Gast AT05-101-215DX Rotary Vane Septic Air Pump


When in the market for a new Septic Air Pump, it is important to keep a few features in mind: longevity, maintenance, and loudness. If you want a quiet Air Pump that needs little maintenance, but will last for years, the Gast AT05-101-215DX is likely for you. It is the septic air pump of choice for professional installers that want to give customers a long, trouble-free septic air pump.

What makes the Gast AT05-101-215DX stand out, is the way it compresses air. Until diaphragm pumps, it is not sensitive to back pressure. The unique carbon vane puts a film down on the counter face, so the material is wearing against itself. This allows the vane to wear at a rate of just a thousandth of an inch per year. This allows the unit to typically work for 8 to 10 years without any significant issues. That means your unit can make over 7 billion rotations before having to be rebuilt. To keep this intuitive product up and running, you have to ensure the compressors has clean filters.

It is recommended you clean the top filter every four to six months. You should also replace the internal filters every year. If the filters are dirty, dust will enter the septic air pump. This dirt and dust will strip the film layer away. Without that important film layer, the Gast AT05-101-215DX will break down faster, and will likely need to be rebuilt long before the 8 to 10 year mark.
