Description
The Armstrong International C5491 TAVB-3 is a premium-grade combination unit that integrates a stainless steel thermostatic air vent with a vacuum breaker in a single, compact assembly — ideal for steam and hydronic heating systems where reliable air elimination and system protection are critical.
Product Overview
Designed for demanding commercial and industrial hydronic and steam applications, the TAVB-3 automatically vents non-condensable gases and air from the system while the integrated vacuum breaker prevents the formation of damaging vacuum conditions. The all-stainless steel construction ensures long-term corrosion resistance and durability in high-temperature, high-pressure environments.
