As the orbiting scroll goes from No. 1 to No. 4 position the size of the symmetrical crescent-shaped compression chambers is gradually reduced, compressing the air contained within. This is then discharged through the central exhaust port.
- In BUMA Scroll type air compressor, it has absolutely different compression room from bearing parts so there is a minimum possibility of inflow and outflow of oil in case there is any problem or damage on the air compressor
- There is no gear lubricant because BUMA scroll type air compressor use V-belt driven.
- Specialized composition of BUMA oil-free scroll air compressor realizes 10,000 hours or 4 years maintenance period. It has long life span, low noise and low level of vibration that gives customers a special and additional value.
- Low Vibration
- There is very low changing torque in Oil-free Scroll Air compressor comparing with Reciprocating Air compressor, so it realizes very low vibration.
- There is another benefit in low changing torque: Strong start ability, which makes start and stop function in a limited movement on the condition of operation.
- Compact and Elaborate
- Due to low changing torque, no need much inertia force at the point of start-up scroll type air compressor and also, it doesn’t require big size of belt and crankcase which reduces size of air compressor.
- Comparing with the size of normal 3.7 kW reciprocating type air compressor, the size of scroll type can be diminished to 64%.
- Multiple installation in one main body
- Several scroll units which have low vibration and superior start and stop function can be installed simultaneously in one unit of main body so it can be configured for satisfying the requirement of back up function and it can conserve energy in variable situation.
- Low Noise
- Noise level of scroll type air compressor is much less than reciprocating type air compressor, which make it possible to be installed on/in the noise restricted area.
- Class 0 Oil-free Scroll type air compressor
- It is totally separated between compression chamber and bearing so there won’t be any oil leakage in case of break-down.
- Germany “ Class 0 (ISO 8573-1:2010)” Certificate
- Compressed air purity classes for total oil
