Average weight ... 21.3 kg (47 lb)Number of cylinders ... 2Bore size ... 69.85 mm (2.75 inch)Stroke ... 47.5 mm (1.87 inch)Displacement at 1250 rpm ... 16.1 CFMFlow capacity at 1800 rpm and 125 PSI ... 10.5 CFM Maximum recommended rpm ... 3000 RPMMaximum transient pressure of the inlet line depends on boost pressure. Maximum pressure depends on system pressure setting. Maximum discharge governor pressure depends on the system restriction. ... 1296 kPa (188 psi)The discharge line must transmit high pressure air from the air compressor to the air reservoir. In the reservoir, the high pressure becomes available for the air brake system. If restrictions exist, the discharge line could have an effect on the life of the air compressor. Restrictions in the discharge line will cause the air compressor to have extremely high peak pressure. The compressor will overheat.The temperature at the exhaust port of the discharge line of the air compressor shall not exceed 204 °C (400 °F).The application of downstream devices such as an air dryer needs to be installed properly in order to avoid premature problems with the air compressor. Refer to the manufacturer's instructions for these products.Coolant flow Minimum coolant flow at 600 rpm per minute ... 1.9 L (0.5 US gal) Minimum coolant flow at 2000 rpm per minute ... 6 L (1.6 US gal) Recommended average coolant temperature ... 88 °C (190 °F) Maximum transient coolant temperature ... 127 °C (260 °F)Maximum inlet air temperature ... 121 °C (250 °F)Minimum ambient temperature ... -40 °C (-40 °F)Maximum coolant temperature ... 130 °C (266 °F)A heat shield is required if the air compressor is located within 76.2 mm (3 inch) of an exhaust pipe. A heat shield is required if the air compressor is located within 76 mm (3.0 inches) of a turbocharger.Lubrication Minimum oil pressure at idle speed ... 100 kPa (15 psi) Maximum oil pressure at maximum speed ... 450 kPa (65.3 psi) Maximum temperature at oil inlet ... 130 °C (266 °F) Minimum inside diameter of oil supply line ... 3.2 mm (0.12 inch)Minimum inside diameter of discharge line ... 12.7 mm (0.50 inch)
