4900 Series Bronze Air Separators

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°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.
