Select the Options That Match Your Needs (To Request Information)
Many options are available to help you develop a Gardner Denver compressor package that exactly matches your specific operating requirements.

1. Magentic Starter
For thermal overload protection. Required for units 3 horsepower and above. Starters available as mounted or unmounted.
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°F-39°F 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.

Other Options

N/A

  • Power Monitor that shuts down unit in the event of single phasing, low voltage or phase reversal
  • Constant Speed Control which prevents excessive motor start/ stop cycles while saving energy
  • Dual Control will allow the compressor to run either in start/stop or constant speed mode
  • NEMA 4 rated parts available
  • Alternate voltages and TEFC, ODPHE, TEFCHE Electric Motors

  • Gardner Denver™ Reciprocating Compressors...The Value Leaders.

    N/A
    At Gardner Denver, air compressor systems are our only product. We know and understand the application of our products in many different operating environments. Our goal is to provide you with the compressors that fulfill—and exceed—your expectations and requirements.

    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!

    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

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

    Bare Compressor Pumps
    Gardner Denver pumps provide dependable service for industrial applications, OEM applications, and pump replacement. The rugged pump design assures reliability and long maintenance intervals.

    Receivers
    Receivers are ASME approved and include a pressure gauge, pressure relief valve, drain valve and service valve.

    Warranty

    N/A
    Compressor Pump Warranty
    Each new Gardner Denver Assembled Unit has a five (5) year warranty on the compressor pump only, against defects in materials or workmanship under normal use and service, from the date of installation or sixty-six (66) months from the date of shipment by Gardner Denver or a Gardner Denver distributor, whichever may occur first.

    The five-year extended warranty covers parts and labor and is prorated over the five years as follows:

    Year One — 100% coverage
    Year Two — 90% coverage
    Year Three — 80% coverage
    Year Four — 70% coverage
    Year Five — 60% coverage

    Head valves are warranted for Year One only. Gardner Denver makes no warranty on components and/or accessories furnished to Gardner Denver by third parties, such as electric motors, gasoline engines and controls. These are warranted only to the extent of the original manufacturer ’s warranty to Gardner Denver. Electric motors must be equipped with thermal overload protection to have warranty consideration. The extended five-year warranty will apply to ASME air receivers if they are installed on rubber vibro isolator pads or approved equivalent.

    5 Year Electric Motor
    Any Gardner Denver package purchased after January 1, 2003 built with a Baldor electric motor are warranted for 60 months from start-up or 63 months from shipment. Other manufacturer’s motors furnished due to customer request or special requirements carry the motor manufacturer ’s warranty.

    Package Warranty
    Gardner Denver warrants each new air compressor package to be free from defects in material and workmanship under normal use and service for a period of one year (12 months) from the date of installation or 15 months from the date of shipment by Gardner Denver. Units manufactured in Canada have a pump and package warranty for two (24 months) years.

    Limited Warranty
    Warranty shall not apply to any equipment which has been subjected to misuse, neglect or accident, nor shall it apply to any equipment that has been repaired or altered by any person(s) not authorized by Gardner Denver. Failure caused by lack of proper maintenance is not covered by warranty. In no event shall Gardner Denver be liable for consequential damages or contingent liabilities arising out of failure of any compressor or part to operate properly. When a compressor pump or component is changed or replaced during the warranty period, the new/replaced item(s) is warranted for only the remainder of the original warranty period. Complete warranty details are included in compressor operating manual.

    U.L. Standards
    Gardner Denver, in common with other major, industrial compressor manufacturers, does not market compressors which are U.L. listed. In general, U.L. is concerned with electrical components that may be utilized on compressor units, rather than a complete compressor package or system. All electrical components used on Gardner Denver compressors are U.L. listed. Each component – motor, starter, pressure switch, control panel – carries a U.L. identification mark on the nameplate or inside the electrical enclosure cover. The mark will be the letters “UR ” reversed (as if held up to a mirror), indicating the item is “recognized” by U.L. On tankmounted units, the air receiver tank and tank pressure relief valve are ASME Code. The tank carries a National Board Registration number which appears on a stamped, metal plate welded to the tank.

    All units are built to ISO 9001 standards.
