Built for the Sewage Aeration industry, the AT05 rotary vane pump is easy to install, rugged, and provides clean, life sustaining air to wastewater treatment systems. This low noise, low vibration aeration pump only produces 59db of noise; about as loud as a conversation at home or in your office. The AT05 works especially well in systems requiring more, consistent flow and higher pressures.

Other features include:

  • Thermal overload protection safeguards the motor against high temperature damage;
  • Easy to service vanes and filters extend the life of the unit and maximizes uptime;
  • Totally Enclosed Fan Cooled motor protects against the summer heat; and
  • Internal and external inlet filters prevent contaminants from entering your system.

Gast OEM repair kit includes everything you need to repair an AT05, including vanes, gaskets, and filters.

Buy an external, air intake filter assembly to replace one that is clogged or deteriorated.
