Recently we looked at some of the benefits of switching to Oil-Free compressed air.  Moving to an Oil-Free compressor can have a significant impact on your cost of ownership, but like most capital expenses, you’ve got to do your research before you buy.  Let’s take a look at the Kobelco KNW Series and see what unique features set it apart from the competition.

  • Heavy Duty Air End Design – a patented, high-efficiency super rotor profile. Rotors, shafts and compression housing all have a PTFE coating to protect against corrosion and wear.  Thrust balance pistons on each stage provide maximum air end life.  These are not found on competitive models.
  • Pre and Post Lubrication of Gears & Bearings – an independent motor-driven gear pump provides lubrication prior to start up, during operation and shutdown. A unique feature of the Kobelco KNW Series that increases gear and bearing life.
  • Heavy Duty Input Bull Gear – input bull gear is supported on each side along with a labyrinth type seal used on the drive end. Competitors use an overhung design as well as lip seals, which are prone to wear and leakage.  The KNW design ensures a long operating life and eliminates oil leaks.
