The Gast 0523 rotary vane compressor has been used in Canadian ponds and lakes for many years, providing a high volume of air pressure for pond aeration.

The outer air filter of this compressor has 2 built-in air filters making the vanes last longer, plus the vanes can be replaced making the Gast 0523 a good long-term investment in pond aeration.  The size of the compressor fits well into a small well-ventilated pump house near the water’s edge. Alternatively, it can be installed farther from the pond and use ½” tubing to pump air to the pond.
