Much like DNA, the rotor design of our blowers dictate what they become. Gardner Denver is excited to announce the launch of our 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.
