Purpose and fit
The Taco Inc 49-125T-2 is an automatic air separator built for hydronic heating and cooling systems. It removes entrained air from water or glycol circuits to maintain efficient heat transfer and quiet operation.
Build and connections
The brass body provides corrosion resistance for closed-loop applications. An in-line configuration with a 4 1/2 inch port spacing simplifies installation in existing piping, while a 1/2 inch female NPT connection accommodates a standard expansion tank.
Thermals and pressure
Rated for a maximum pressure of 150 psi and a minimum fluid temperature of 25 degrees F, the unit handles typical boiler and chiller conditions. A float-type vent discharges collected air automatically without manual intervention or external power.
