Features & Benefits

Innovative Air End Design

• Patented taper rotor design optimized for efficiency
• Stainless steel coating robotically applied to rotors in both 1st and 2nd stages provides superior corrosion resistance and durability
• Patented PTFE-free rotary coating designed for long life
  • Coating specifically engineered to help ensure rotor tolerances remain consistent — maximizing discharge capacity over the life of the unit
• Stator housing coated to provide additional corrosion protection

Patented Oil Mist Remover

• An environmentally friendly solution to recapture gearcase oil mists
  • Helps ensure oil-free air compression
  • Recycles gearcase oil to reduce oil top offs needed
  • Helps promote a cleaner production environment

Motorized Isolation Valve 

• Automatically closes compressed air discharge when DSP shuts off — protecting the compressor from condensate backflow

Package Designed to Optimize Energy Efficiency and Oil-Free Operation

• VSD models feature a Patented No Inlet Valve Design
  • Eliminates negative pressure at unloading — helping increase shaft seal reliability
