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 roller bearings located outside the compression chamber. Single width cylindrical roller bearings are used at the inlet end of the rotors to carry part of the radial loads.
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.
For aluminum oil coolers, do not use any cleaning solution that is not compatible with aluminum. Use of improper solution may result in damage to the cooler. Figure 2-1 – TYPICAL COMPRESSOR ROOM Minimum Air Flow* For Compressor And Cooling (cubic Feet/Minute) Air Cooled All Models 4800 cfm...
If the compressor unit base is raised above floor level, the space between the floor and the base bottom must be closed with solid material all around to prevent recirculation of hot air from the oil cooler end and over temperature operation.

Page 21
The compressor starts and stops automatically. Automatic restarting can cause injury or death. Open, lockout and tagout main disconnect and any other circuits before servicing the unit. The enclosure doors must be in place and fastened down to keep the compressor package from overheating when the compressor is running.
Page 22
Unit Hot (No warm-up period is required): Open the air service valve (customer furnished) between the main air system and the check valve on the package. Run for approximately one minute. The unit is equipped with a minimum (70 psig) pressure/check valve, no special procedure to maintain the unit reservoir pressure is required.
Page 23
Quick Start Guide Operation of the AirSmart controller is easy. Simply select a Target Pressure and then press the Run button to start the compressor, no other settings are required. The Target Pressure comes preset to 100 PSI from the factory. The Unload Pressure is preset to 110 PSI. If a different pressure setting is desired, the following steps can be used as a guide.
Page 24
To change the Target Pressure, press the Enter button to edit the value. OPERATION ADJUSTMENT TARGET PRESSURE 100 PSI (EDIT PARAMETER) A flashing cursor will appear covering the least significant digit in the Target Pressure value, use the Plus and Minus buttons to change its value.
CONTROLS & INSTRUMENTATION GENERAL DESCRIPTION The Gardner Denver rotary screw compressor is prewired with all controls, motor, and starter for the voltage and horsepower at the time of ordering. It is necessary only to connect the compressor unit to the correct power supply and to the shop air line.
CONTROL DEVICES Controller - This compressor unit features the "AirSmart" controller, which integrates all the control functions under microprocessor control. Its functions include safety and shutdown, compressor regulation, operator control, and advisory/maintenance indicators. The keypad and display provide the operator with a logical and easily operated control of the compressor and indication of its condition. The controller is factory adjusted for the compressor package, but allows tuning for specific applications.
Page 27
Never paint, lubricate or alter a relief valve. Do not plug vent or restrict discharge. Operation of the unit with improper relief valve setting can result in severe personal injury or machine damage. Ensure properly set valves are installed and maintained. Oil Level Gauge - This gauge is located on the oil reservoir and indicates the oil level.
Page 28
Reservoir Pressure Transducer (Figure 4-1, page 24) - This transducer is connected to the coolant system. Its signal is used to prevent loaded starts, monitor oil pressure, and to monitor the condition of the separator. Air Filter Vacuum Switch (Figure 4-1, page 24) - This switch is used to monitor air filter condition and alert the user if the filter requires service or replacement.
Page 29
Changing Minimum Pressure/Check Valve Seals Air/oil pressure will cause severe personal injury or death. Shut down compressor, relieve system of all pressure, disconnect, lockout and tagout power supply to the starter before removing valves, caps, plugs, fittings, bolts and filters. Be sure the unit is completely off and that no air pressure is in the oil reservoir.
Oil separated at the air/oil separator is sent via an oil return line through an orifice and back into the compressor. RECOMMENDED LUBRICANT – Gardner Denver compressors are factory filled with AEON lubricants. These lubricants are formulated to the highest quality standards and are factory authorized, tested and approved for use in rotary screw compressors.
Page 37
Specific AEON™ lubricants are recommended for use in this equipment. Other lubricants may cause excessive carryover or compressor damage. Do not mix different types of lubricants or use inferior lubricants. Check the decal on the oil reservoir for lubricating coolant specification. HIGH TEMPERATURE OPERATION - If the discharge temperature is sustained between 200°...
