Product Description

1. Double screw
2. German air end
3. Low noise
4. Competitive price
5. Energy saving

Every model has a corresponding frequency conversion compressor, which controls the air flow by changing the rotational speed of motor, making the air output and electricity consumption smoothly vary synchronously with the different air flow. When the air use quantity falls, the air supply decreases and so does the electricity consumption for energy conservation. For capacity ranging from 2 to 60m3/min and discharge pressure from 0.5 to 1.3Mpa, there are corresponding models available to customers with different requirements. In addition to that frequency conversion air compressors have the same good quality as other models; The quality frequency converter will further better their result of energy conservation. with the help of the PID regulator disposed in a frequency converter, it can start up smoothly, causes little impact on the power grid and generates great low current. When the air use decreases, the compressors enter the sleeping status, saving considerable energy. Moreover, digital to analog conversion is highly accurate and the integration design features few fault points.

Life of air compressor
Rotors are asymmetric in profile, backed up by ball bearings and roller bearings; Operate at a low speed, thereby low in abrasion and maintenance expenses, air end are long service life. Helical gears can produce axial force to kill some acting force, which reduces the load of the bearing of air end.
More reliable operation

with frequency conversion soft start, it avoids grid impact, self-engendered mechanical impact, and negative factors of lasting high speed operation of the air end. Without the participation of a contactor, it prevents point contact failure. Setting desired pressure at discretion, and maintaining constant pressure
Users can set pressure between 3-14 bars at their discretion, without changing the gear of belt.

When air use increases, the unit increases air output through automatic acceleration of rotational speed to avoid a fall in pressure and ensure air supply at constant pressure. When air use decreases, the unit increases air output through automatic deceleration of rotational speed to avoid a rise in pressure and ensure continued air supply at constant pressure.

Efficiency and energy conservation
Thanks to the variable speed control technology, the capacity of compressors can be perfectly combined with the air use of users, which downright avoids the unloading power loss. In intermittent air use, the zero load of soft start avoids the peak of current and torque. Therefore, the speed of the units can be adjusted for limitless times. Truly realizing steeples speed change and minimizing the loss of reactive power. Without the pressure burden in excess of 2 bar, the unit can save energy directly by 14%. That is because every 1 bar operating pressure reduced can save energy by 7%
