Carbon and varnish can form in compressor oils. These deposits block the flow of lubricant and cause excessive wear and failure of moving parts.
Contamination of the fluid can allow the formation of acids, causing extensive internal corrosion. Water may be condensed decreasing the fluid’s lubricity. Fluid in rotary compressors does much more than lubricate.
During the compression process, it acts as a sealant in the airend which is important for maximum efficiency. The fluid also absorbs much of the heat of compression to cool the airend and reduce the temperature of the compressed air. It’s not enough that a compressor fluid lubricates well, it must stand up to the heat, pressure and contaminants that are present in every air compressor. 1.8.1 General Information KAESER synthetic lubricants should be stored in a protected location to prevent contamination. Do not re-use drums; flush and send to reconditioner. Although the KAESER synthetic is not highly flammable, it will burn. While KAESER synthetic compressor oil is less flammable than equal viscosity mineral oils, it cannot be classified as a fire-resistant fluid.
It has a flash point above 460F. Since the user has total control over the conditions of the compressor lubricant, he assumes total responsibility for its safe usage. Material Safety Data Sheets are available for each lubricant from your KAESER authorized distributors. Regardless of the lubricant selected, the KAESER Sigma lubricants will separate readily from water. If condensate occurs it can easily be removed. Let the compressor sit so that any water can drain back to the separator tank and separate to the bottom.
See chapter 9.14 proper draining procedure. 1.8.2 KAESER Fluids KAESER COMPRESSORS has several lubricants available that are specially formulated to match these demands.
They feature excellent lubricity, outstanding demulsibility (ability to separate from water), and long life. RECOMMENDED KAESER LUBRICANTS SIGMA DESCRIPTION LUBRICANT. MAXIMUM RECOMMENDED CHANGE INTERVAL. First Oil Change Subsequent Oil Change M-460 ISO 46 Semi-Synthetic Lubricant 2,000 Hours 4,000 Hours S-460 ISO 46 Synthetic Lubricant 6,000 Hours 8,000 Hours Oil changes may need to be more frequent depending on ambient conditions. When high ambient temperatures or dirty conditions are present, oil changes may be necessary every 1,000 hours (4,000 hours for synthetic) or even shorter intervals. Oil change intervals required should be determined through periodic oil analysis.
M - SERIES SEMI - SYNTHETIC LUBRICANTS - M-Series SIGMA compressor fluids are the highest quality petroleum lubricants. M-460 is specially blended to provide reliable performance in KAESER screw compressors. 1 - 3 Technical Specification S- SERIES SYNTHETIC LUBRICANTS -S-Series SIGMA compressor oils are formulated from the most advanced synthetic lubricants. These ”synthetic” lubricants begin as high quality petroleum feed stock. They are then refined, processed and purified into fluids with very consistent molecular structure. These oils are carefully blended to produce extremely consistant lubricants with superior properties. SIGMA synthetic lubricants feature all the advantages of both PAO and diester fluids.
S-460 lubricant is recommended for compressors operating in ambient temperatures between 40F and 105F. Specialty KAESER LUBRICANTS - S-680 lubricant may be used when ambient temperatures are always between 70F and 105F. FG-460 synthetic hydrocarbon based food grade fluid is designed for use in rotary screw compressors in the application where incidental food contact may occur with the discharge air. This fluid meets the requirements of the FDA Regulation 21 CFR §178.3570 and is USDA H-1 approved.
FG-460 is approved for canning, food packing, meat and poultry processing and other applications where incidental food contact may occur.