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 39
DRAINING AND CLEANING OIL SYSTEM Air/oil under pressure will cause severe personal injury or death. Shut down compressor, relieve system of all pressure, disconnect, lockout and tagout power supply to the starter before removing valves, caps, plugs, fittings, bolts and filters. Always drain the complete system.
Page 40
Compressor, air/oil reservoir, separation chamber and all piping and tubing may be at high temperature during and after operation. 1. Be sure the unit is completely off and that no air pressure is in the oil reservoir. 2. Disconnect, lockout and tagout the power supply to the starter. 3.
Page 41
Do not repeatedly restart the unit after high temperature stops operation. Find and correct the malfunction before resuming operation. All materials used in Gardner Denver compressor units are compatible with AEON 9000SP Lubricating Coolant. Use caution when selecting downstream components such as air line lubricating bowls, gaskets and valve trim.
Page 42
Machine should then be run normally; however, total run time after the initial change outs should be 50 percent of normal anticipated service life of the new lubricant. • Drain all lubricant from system, change filter and separator, and replace with full charge of the new lubricant.
OIL LEVEL GAUGE (Figure 5-4, page 42) - The oil level gauge indicates the amount of oil in the air/oil reservoir. Read oil level only when the unit is shut down and the air/oil mixture has separated. Add oil only when the oil level is in the bottom red range, below the white range on the gauge (you must use a flashlight).
Use only the replacement element shown on the filter tag or refer to the parts list for the part number. Use the following procedure to replace the filter element. Do not disturb the piping. Air/oil under pressure will cause severe personal injury or death. Shut down compressor, relieve system of all pressure, disconnect, lockout and tagout power supply to the starter before removing valves, caps, plugs, fittings, bolts and filters.
Page 45
COMPRESSOR OIL COOLER - The cooler fan is mounted on the compressor motor shaft; air is exhausted through the oil cooler and away from the unit. Do not obstruct air flow to and from the oil cooler. Allow a minimum of two (2) feet (.6M) clearance around the cooler. Keep both faces of the cooler core clean for efficient cooling of compressor oil.
Page 46
NOTICE A sudden drop of zero pressure differential or sudden heavy oil carryover may indicate a ruptured element. Inspection - After removal of separator element, shine a light inside the element to reveal areas of heavy dirt or varnish deposits or breaks (ruptures) in element media. Removal of Oil Separator For Inspection or Replacement: Air/oil under pressure will cause severe personal injury or death.
Page 47
9. Grease the O-Ring on the separator element and install the separator into the housing. 10. Replace the O-Ring between the minimum pressure/check valve and the air/oil separator housing. 11. Replace the sealing kit in the minimum pressure/check valve. After the assembling of the valve, leave about .08 inch gap between the nut and the cover of the valve.
SECTION 6 AIR FILTER Figure 6-1 – AIR FILTER STANDARD DUTY AIR FILTER (Figure 6-1) - Replacement instructions are given in the following sections: Compressor, air/oil reservoir, separation chamber and all piping and tubing may be at high temperature during and after operation. The air filter element can not be cleaned or reused.
Page 49
Install new air filter element and the air filter cover. Open the air service valve. Filter Element Life - The element should be replaced if visual inspection indicates an accumulation of dirt, or a rupture, crack or pin holes in the pleated media. Inspection should be done by placing a bright light inside the element.
SECTION 7 BELT DRIVE Proper drive belt tension and alignment are provided at the factory, however, good practice dictates checking the drive alignment and tension after shipment and before initial start-up. Sheaves should align straight across the front with a straight edge. The best tension is just enough tension to keep belts from “squealing”...
Page 51
Once proper alignment has been obtained, lock the sheave in place on the motor shaft; then the jack bolt lock nuts must be tightened. One set of nuts is tightened down against the base to lock the jack bolts in place.
SECTION 8 MAINTENANCE SCHEDULE SERVICE CHECK LIST – Air Filter - Operating conditions determine frequency of service. See “Air Filter,” SECTION 6, page 47. Motor Lubrication - Refer to SECTION 2, page 16. Every 8 Hours Operation Check the reservoir oil level - add oil if required. See Section 5, page 35.
