Introducing the CycloBlower VHX — A World First Blower Technology

The demand for energy savings is higher than ever. As energy costs continue to rise and significantly impact manufacturer’s bottom lines and profitability, the demand for more efficient technologies grows. Thankfully, innovation is in our DNA at Gardner Denver.  Much like DNA, the rotor design of our blowers dictate what they become.


Gardner Denver is excited to announce the launch of its new CycloBlower VHX. By adding a variable helix to our patented helical screw design, unmatched levels of blower performance and efficiency is achieved. This new patented rotor design incorporates faster internal compression and a significantly larger discharge port to eliminate losses, thus creating premium efficiency and higher turndown capability. Gardner Denver’s blower evolution continues with the world’s first variable helix blower technology, the CycloBlower VHX.
