S&N Airoflo, Inc.

S & N Airoflo, Inc. has supplied floating brush rotors to the municipal and industrial sector for over 20 years. These aerators are engineered to deliver better efficiency, higher O2 transfer and mixing performance, with less horsepower. Power savings of 30% to 60% have been documented in virtually every type of wastewater treatment application. S & N Airoflo brush rotors can be unloaded, have the floats attached, and placed into position to operate in a few hours.

Airoflo's unique cupped shaped blades and aggressive rotor design transfers oxygen below and above the water surface increasing O2 efficiency. With a direct pumping rate of 2100 gpm/Hp, it is a highly effective mixer for both deep and shallow basins. Horizontal mixing produces a large area of influence reaching corners and sides. Short circuiting can be eliminated.

Airoflo supports their products with professional design calculations, drawings and recommendations for new installations, retrofits and upgrades of older facilities. Their units are available in stainless steel or galvanized models, from 3 to 20 HP, with many unique design features for high performance, long life and simple, predictable maintenance.

Reduced Maintenance Costs
Airoflo’s machines incorporate high quality motors and gear reduction drives, with the best engineered rotor and blade design in the industry. There are no bolt-on blades to replace or damage the rotor. Their maintenance free UHMW wastewater lubricated bearings and bi-metallic bushings protect the rotor shaft, require no external source of lubrication, and will provide years of maintenance free operation.

Airoflo’s reputation for providing excellent treatment and product support has made them the leader in the application of floating brush rotors for wastewater treatment.

Save energy by applying S&N Airoflo's low speed, low HP mixers, with high pumping rates and directional flow.


  • Anoxic mixing for denitriciation in the activated sludge process.
  • Enhances the performance of your floating aerators in applications where mixing dominates.
  • Improves the performance of facultative lagoons by reducing algael growth, odors, short circuiting, and build-up of sludge and floating debris.

S&N Airoflo, Inc.

Lagoon Applications:

  • 3, 5 and 10 HP models - in hot dip galvanized or stainless steel.
  • Direct flow rates from 8,000 to 20,000 GPM, depending on HP and RPM.
  • Wastewater lubricated bearing.
  • Significantly lower capitalization costs.
  • Much higher pumping and mixing rates than fractional HP solar powered systems.
