Product Introduction

The 185CFM portable diesel screw air compressor is one of the small series of the mining diesel screw air compressor machine,witch has 41kw diesel power. Due to its small size and compact structure, it is suitable for working environments where frequent movement is required. Equipped with a single-stage screw motor, it enables the compression process to be completed in one step. It also offers an exhaust volume of 5 m³/min and a working pressure of 8 bar, providing stable power for pneumatic tools.The small air compressor with wheels can perform well in narrow environments.

details features of small air compressor on wheels

1. Air filter system: The patent maintenance-free centrifugal air pre-filter filter out more than 90% of the dustand impurities,make filter maintenance and change cycle prolong 5 times.
2. High efficient single-stage air end: The structure is simple and reliable, and the maintenance cost can be reduced by over 30%; with the adoption of an efficient rotor profile design, the volumetric efficiency exceeds 92%; the overall weight is reduced by 15%.
3. Modulation Control: Based on air demang,the modulation valve will control the inlet air capacity and diesel engine RPM to minimize the fuel consumption . Its features maximum energy saving.
4. Control panel: easy to control; high water temperature alarm , high pressure alarm ,high discharge air temperature alarm and high RPM alarm are all part of it's features.
5. Diesel Engine: 185CFM portable diesel screw air compressor Using well known diesel engine like Cummins, Xichai and Yuchai. Has the capacity to achieve an outlet pressure of 7bar, 8bar and 10 bar.This ensure superior performance and reliability of the compressor.
6. Cooling fan: Larger cooler and fan design to ensure maximum cooling especially for the extreme operating environment.
7.Single-door design:Lift-off cabinet panels are easily removable for maintenance access. Spin-on oil filter and air/oil separator element minimize service downtime.
8.Two-wheel design: small air compressor on wheels has the characteristic of lightweight,highly flexible, capable of being manually towed, suitable for small-scale operation areas.
9.Lubrication system: Forms an oil film between the screw rotors, reducing direct metal-to-metal contact friction and preventing rotor binding or wear.
quality assurance of diesel screw air compressor machine
1.Strict contract auditing involved all departments to assure the feasibility of each order.
2.Process design and validation before bulk production.
3.Strictly control on all raw and auxiliary materials
4.Qualified WPS and professional welders guarantee welding quality.
5.Inspect and test products before shipment
6.Regular training for inspection staff
