easy installation in various locations, including radiators, convectors, and baseboard units. The vent's high discharge capacity effectively removes air, minimizing system noise and improving heat transfer.
