Can the Gast Rotary Vane compressors be used for pond aeration?

Yes the rotary vane pumps work well for pond aeration applications. The AT05 can work in ponds as deep as 10 feet. The 0523 can work in ponds as deep as 15-18 feet.

Linear vs Rotary Vane...Which Should I Choose?

Linear diaphragm pumps are more energy efficient and much quieter than their rotary vane counterparts.

Rotary Vane pumps use significantly more power and create a lot more noise, but in some applications that require above 3 psi they will last much longer.

In most cases, linear and rotary vane units can be interchangeable. It is up to the end user to determine what is most important from the pros and cons listed above as to which is the best choice for their application.
