Gast Rotary Vane air pumps are constructed out of quality materials to ensure longevity and reliability. Whether you’re replacing your old rotary vane pump or purchasing one for the first time, you can’t go wrong with one of these products.

Rotary Vane Advantages

There are several reasons to consider using a rotary vane-style pump, including their unrivalled construction quality and quiet operation. Additionally, this design eliminates the need for sliding parts and therefore increases energy efficiency. This also means that there is no lubrication added to the pump, so all of the expended air will be perfectly clean.

Finally, this product pumps air at a consistently smooth rate, allowing it to excel in situations where a constant air supply is needed. The 1023-101Q-G278 Model This relatively new model comes in at ¾ HP and is designed for long hours of continuous operation. It also features 10 CFM (Cubic Feet per Minute) openflow and 10 psi max pressure, making this pump reliable for lower pressure applications. Solid cast iron housing makes this pump remarkably durable.

Similar models have lasted for up to fifteen years with relatively little maintenance involved compared to diaphragm-style pumps. This air pump is an ideal choice for you if you have no interest in replacing expensive parts in the next decade. A replacement rotary vane should last you much longer than a traditional air pump. If you can’t afford for your pump to fail during rigorous around-the-clock operation, go with a Gast Rotary Vane model.
