Inovair (Accessible Technologies Inc.)

Inovair, a division of Accessible Technologies Inc. based in Lenexa, Kansas, has manufactured integrally geared centrifugal blowers and compressors in the USA for over three decades. The company states it is the only manufacturer of high-efficiency blowers made in the USA, as referenced in a November 2023 EPA Request for Information. Their wastewater aeration product line spans the IM-10 at 15 to 50 horsepower, IM-20 at 25 to 150 hp, IM-30 at 40 to 400 hp, IM-40 at 100 to 350 hp, and IM-50 at 300 to 600 hp, complemented by the IO-10 at 15 to 50 hp and IO-20 at 25 to 100 hp, along with custom control systems. For aircraft ground support, Inovair produces the 1200GS, 1600GS, and 2200GS blower packages for preconditioned air supply, plus forced-air deicing blowers and air start compressors. General industrial models include the Inovair 1200, 1600, and 2200 bare blowers plus the IE series from 25 to 125 hp for pneumatic conveying and combustion air applications. All Inovair blowers feature non-contact oil film bearings and deliver pulsation-free output at 75 to 85 decibels. The company reports 10 to 40 percent energy savings compared to positive displacement and multi-stage centrifugal designs, with documented case studies showing payback periods frequently under two years and one example saving 42,000 dollars annually after aeration blower replacement. Pressure capability ranges from 4 to 55 psi. A branch office operates in Mill Valley, California, and products are distributed through a representative network.
