Screw

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. 

Features:

• Patented, highly-efficient 3×5 variable helix screw rotor profile 
• Food-grade PTFE (Polytetrafluoroethylene) coated rotors 
• 3 discharge port designs matches the most efficient performance to your application requirements
• High pressure capability up to 36 psi
• O-ring sealing
• Helical Timing Gears
• Unique Dual Splash Lubrication with eccentric slinger ring
• Force Feed Lubrication optional for applications under 20 psi, required for applications over 20 psi 
• Inpro/Seal Premium Oil Seals 
• Mechanical Seals also available for gas applications
• Piston Ring or Graphite Air Seals
• Robust Ductile Iron Shaft
• Available as bare blower for upgrading existing packages
