Additional Information

Additional Information

 N/A Because compressed air is an essential utility, dependability is an essential compressor quality. If your compressor goes down, it can hurt your reputation-and your bottom line. Gardner Denver™ reciprocating compressors are proven units, known for their reliability over decades of use. In addition to dependability, you want a compressor that is user-friendly. Gardner Denver™ comes through again, with a wide selection of configurations and options designed for trouble-free operation.

You can’t beat a Gardner Denver™ compressor!

Proven Design

Proven Design

 N/A Today’s Gardner Denver™ Reciprocating Compressors are the product of decades of design and development. In fact, we introduced the first single-stage compressor in 1919 and have continuously improved its design through innovations in material, production techniques and quality control.

Proven Dependability

Proven Dependability

Select the Configuration that Matches Your Application

Select the Configuration that Matches Your Application

 N/A With many models from which to choose in both single-stage and two-stage compressors, we can match your exact needs. These configurations, combined with a wide choice of options, provide all the components for a customized installation. They are available in both R-Series splash-lubricated and PL Series pressure-lubricated models.

Tank-Mounted Air Compressors

Tank-Mounted Air Compressors

 N/A Available with horizontal or space-saving vertical tanks, two-stage air compressors compress air to a higher pressure than single-stage compressors.

Base-Mounted Air Compressors

Base-Mounted Air Compressors

 N/A Designed for installations where air tanks are remotely located.

Duplex Air Compressors

Duplex Air Compressors

 N/A For extra air delivery when you need it without wasted space. Plus the flexibility of single operation, alternating between compressors, or duplex operation to meet high air demand.

Gasoline or Diesel Engine Powered Air Compressors

Gasoline or Diesel Engine Powered Air Compressors

 N/A Truck and utility bed mounting design makes these compressors ideal for fleet and field service. Ideal for applications where electricity is not available.

Select the Options That Match Your Needs

Select the Options That Match Your Needs

 N/A Many options are available to help you develop a Gardner Denver™ compressor package that exactly matches your specific operating requirements.
  1. Magnetic Starter
    For thermal overload protection, a starter is required for units 3 horsepower and above. Starters available as mounted or unmounted. (Included as standard on most models.)
  2. Air-Cooled or Water-Cooled Aftercooler
    The factory mounted, heavy-duty, air-cooled aftercooler effectively reduces up to 65% of the moisture from discharged compressed air.
  3. Automatic Tank Drain (Pneumatic)
    Automatically removes water from air receiver upon demand. Eliminates the need for manual purging.
  4. Vibration Isolators
    Isolates the compressor unit from the foundation or floor. Reduces noise and protects the unit from any out-of-level floor situation that could cause vibration and damage.
  5. Low Oil Level Monitor
    Low Oil Level Monitor shuts down the unit when oil levels are below an adequate level. Prevents the unit from restarting if oil levels are not at an adequate level.
  6. Refrigerated Dryer
    Cools compressed air to a 33 ºF - 39 ºF dew point, eliminating additional downstream condensation in the air line. Normally, a dryer should be used in conjunction with an aftercooler.
  7. DPR Control Panel
    The Microprocessed Duplex Relay Panel was created for controlling a duplex air compressor package. The controller includes visual maintenance and shut down alarms.
  8. Gardner Denver™ Compressor Lubricants
    AEON™ lubricants are blended specifically for Gardner Denver™ compressors for use in harsh compressor environments. They are sourced from extremely stable base stocks and enhanced with carefully selected additive packages to provide long life and superior protection. AEON™ lubricants are suitable for a variety of applications and are available as a mineral oil, synthetic or food-grade synthetic. Available in 55-gallon drums, five-gallon pails, one-gallon bottles and one-quart bottles.
