Description
The AERCO 122770 Vacuum Breaker is a genuine OEM replacement component engineered for use with AERCO boiler and water heating systems. Vacuum breakers play a critical role in hydronic and steam system integrity by preventing back-siphonage and protecting against the damaging effects of negative pressure. When a system experiences a pressure drop, the vacuum breaker opens to admit air, breaking the vacuum and stopping the reverse flow of water or steam condensate that could compromise system components, water quality, or equipment performance.
