Gast 0523 Rotary Vane Applications

The Gast 0523 Rotary Vane septic air compressor is used on 500-750 GPD rated NSF Class 1 Standard 40 aerobic treatment systems (ATUs). The Gast 0523 compressors are also commonly used in pond aeration applications. With their ability to run continuously at 10.0 psi, they can pump to depths of 15-18 feet. This is much deeper when compared to the linear diaphragm pumps which can only push air to depths of 6 to 8 feet.
