Description
AirFlow 40 Gallon Simplex Condensate Unit
The AirFlow 40 Gallon Simplex Condensate Unit is a
single-pump condensate recovery package designed for commercial HVAC,
boiler-room, and industrial steam applications.
The 40 gallon simplex series is available with pump selections from
1/2 HP through 2 HP. Pump selection should be based on the required
condensate flow and discharge pressure or total dynamic head rather
than horsepower alone.
