Coal Mining Portable Screw Air Compressor

Advantages
Safe, High Efficient Design of Coal Mining Screw Portable Compressor.

Main Features
1. portable screw air compressor can be used in coal well or where there is coal gas, reducing pipeline from the ground to the well and saving pressure loss of long pipeline.
2. Such kind of coal mining screw compressor adopts German main unit, advanced structure and small difference of 5:6 gear shape, thus it features small back-flow loss, 10%~12% more efficient than 4:6 gear shape, saving 25% electricity and is of high accuracy and stable operation.
3. portable screw air compressor for coal mining employs complete set of Austria HOERBIGER airflow control system with stable reliability.
4. With 0 to 100 load adjustment function, such coal mining screw compressor can change drive consumption with the change of the actual use of the airflow.
5. Safe and Reliable Use
portable screw air compressor has the protection function of explosive proof, over-load, short circuit and electric leak; and is equipped with protection device upon over heating, empty filter congestion; triple protection of safety valve to prevent overloaded pressure.
6. Such portable screw air compressor makes use of advanced oil gas separator to control oil content in compressed air below 5Pppm.
7. Such kind of coal mining screw compressor is mounted with highly efficient wind cooling wing plate cooler.
