Having worked in some of the world's most intense manufacturing and production facilities, we've seen how frustrating it can be to pay someone else to come in and clean. Or shut down production to ensure overhead dust accumulation doesn't become a problem. That's exactly why we designed the SonicAire fans. These durable, energy-efficient fans are specifically designed to keep fugitive dust from collecting and becoming a problem. Our BarrierAire technology keeps dust from ever reaching your overhead spaces, eliminating costly, time-consuming cleanings.
