How to Choose the Right Air Compressor?
-Determine Whether the KSCY-400/14.5K Portable Rotary Screw Compressor Fits Your Jobsite Needs
As a manufacturer specializing in construction machinery and air compression systems, we understand that every job comes with its own set of challenges-whether it's the work environment, equipment demands, or operational workflows. When developing the KSCY-400/14.5K diesel-powered portable screw air compressor, we focused specifically on the real-world conditions often encountered in the field: no access to a fixed power supply, frequent equipment relocation, the need for a stable, continuous air source to support pneumatic tools, and reliable performance in hot, dusty environments.
This machine's structural design and core functions are built to address these conditions directly. If you're working under similar circumstances, the KSCY-400/14.5K could be the right fit for your operation.

Why Choose the KSCY-400/14.5K Portable Rotary Air Compressor?
Built for Remote and Demanding Outdoor Jobs
Powered by a diesel engine and mounted on a towable chassis, the KSCY-400/14.5K is suitable for field operations without access to electricity. It suits applications like road and railway construction, mining, water conservancy, and remote drilling, providing a reliable, continuous air supply for heavy-duty pneumatic tools.
High Pressure and Airflow Capacity
With a rated pressure of 14.5 bar (1.45 MPa) and airflow of around 400 cfm, this air compressor can power multiple air tools simultaneously. It's well-suited for high-demand equipment such as deep-well drills and pneumatic rock breakers, maintaining stable output even in tough environments.
Fuel-Efficient and Easy to Maintain
Equipped with a fuel-efficient engine from Cummins or Yuchai, it features auto-adjusting intake and RPM based on air demand, reducing fuel waste. The direct-drive system has fewer wear parts, while filters are easy to replace, lowering downtime and operating costs.
Reliable in Harsh Conditions
An oversized cooler and large fan ensure stable performance in hot or dusty conditions. Built-in protection alerts for high temperature or pressure help prevent breakdowns, while the filtration system protects internal components from debris and dust.
Maintenance Schedule
| Interval | Key Maintenance Tasks |
|---|---|
| Every 50 hours/week | Clean the air filter, check the oil quality and level, and tighten all hose and pipe connections. |
| Every 250 hours/month | Replace the fuel filter, remove dust from the cooler, and inspect the tires and trailer brakes (for trailer-mounted units). |
| Every 500 hours / Quarterly | Change compressor oil and oil filter; check the intake valve and safety valve for proper function. |
| Every 1000 hours / Semi-annually | Deep-clean the cooling system; listen for abnormal noise from the airend; calibrate warning devices (temperature/pressure). |
| Every 2000 hours / annually | Replace the oil-air separator element and fully tighten all structural components. |
