Aerodyne – DBMXL120-1250 – Septic Air Pump


The Aerodyne DBMX L 120 overcomes many problems with other aerators producing 100LPM or more.

• The outside dimensions are the same as a 150 or 200LPM pump. This helps reduce internal heat that destroys diaphragms and coils.

• It uses the same rubber diaphragm as the 200LPM pump. That reduces stretching of the rubber diaphragm and prevents repetitive stress fractures.

• It produces 46db of noise. That is between the level of noise of a library and a conversation at home.

• It consumes 1.9 AMPs (126 Watts) and produces 120LPM at 2.84PSI.

• A safety switch and thermostat protect internal components from diaphragm breaks or abnormal internal temperature buildup.


The Aerodyne DBMXL120-1250 is an excellent choice for 750 to 1,000 gallon per day aerobic septic systems of large homes.

Use diaphragm kit DBMXD150200 to replace diaphragms, head assembly, and check valves.
