Pet Bottle Plant Blow Compressor 4.0/30 435 Psi Piston Air-Cooled Complete Parts

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

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.

Dryers, filters and air receivers can be supplied or specified together with the compressor so that pressure dew point and air quality match your blowing process. Please state your air quality requirements in the enquiry.

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.
