The DBM80-175 linear septic air pump produces 80LPM of air and includes a high and low pressure alarm. This is formerly a Gast DBM-series septic pump. This pump only emits 51db of noise, about the same noise as a conversation at home. The DBM80-175 is a solid, less expensive replacement for your 500 gallon aerobic system.
The alarm actives when air pressure rises over or drops below functional level to warm users to check the system in time. There is RUN, TEST and MUTE function included.
Low pressure alarm
Alarm actives when air pressure drops below functional level at 61.8mbar(0.89psi) and reset at 68.67mbar(0.99psi).
To replace the diaphragms in a DBM80-175, use diaphragm kit SSP10DFS.
