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
- Environmentally friendly solution to recapture gearcase oil mists
- Helps ensure oil free air compression
- Recycles gearcase oil to reduce oil topoffs 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
