What S&N Airoflo does
S&N Airoflo, Inc. is a privately held Mississippi corporation founded in 1989 and headquartered in Greenwood, Mississippi, that designs and manufactures floating brush rotor (FBR) aerators and complementary mixing equipment for municipal and industrial wastewater treatment. Its core products — the 1600 Series and 2200 Series Floating Brush Rotors, the Maxflo FDM floating directional mixer, the BIOFLO attached-growth rotating biological contactor, and the NR'G MI$ER controls-integrated system — are engineered with a proprietary cupped-shaped blade geometry, offset blade spacing, and UHMW wastewater-lubricated bearings designed to deliver high oxygen transfer (3.0 lb O2/HP-hr clean water) and pumping rates (2,100 gpm/HP) with 30-60% documented energy savings versus conventional vertical and fixed-rotor aerators. Equipment is sold in 3 to 30 HP configurations in stainless steel or galvanized construction and is available with accessories such as the EZ Access platform, Extended Vertical Shields, and TF32 gear reducer upgrades.
The company's go-to-market is direct sales to municipal water utilities, government entities (including state corrections departments), and industrial operators in food and beverage, textile, and winery wastewater applications, supported by technical papers, case histories, and design application worksheets. Pricing is quote-based under EXW terms with multi-year purchase agreements, and S&N provides professional design calculations, drawings, and recommendations for new installations, retrofits, and upgrades. The company has approximately 300 cumulative installations across the U.S. (with documented projects in Mississippi, Alabama, Texas, North Carolina, Georgia, and California) and Mexico, and in August 2025 it was acquired by Axius Water as a strategic addition to that acquirer's nutrient removal portfolio. The company maintains two named leaders — President R. A. Norris and Director of Operations Todd Nester — and operates with 11-50 employees.
