The Hiblow 40-1070A Septic Air Pump has an 8-year lifetime, which is the best in the business. It is the smallest available unit for 500 gallon-per-day (GPD) aerated septic systems and is the most energy-efficient option for its capacity. This model can also be used to aerate water gardens and small ponds. Unlike the Hiblow 40-0110, the 017A comes with a pre-installed alarm, so you don’t need a separate panel with a pressure switch. There are three modes of operation: Run, Mute, and Test. Run mode is for normal operation, the Test mode activates both visual and audible alarms to test for function, and Mute will eliminate the sound, but leave the visual alarm active.
