Amtrol 701-30 Air Vent Float Type 1/4" MPS 150 PSI 701-C

The Amtrol 701-30 Float Type Air Vent 1/4″ MPS Model 701-C is used for the HVAC systems to automatically vent trapped air from hydronic heating systems. It operates through a float mechanism that detects air buildup so that it can vent excess air without intervention. This support to keep the system pressure at an optimum level and avoids air-related problems such as noise or loss of efficiency. Frequently applied in boilers, radiators and other HVAC equipment, it allows for a smooth operation, better distribution of heat, and longer system life and while increasing energy efficiency and decreasing maintenance requirements.
