The Gast 0523 (0523-101Q-G588NDX) rotary vane septic air pump is a highly reliable septic aerator designed for years of service. Using 115v 1/4 H.P motor and producing 4.5 C.F.M of air at a maximum 10 psi. The 0523 from Gast can be used in aerobic septic systems from 500G.P.D to 1000 G.P.D. or ponds up to 1 acre in size. The 0523 offers more consistent air flow over a diaphragm or piston pump and normally a longer life as well. these aerators can be rebuilt many times when the vanes wear down and no longer work.

The rotary vane design allows for easy maintenance as well as a long life. Rebuild kits are available for this product. This product can be expected to perform for five or more years before it will require a rebuild kit.
