    NFPA has published almost 300 codes and standards with the mission of preventing the loss of life and property. Topics include fire prevention equipment, extinguishing systems, inspection, residential and commercial dwellings, safety of flammable gases, and the very important National Electrical Code.

    • Technical Information

    N/A Gardner Denver meets the need
    The need was already there: Find a reliable way to completely eliminate any oil getting from the compressor into the delivered air stream. Gardner Denver met the challenge by applying new technology, new materials and new manufacturing techniques to our compressor design. Internal moving parts in the Gardner Denver Oil-less design are protected from wear without conventional lubrication. Crankshaft and rod bearings are lubricated by exclusive sealed, solid synthetic lubricants. Pistons move on alloyed heat-resistant filled PTFE guide and compression rings. The result is low maintenance, high durability and pure, oil-less air!

    Clean compressed air
    Gardner Denver has always been at the forefront of air compressor technology. Gardner Denver’s PureAir Series oil-less compressors are no exception. We offer 100% duty cycle, sealed anti-friction bearings and filled PTFE rings.

    Gardner Denver’s continuing program of product research and development assures that your Gardner Denver compressor includes the latest advancements in oil-less technology. We can design and build a system that meets your demand.

    Optional Features

    N/A A wide selection of configurations and options allow you to customize the compressor system to your specific needs:

  • Control Panel
  • Fusible Disconnect Switches
  • Automatic Tank Drain
  • Flexible Discharge Line
  • Vibro-Isolators
  • Vinyl-Lined or Galvanized Receivers
  • Water-Cooled Aftercooler
  • Remote Intake Air Filter/Silencer
  • High Temperature Shutdown/Lag Compressor Alarm
  • Air Dryer and By-Pass Piping
  • Downstream Filter Banks and Indicator Gauges

    Totally Dry Crankcase
    Designed to maintain continuous operation. Finned to maximize efficient heat transfer. Large cover provides easy access to internal parts for service.

    Pistons
    Patented design with “Iso-Temp” coating on top to isolate piston, rings and connecting rod bearings from the full heat of compression. Provides exceptional thermal heat barrier for extended ring life -10,000 hours or more!

    Piston Rings
    Designed for oil-less compressor service with three compression rings and two guide rings. Exclusive “O” ring pumper prevents axial movement of the guide rings and eliminates end wear. Formulated of filled PTFE material for long life and compatibility with the hardened nickel-plated, polished surface of the cylinder bore.

    Crankshaft
    Cantilevered crankshaft design provides superior balance and long life.

    N/A Air-cooled Aftercooler
    (Optional) Oversized, with ample reserve for cooling discharged air to within 5 - 10 degrees of ambient temperature. Enables air dryer to work at its highest efficiency.

    100% Duty Cycle Operation
    All models are rated for 100% continuous duty cycle at 100 PSIG for single-stage units and 175 PSIG for two-stage units.

    Cast-Iron Cylinders
    Permanently nickel-plated and hardened to resist wear and corrosion, even under extreme operating conditions. Smooth bore, polished finish, minimizes friction and reduces heat build-up for long ring wear life.

    Spring-isolated Base
    Eliminates need for special foundations. Compressor and motor are mounted on a common inner base plate. This inner base is mounted on vibro-isolation springs to absorb all vibration. Meets NFPA guidelines for medical air compressors (Over-and under-unit configuration uses elastomeric vibro-isolators).

    Valves
    Plated valve plates and reeds of highest grade Swedish steel extend operating life and durability.

    Bearings
    Long-lasting ball bearing design; 100% oil-less. 10,000 hour life on drive set bearings, 20,000 hours on main bearings.
