Description
The Armstrong International A5572 3/8” vacuum breaker is an essential part that helps prevent problems such as freezing and water hammer in HVAC systems. Constructed from high-grade stainless steel, it mounts directly to the top of traps in condensing equipment and maintains its modulated control. This vacuum breaker self-drains the vacuum at a certain point to improve system dependability and efficiency. It is typical for use in many forms of heating, ventilation, and air conditioning such as steam heating systems and condenser return systems. The advantages are the protection of equipment, low maintenance costs, and energy conservation through the regulation of pressure in the system.
