Gast rotary vane septic air pumps are quiet, reliable pumps designed to protect against internal corrosion and excessive noise. With their internal sound suppression the units won’t disturb you and their pulse-free high flow air make them ideal for providing your aerobic septic system with a consistent, steady air flow.

Your pump has two internal filters and you should plan to clean them every six months and replace them once a year. After years of operation, expect the carbon vanes will begin to show signs of wear or, in extreme cases, may shatter. Worn or damaged blades will cause the unit to lose pressure and result in reduced airflow.
