Product Description

Gast AT05 Rotary Vane Septic Air Pump:
The Gast AT05 Septic Aerator is the industry work horse. It produces little noise, about as loud as a conversation at home or the office. That’s very different from older model rotary vane pumps.

The AT05 lasts far longer because, unlike linear pumps, it doesn’t use rubber diaphragms that wear out within 3 years. This rotary vane pump uses nickel plated rotors and a unique coating inside the pump that reduces wear. Gast added a built-in fan to cool the pump during hot, southern summers. Over all, this septic aerator should last up to 10 years.

The AT05 is designed to run at 5PSI, but it will overcome system pressure up to 10 PSI for a while. That is 4 times more back pressure than linear pumps can do. If diffusers in the tank are clogged, the AT05 can overcome the back pressure until your maintenance provider replaces the diffusers. That means the oxygen continues to flow to aerobic bacteria in the tank and your system won’t go septic.

Repair kits are easy to install. The AT05 is designed for ease of maintenance. Whether you want to change the air filters or perform a complete re-build, a few hand tools are all you need. You can do a complete re-build with a Gast OEM kit in less than 1 hour.

To rebuild/repair pump use kit K882.

    This was the exact pump I needed with the lowest online price. I ordered Friday morning and it was delivered to my doorstep Saturday afternoon. I was also impressed with how well it was packaged. I couldn’t be happier with my purchase.

    I shopped around for this particular model and found that Septic Sewage Pumps had the best price. The employee was very helpful when I called to check on delivery status. Was delivered on time and installed.

    Everything went well until I started to install the nut caps on the rubber vibrating feet. One of the nut caps was not threaded.

    The aeration pump shuts down from overheating every hour. Why is this happening. The last aeration pump ran continually for 23 YEARS.

    This was a replacement for another unit I was using that after 10 years plus was getting too noisy. I can barely hear the new one
