Flexaust has manufactured durable, long lasting, flexible hose and ducting solutions for industrial and commercial applications for 80 years. Our hose products are used in applications involving air, dust, fume and lightweight materials. It all began in 1938 when Arizona mining engineer Harold Hersey filled a desperate need for the mining industry by developing the first flexible hose system to vent fumes and bring fresh air to hard working miners. The transition from mining to industrial applications was sparked by the heavy construction activities of World War II. After the war, Flexaust continued to grow by supporting industry with hose and ducting that would improve the workplace environment.
