Air Compressor

screw air compressor

The system uses a 0-100% displacement stepless adjustment. When the gas consumption is reduced, along with reduced displacement, the motor current is also reduced; when no gas, air compressor running empty, empty for too long automatic shutdown;

Characteristics of our products

Efficiency and energy saving

*With the variable speed control technology, the capacity of compressors can be perfectly combined with the air use of users, which 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%.

 

More reliable

*The frequency conversion machine starts smoothly and can avoid the peak current which might burden your whole power supply.

*Avoiding the negative factors from constant high speed running.

*Lowing the possibility of system leak by setting the surpass pressure under 2 bar.

The displacement pressure can be changed easily and provide stable constant pressure air

*The displacement pressure can be set between 3-14 bar without gearbox or belt.

*A pre-set stable constant pressure will be output in a range of ±0.1bar 

*When the system has a high demand of air, the machine will run faster and keep providing stable pressure air.

*When the system has a low demand of air, the machine will run slower and keep providing table pressure air.

 

== Energy saving and environmental protection ==

1.Takes advantage of variable-speed drive technology, extend life of screw air compressor.

2.Compressor with frequency conversion, three years later save the money more than the price of the screw air compressor .

3.More energy saving, the better environmental protection. Note: Generally speaking ,the screw air compressor without inverter, we can add it according to your requirement.

== Sophisticated structure and a good interpersonal interaction ==

1.The reasonable structure design, save space and convenient for the maintenance .

2.Humanized multi-language panel design(Chinese,English,Spanish,Russian,etc),different languages can be private custom.

 == Quality supervision, and packing ==

1.To strive for zero failure rate, all machines have pass many strict tests before they go out.

A.1 hour full load operation to test  electric air compressor efficiency and free air deliver per min.

B.2 hour full load operation to test air compressor spare parts performance and its temperature sensors.

C.0.5 hour full load operation to test air compressor noise level db.

D.Continue running 24 hours a day to test air compressor’s reliable performance before they go out.

2.Multiple protective packaging to reduce rough handling damage.

3. Unpacking can be used.
