• Patented pall ring design Eliminates air induced system noise Minimal pressure loss Vent can be closed Large surface contact area Protective vent plate Rugged dependability Maximum air removal Convenient expansion tank connection tapping No minimum run of pipe requirement Bi-directional flow

The Taco 4900 Series bronze air separators are designed for the complete elimination of air from closed loop heating and cooling systems up to a maximum temperature of 240 deg F and a maximum pressure of 150 psi. The principle on which the 4900 Series bronze air separators is based is a patented and proven method of removing gases from water the pall ring process. The ultimate micro bubble separation of the pall ring process eliminates the damaging effects and irritating noise caused by unwanted system air.
