Product Description

High Efficiency BMVF7.5 Best Portable Permanent Magnet Screw Air Compressor

Oil injected screw air compressor has become the mainstream of air compressor development in the world. It has extremely superior and reliable performance. It has small vibration, low noise, high efficiency and few vulnerable parts. It has incomparable performance advantages of piston compressor (under the same exhaust pressure). The precise coordination between the male and female rotors and between the rotor and the main engine shell reduces the back- flow leakage and improves the efficiency; Only the rotors are meshed with each other, and reciprocating motion without cylinder, which reduces the source of vibration and noise; The unique lubrication method brings many advantages:

1. With the pressure difference generated by itself, lubricating oil is continuously injected into the compression chamber and bearing to simplify the complex mechanical structure.
 

2. The injected lubricating oil can form oil film between the rotors, and the primary can take secondary rotor to rotate, Without the help of high precision synchronous gear.
 

3. The injected lubricating oil can increase the air tightness.
 

4. The lubricating oil absorbs a lot of compression heat, so even if the compression ratio reaches 16, The head can still be controlled below the carbon deposition and degradation temperature of general lubricating oil, There is no friction between the rotor and the outside of the machine due to different expansion coefficient.
 

5. Lubricating oil reduces the noise caused by high frequency compression.
 

6. A small amount of oil into the compressed air, pneumatic tools have a certain lubrication.
