Atlas Copco Oil-Injected Rotary Screw Compressor GA18FF TM 18.5KW fix speed

WARNING! Always apply all relevant Safety precautions.

Always drain the compressor oil at all drain points. Used oil left in the compressor can contaminate the oil system and can shorten the lifetime of the new oil.

Never mix lubricants of different brands or types as they may not be compatible and the oil mix will have inferior properties.

A label, indicating the type of oil filled ex factory, is stuck on the air receiver/oil tank.

If the compressor is equipped with an Energy Recovery unit, also drain the oil in the heat exchanger.

Run the compressor until warm. Stop the compressor. Close the air outlet valve and switch off the voltage.

Depressurize the compressor by opening the manual drain valve(s). Wait a few minutes and depressurize the air receiver/oil tank by unscrewing oil filler plug (FC) just one turn to permit any pressure in the system to escape.

Open the filler plug (FC) and drain the oil by opening the valve at the bottom of the oil tank (OT).

Also remove the drain plug near the element outlet. Close the drain valve and fit the plugs after draining.

Check that condensate is discharged during loading

Check the service indicator on the DD and PD filters (if provided);

Check the electrical connections. Tighten if required according to values indicated on service diagram

Check the condition of the air intake hose of the air filter

On Full-Feature units: clean condenser of dryer and replace the filter mesh of the drain

Atlas Copco's Roto-Foodgrade Fluid is a unique high quality synthetic lubricant, specially created for oil- injected screw compressors that provide air for the food industry.

This lubricant keeps the compressor in excellent condition.

Roto-Foodgrade Fluid can be used for compressors operating at ambient temperatures between 0 ̊C (32 ̊F) and 40 ̊C (104 ̊F)

If the compressor is regularly operating in ambient temperatures above 35 °C (95 °F), oil lifetime is reduced

Select the ambient temperature range

Select the element outlet temperature range

Based on the selected temperature ranges, follow the appropriate exchange interval

Ambient temperature - up to 25 °C -- Element outlet temperature - up to 90 °C: Exchange interval is 4000 Hours / 1 Year

Ambient temperature - from 25 °C up to 35 °C -- Element outlet temperature - from 90 °C up to 100 °C: Exchange interval is 3000 Hours / 1 Year

Replace DD and PD filters or whenever the pressure indicator points red (if provided)

Minimum wall thickness as specified in the instruction book must be respected

Local regulations remain applicable if they are more strict
