For more than 60 years, Gardner Denver has provided the original Helical Rotary Screw Blower. Our CycloBlower utilizes a 2x4 rotary screw profile, making it a highly efficient, screw blower that provides quality and dependability throughout multiple applications. The CycloBlower H.E. technology has improved upon that original design with a 3x5 screw profile that allows it to reach pressures of up to 36 psi and 36 psi. We did not stop there though! We took the innovation to the next step and created the variable helix profile of the CycloBlower VHX. With our CycloBlower, CycloBlower H.E., and CycloBlower VHX designs, you can be sure that we have utilized the best of the best components, to provide you with a durable, high-performing, and energy efficient blower to fit a variety of industrial applications.
