MDotor conrnecits with the air-end male rotor directly by the coupling,  eliminating the nveed teo use nthe gear box, this design greatly improves the  
transmission efficiency. Roteck producs 1:1 energy transfer direct driven  
screw air compressor.
Roteck screw air compressors are stable and reliable, with minimal  
vibration, offering continuous smooth compressed air to users.
The compressor design temperature is according with the high temperature  
(46℃) and high humidity situation, this design avoids the possibility of  
shutdowns caused by the high temperatures.
Silent case type, low noise & low vibration. Intelligent control system,  
Roteck are mechanical and electrical integrated screw air compressors.

VSD Screw Air 
SCoamvprees syoor ur energy 
cElecotricisty ctosst is o!ver 80% of the air compressors operating cost. The electricity cost of 
 the air compressor is 40% of the factories total electricity cost. When your screw air  
compressor is unloading, it continues to consume electric power but gives you nothing 
 in return.
To save your energy cost, Roteck integrates the Variable Speed Drive (VSD)  
technology into the air compressor which greatly saves energy and protects the 
 environment.
Use VSD
Arerage save

Actual air demard Energy consumption Power waste
Why choose
ROTECK Variable Speed Screw Air 
Compressor?
On average 35% energy savings during air demand  
fluctuations, Inverter controls the motor to deliver the 
 exact air volume.
No compressed air wasted during unload, no air leakage  
C O M P R E S S  O R problem when in normal operation.
VSD startings lows down the impact of electric network  
when starting.
Reduce the leakage rate due to the lower system 
 pressure.
Perfect match between the air compressor and the 
 inverter.
Fitted with “VSD” and “Fixed speed” selector switch,  
unit can be reverted to normal fixed speed operation if  
the inverter is faulty or under repair, not affect the  
07 production efficiency.
