water lubricating oil-free screw air compressor
1) 100% OIL-FREE :
TUV Class 0 Oil-free Certificate
Clean air:purified by water,without dust
2) At Least 30% Energy-saving :
Single screw air compressor theoretically doesn’t have any clearance volume
The water used as a lubricating medium also seals gap inside the compression chamber,and enables high efficient operation at low speeds(about 3000r/min)
Using water as a cooling method keep compressor Ideal isothermal compressio
Variable frequency inverter(Permanent magnetism variable frequency)
3) Environment protection :
No discharge of three wastes; Low vibration and less noise
4) Reliability :
Simple and balance structure and the temperature of the unit is less than 50℃,so maintenance period more than 50000 hours
Lowest cost and maintenance (Only air filter and water filter < $500)
5) Low noise
Superior dynamic balanced system can effectively control the vibration source
The motor and screw are directly connected without any rotation gear to cause gear noise
Sound absorbing materials are also used in the equipment shell to reduce noise
2. Advantages
(1) Stable Pressure
The variable speed air compressor adopts PID for precision speed adjustment. Changes in the air amount of
the system will be automatically tracked. The compressor will supply air at a constant pressure, which is the
preset desired pressure plus or minus 0.1bar, to reduce power consumption.
(2) Variable Flow Control
Adopt inverter to drive the compressor can adjust the rotation speed of the motor in real time according to
the actual air compression. In case of high air consumption, the pressure remains unchanged, but the
speed compensates automatically to meet the supply needs. When the air consumption is low, pressure
is maintained constant and speed is automatically reduced to supply compressed air which is just enough.
(3) No Current Impact during Starting
The air compressor is started via invert. The maximum starting current is 1.2 times the rated current for
power frequency start. Hence, our variable speed air compressor exerts little impact on the grid during
starting. It enjoys reduced stress and consequently prolonged service life.
(4) High Economical Efficiency
Throughout the operating life of the air compressor, energy costs account for most of all costs. However,
by using VSD, energy consumption is reduced by 30%.Therefore, the energy cost saved by a variable
speed air compressor for three years is roughly equivalent to purchase price of the unit.
