Feature&Benefit |
Feature |
|
Benefit |
Pressure selection and control |
Easy pressure setting |
Flow selection and control |
The working pressure and airflow rate can be adjusted according to the size of air consumption without wasting any diesel |
The twin-screw rotor is directly connected with the diesel engine by a highly flexible coupling |
Outputting more air with less energy consumption, featuring high reliability, longer service life, and low maintenance cost. |
The two-stage air filtration system |
The total efficiency of air filtration reaches 99.8% ensuring the compressor to not be infringed by dust and dirt particles and longer service life of the engine |
High-temperature resistance design |
Able to run for a long time under extreme cold or hot temperature from -20ºC to 50ºC |
One-button start, clear operational parameters |
Operators don't have to go through long-term professional training, and unattended operations can be achieved. |
