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, the exchange interval will be determined.

Before removing the valve, depressurize the compressor. See also section Problem solving

The safety valve (SV) can be tested on a separate air line. If the valve does not open at the set pressure stamped on the valve, it needs to be replaced

An additional safety valve is fitted on tank mounted versions. The valve can be tested on a separate air line. If the valve does not open at the set pressure stamped on the valve, it needs to be replaced

WARNING! No adjustments are allowed. Never run the compressor without safety valve;

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

Refrigeration dryers of ID type contain refrigerant HFC

When handling refrigerant, all applicable safety precautions must be observed. Please be specifically aware of the following points

Contact of refrigerant with the skin will cause freezing. Special gloves must be worn. If contacted with the skin, the skin should be rinsed with water. On no account may clothing be removed

Fluid refrigerant will also cause freezing of the eyes; always wear safety glasses

Refrigerant is harmful. Do not inhale refrigerant vapours. Check that the working area is adequately ventilated

Be aware that certain components such as the refrigerant compressor and the discharge pipe can become quite hot (up to 110 °C - 230 °F). Therefore, wait until the dryer has cooled down before removing the panels

Before starting any maintenance or repair work, switch off the voltage and close the air inlet and outlet valves;
