Page 3: Safety Cautions
SAFETY CAUTIONS Please read this operation manual carefully before installation and operation This series are high pressure air compressor. It compresses atmosphere air go to pressure 0.3/0.8Mpa, 45/110psi, after be purified and separated by the filter and separator. It discharge clean air accords to GB18435-2001 breathing air standard. It is widely be used for breathing of diving and fire fighting;... - Page 4 ￭ Check the electric voltage in nameplate is same as your local electric supply ￭ Check the lubricate oil has been put in before running ￭ Increase rated pressure setting is forbidden ￭ There is potential danger of pipe burst or connect fitting blow off under high pressure, please avoid body too near compressor when it running ￭...

TECHNICAL DATA SCU80P / Gasoline Engine Driven Diving air compressor Charging Rate: 250L/min; 8cfm Suction pressure: atmosphere Working pressure: 0.8MPa， 8bar, 110psi Media: air No.of stage and cylinder: 1 Engine power: 5HP / HONDA Cooling: air Driven: belt driven Shout down：Automatic stop by pressure switch Pressure indicate：Gauge... - Page 6 STRUCTURE 3.1 Main Components 3.2 Working process Atmosphere air is sucked into cylinder of the compressor, and compressed to reach 0.3Mpa/0.8MPa 40/110 psi pressure, through regulator with water separator , then purified by filter. Discharge clean air for diving breathing. 3.3 Pump unit The pump block unit is composed of crankcase, crankshaft, cylinder, piston, intake and discharge valves, connect rod , bearing etc.
- Page 7 3.4 Gauge & safety valve The pressure gauge is installed in final stage of the compressor to display discharge pressure. The safety valve is installed at the place of discharge to take the overpressure protection. If the discharge pressure is higher than preset value, the safety valve will open and release pressure.
