2 stage air compressor screw air compressor 


2 stage air compressor

Under normal conditions
Save 15 % more energy
than a single level.

Two stage compression adopts Isobaric ratio is set for interstage pressure

Reduction of compression work by secondary air compression

Air end structure
Adopts large rotors. Lower speed. Lower running noise.
Case design,including two independent compression units, Improve the
installation precision.
Helical gear drives directly.each rotor got excellent speed ratio.

Advantages of helical gear
Helical gear meshing good, smooth transmission, low noise.
The high coincidence degree of helical gear reduces the load of each
pair of gear and increases the load capacity of gear
The helical gears do not produce a minimum number of roots cut.

Ordinary straight gears enter into meshing at the same time along the tooth width, thus producing shock vibration noise and unstable transmission. Helical cylindrical gear is superior to straight gear and can be used for high speed and heavy load. The transmission torque of helical gear is large, the start is stable
and the transmission ratio is fine.
