Gardner Denver Introduces CycloBlower VHX Series Blowers

Gardner Denver has unveiled the new CycloBlower VHX Series of rotary screw blowers, which feature a patent-pending variable helix 3 x 5 helical screw rotor profile for a high level of reliability and performance, as well as more efficient turndown capabilities across a across a wider range of flows and speeds when compared to other technologies. The first available model of the CycloBlower VHX Series is the 100CDL300A with additional sizes to follow.

Gardner Denver VHX

The CycloBlower VHX is designed with a patent-pending variable helix 3 x 5 helical screw rotor profile to deliver reliability and performance.

Gardner Denver introduced the CycloBlower rotary screw technology in the 1950’s and reimagined it in 2015 with a patented 3x 5 fixed rotor profile that improved efficiency, expanded the pressure capabilities up to 36 psig and widened application of the technology. Now it has leapfrogged its rotor design with the patent-pending variable helix 3 x 5 helical screw rotor profile found in the CycloBlower VHX.

The CycloBlower VHX design integrates a variable helix pitch with its patented screw rotor profile, increasing efficiency in generating faster internal compression allowing for larger discharge porting that minimize air losses. In addition, it allows the achievement of energy savings up to 35% when compared to comparable sized technologies.

Available with three different discharge port options, the CycloBlower VHX optimizes efficiencies based on the pressures and performance of the application.  It’s built with a robust ductile iron shaft tested for strength, helical timing gears for smooth operation, Inpro/Seal® oil seals for superior leak protection and other premium parts backed by an industry leading, extensive warranty. The new blower is built at Gardner Denver’s manufacturing facility in Sedalia, Missouri.
