Cleaning
Keep the coolers clean to maintain efficiency. On air-cooled compressors:
• Stop the compressor, close the air outlet valve and switch off the voltage.
• Cover all parts under the coolers.
• Remove the side baffle that encloses the fan compartment.
• Remove any dirt from the coolers with a fibre brush. Brush in the direction of the cooling fins.
Also remove any dirt from the fan with a fibre brush.
• Then clean with an air jet in the reverse direction to normal flow. Use low pressure air; if necessary the
pressure may be increased up to 6 bar(e) .
• If it is necessary to wash the coolers with a cleaning agent, consult Atlas Copco.
• Remove the cover used during cleaning.
• Mount the side baffle that encloses the fan compartment.