When high ambient temperatures or dirty conditions are present, oil changes may be necessary every 1,000 hours (4,000 hours for synthetic) or even shorter intervals. Oil change intervals required should be determined through periodic oil analysis. Compatibility of KAESER Sigma Lubricants All the above listed KAESER Sigma lubricants are similar to mineral oil in their compatibility with paints, seals, gaskets and hoses. The typical precautions are required when changing over from mineral oil to KAESER synthetic hydrocarbon based lubricant. Never mix lubricants of different types or brands.
When switching from mineral oil to a synthetic oil, the plant’s system materials must be re-evaluated. Certain plastics are not compatible with synthetic oils. The following is a partial list of acceptable and not recommended materials: 1 - 4 Technical Specification ACCEPTABLE Viton High Nitrile Buna N Teflon Epoxy Paint Celcon Neoprene SBR Rubber Low Nitrile Buna N Oil Resistant Alkyd Nylon Delrin Acrylic Paint Lacquer Polystyrene Attention!

Signs and labels of reference may not be removed or rendered unreadable.
These instructions must also be observed: - Allow no open flames and flying sparks at the place of installation. Ensure that sparks or high temperatures cannot cause fire or explosion if welding is carried out on or near the compressor. Ensure that the compressor unit can breathe clean intake air that contains no damaging components. Do not allow the maximum ambient temperature to be exceeded (see chapter 1.6), otherwise special measures must be agreed between the manufacturer and the customer. 2 - 8 Safety 2.3 - Carry out oil changes according to the service manual. Use only oils recommended by the manufacturer.
Do not mix cooling oils of different types. The operating temperature stipulated must be kept to and checked constantly to avoid condensate in the oil circulation. If maintenance work is carried out on any part of the oil circulation system, top up the oil in the oil separator tank to the maximum level afterwards, run the compressor for a short period and keep it under constant observation. Check the oil level again and top up with oil to replace the oil taken up by the piping and the cooling system.
Use the filter cartridge of the oil separator tank only as long as the pressure drop across the filter is less than the 14.5 psi specified. 2017 gmc sierra 2500 slt. Check constantly. This machine is not explosion -proof. It may not be operated in areas in which specific requirements with regard to explosion protection are applied. Electrical Power Supply Attention!

Have the the start -up carried out by an authorized KAESER service technician. 4 - 13 Construction and Operation 5 Construction and Operation 5.1 Principle of Compression The stationary compressor package is fitted with a single stage, oil-injected airend. The two rotors, the driven male rotor and the female rotor, both mounted in antifriction bearings, are fitted into the airend. As the rotors rotate, air is drawn into the upper side through the inlet port and is compressed on the lower side.
The oil that is injected into the lower side absorbs heat generated by compression, prevents metal to metal contact between the rotors, seals the rotors and the housing from each other and also lubricates the antifriction bearings. The compressed air and oil mixture leaves the airend via the discharge port. 6 4 1 Drive shaft 2 Oil injection 3 Discharge port 5.2 5 1 4 5 6 2 3 Male rotor Female rotor Air inlet port Brief Description The compressor block is driven by an electric motor via V-belts. An oil separator cartridge is fitted into the oil separator tank allowing practically oil free compressed air supply. The control system of the compressor package ensures that compressed air is generated within the set pressure limits.
Safety devices protect the compressor package against failure of important systems through automatic shut -down. The fan ensures ventilation of the compressor package and sufficient cooling air for the air-cooled oil cooler and air aftercooler.
5.3 Pipe and Instrument Flow Diagram (P & I Diagram) (see following pages) 5 - 14 Construction and Operation 5 - 15 Construction and Operation 5 - 16 Construction and Operation Pressure DUAL Control p max p min 1 Full load Motor power 5.4 2 3 t1 4 5 t2 Idle Standstill Time In DUAL Control (combined idle and start -stop) the compressor normally runs at full -load, idle or standstill. The controller regulates the compressor package between full - load and idle. If the compressor package runs in idle for longer than the preset period (1) to (2), for example t1 = 6 min, the drive motor is stopped completely (2).
When the lower switching point p min (3) is reached the compressor package is automatically started again. Pressure rises to the upper switching point p max (4), and the compressor package switches to idle. If the pressure falls again to, for example, p min (5) within a shorter period (4) to (5), then the compressor is automatically switched from idle to full-load.
The idle period is dependent on the maximum motor starting frequency.
