  • Page 9: Section 1, General Information

    SECTION 1 GENERAL INFORMATION Figure 1-1 - COMPRESSOR CYCLE COMPRESSOR - The rotary screw compressor is a single stage, positive displacement rotary machine using meshing helical rotors to effect compression. Both rotors are supported between high capacity anti- friction bearings located outside the compression chamber. Roller bearings are used at the inlet end of the rotors to carry part of the radial loads.
  • Page 10 AIR FLOW IN THE COMPRESSOR SYSTEM Figure 4- 8 page 52 - Air enters the air filter and passes through the inlet unloader valve and on into the compression chamber where oil is injected into the air. After compression, the air/oil mixture passes into the oil reservoir where most of the entrained oil is removed by velocity change and impingement and drops back into the reservoir.

    SECTION 2 INSTALLATION GENERAL - On receipt of the unit, check for any damage that may have been incurred during transit. Report any damage or missing parts as soon as possible. Do not electric weld on the compressor or base; bearings can be damaged by passing of current.

  • Page 15: Figure 2-1 - Typical Compressor Room

    For continuous efficiency, the cooler cores must be periodically cleaned with either vacuum or compressed air. If wet cleaning is required, shield motor and spray on a mild soap solution and flush with clean water. NOTICE Coolers are aluminum; do not use any cleaning solution that is not compatible with aluminum.

  • Page 16: Figure 2-3 - Cold Weather Installation

    ENCLOSURE - The compressor, electric motor, oil cooler and after cooler are mounted inside the enclosure. Service panels are provided for maintenance access. Be sure to allow enough space around the unit for the panels to be removed. Any of the enclosure panels may be removed by opening the latch and lifting it up slightly.
  • Page 17 When the unit must be installed in an outdoors installation and/or exposed to ambient temperatures below freezing (32 F, 0 C), contact Gardner Denver for recommendations. When using a Total System with a compressed air dryer option, refer to Section 10 for details. Unsheltered (outdoors) installation shall be avoided. Installation next to a heated building may be sufficient to keep the compressor package room above freezing temperature and thus avoid operational complications.

  • Page 18: Figure 2-4 - Electrical Wiring Sizing - Fs Variants

    When piping two or more rotary screw units on a common discharge line, each unit shall be isolated by the check valve in the unit discharge line. If a rotary screw and a reciprocating compressor are piped to a common discharge line, an air receiver must be located between the two units.

    For instructions on checking the oil and the proper oil level, refer to “Oil level gauge”, SECTION 5 see page 53 Do not mix different type oils. Standard Unit is shipped filled with Gardner Denver AEON 4000 lubricant which is suitable for the first 4000 hours under normal operating conditions. Other AEON lubricants are available.
  • Page 21 Failure to properly ground the compressor package could result in controller malfunction. Rotation - Check for correct motor rotation by jogging the motor. See “Maintenance, Motor Jog” menu in Controller Operating and Service Manual. Compressor drive shaft rotation must be: For Direct-Drive compressor, counterclockwise when facing the compressor shaft.
  • Page 22 10. Target Pressure - This is the package discharge pressure that the controller would maintain. For fixed speed units, a pressure rise of 3psi above the target value would result in an unload action. For flow modulating units (e.g., variable speed or inlet throttling), a pressure rise above the target would result in flow modulation.
  • Page 23 The controller has an automatic start/stop sequence built in. You do NOT need to close the air service valve. Closing the air service valve on start-up or prior to shutdown will cause rapid cycling, and could cause a high pressure shutdown.
  • Page 24 Quick Start Guide For your convenience, the following excerpt from the Controller Operating and Service Manual is presented to assist in programming the basic operating parameters. However, we strongly recommend you read the Controller Operating and Service manual before attempting operating the compressor package.

  • Page 25: Section 4, Controls & Instrumentation

    CONTROLS & INSTRUMENTATION GENERAL DESCRIPTION The Gardner Denver rotary screw compressor is pre-wired with all controls, motor and starter to match specific voltage and horsepower as ordered.

OIL SPECIFICATIONS - The standard factory fill compressor lubricant is Gardner Denver AEON 4000, a superior semi-synthetic blend of petroleum stock and various protective additives, suitable for year-round operation.
  • Page 53 Before draining, adding, or changing the lubricant oil in the compressor, be aware of the following hazards associated with these tasks: Air/oil under pressure will cause severe personal injury or death. Shut down compressor, relieve system of all pressure, disconnect, tag and lockout power supply to the starter before removing valves, caps, plugs, fittings, bolts and filters.
  • Page 54 All materials used in Gardner Denver compressor units are compatible with AEON 9000SP Lubricant. Use caution when selecting downstream components such as air line lubricating bowls, gaskets and valve trim. AEON 9000SP Synthetic Lubricant is not compatible with low nitrile Buna N or acrylic paints.
  • Page 55 ADDITION OF OIL BETWEEN CHANGES must be made when the oil level is below the minimum level of the sight glass as read while the unit is completely off and blown down, and the foam has settled out. Be sure the unit is completely off and that no air pressure is in the oil reservoir. Disconnect, tag and lockout the power supply to the starter.

    Operating conditions and the appearance of the drained oil must be surveyed and the oil change intervals planned accordingly by the user. Gardner Denver offers a free oil analysis program with the AEON lubricants, and we recommend a sample be sent in at 100 hours on a new unit.
  • Page 58 Optional Element. If the compressor is used in a predominantly cold (<32ºF, 0ºC) and/or humid environment, proper oil viscosity and avoidance of water vapor condensation in the oil system may be achieved by using a higher setting (158ºF, 70ºC) thermostatic element. Consult Gardner Denver for details.

    4. If coupling gap did not exceed 2-3mm beyond its nominal limit of 24/25.8mm, loosen M8 set screw on motor coupling hub and move to close gap to nominal limit. If coupling gap is still within its nominal limits of 24/25.8 mm, verify that each M8 set screw fixing the hub to the shaft is tight. If either hub set screw is loose, apply a locking compound to its threads and tighten to 10 N-m torque.
