Dg-1.5/250 High Pressure Air Compressor, 3626psi for Pipeline Pressure Test

The motor rating is DG-1.5/250 kW. Please provide your site voltage, frequency and phase (for example 380 V / 50 Hz / 3-phase) so we can confirm the motor and starter configuration. Foundation, ventilation and cooling water requirements are stated in the installation manual supplied with the unit.

T/T (commonly 30% advance, balance before shipment or against copy of B/L), L/C at sight, and other methods negotiable for large orders. Payment can also be protected through the Made-in-China platform. Final terms depend on order value and cooperation conditions.

The complete unit carries a 1-year warranty. We supply Chinese and English operation manuals and video tutorials, plus remote video guidance for installation and commissioning. Key wear parts such as filters, piston rings and seals are kept in long-term stock for quick dispatch, and urgent enquiries are answered within 24 hours.

Routine maintenance covers inspection and periodic renewal of the intake filter, compressor oil and filter elements. Recommended oil change intervals are 1,000-2,000 hours depending on model and duty cycle. Refer to the manual supplied with your unit for the exact schedule and oil grade.

Low delivery is usually caused by a blocked intake filter, valve leakage or a damaged valve plate, worn piston rings, line or joint leakage, or insufficient speed from low voltage or frequency. High discharge temperature usually points to a dirty cooler, insufficient or over-warm cooling water, high ambient temperature, or valve leakage causing backflow. Abnormal oil consumption is typically worn piston or scraper rings, or an over-high oil level.
