High Pressure Air Compressor DJ-5.5/250 for Pressure Instrument Leak Testing 250bar

These units are oil-lubricated piston machines; oil is separated and filtered through the intercooler, aftercooler and separation system. If your test process requires oil-free air, please tell us and we will propose a suitable configuration.

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, high ambient temperature, or valve leakage causing backflow. Abnormal oil consumption is typically worn piston or scraper rings, or an over-high oil level. These are directional checks; final diagnosis depends on model and duty conditions.

The standard supply is 380V / 50Hz / three-phase. Other voltages and frequencies, and other site electrical requirements, can be confirmed at the time of order.

We are recruiting agents, distributors, suppliers and project partners worldwide. Policy highlights: direct supply from our own production base with no intermediary margin; competitive supply prices that leave margin to partners; and industry-exclusive agency available for qualified partners. Please contact us with your market and target industries.

Yes. Pressure class, flow rate, drive method, voltage and frequency, cooling arrangement and air treatment can all be configured, and minor, full and design-based customization are available. Final technical parameters are confirmed before the order is placed.
