(over 5 m (16,4 ft), more than one bend, filter cartridges, screens, etc.), please contact your technical adviser. CompAir screw compressors are rated for ambient temperatures and cooling temperatures of +2°C (35,6°F) to +40°C (104°F). In the case of temperatures other than the above limiting values, please consult your technical adviser.
