Application Scenarios

- Centralized air supply for down-the-hole (DTH) drills in large open-pit coal and metal mines.

- Full-face TBM or drill-and-blast air supply for deep, long tunnels (railway, highway, water conservancy).

- Mega-construction projects such as large dams, ports, and nuclear power plants.

- Energy projects including oilfield fracturing and large pipeline laying.

- Specialized construction projects requiring large, centralized air supply.

Customer Frequently Asked Questions (FAQ)

Q: For a heavy-duty model like KDHP, are the service intervals the same as for standard portable compressors?

A: No, the requirements are stricter. Due to heavier loads and harsher environments, the maintenance schedule is typically shorter. For example, the oil change interval and replacement intervals for the diesel fuel filter and air filter may be half or less (e.g., 250 hours vs. 500 hours) compared to standard models. The Heavy-Duty Maintenance Schedule manual provided with the machine must be strictly followed to ensure equipment life and reliability.

Q: Will the FAD decrease at high altitudes? How is this addressed?

A: Yes, some decrease occurs. The power of both the diesel engine and the screw airend decreases as altitude increases and air thins. The KDHP series offers an optional "High-Altitude Booster Package," which includes a higher-flow turbocharger, a high-altitude optimized airend, and a matching cooling system. This package significantly reduces performance loss and meets construction requirements at altitudes of 3000–5000 meters.
