产品介绍
The DJZ-2/30(40) – DJZ-8/30(40) series is a family of compact oil-injected booster compressors engineered specifically for PET bottle blowing lines. Built on the proven DJZ platform, these units take existing shop air at 0.8–1.0 MPa and boost it to a stable 3.0–4.0 MPa, delivering 2–8 m³/min of high-pressure air for stretch-blow moulding, preform handling and utility supply. Air-cooled and floor-mounted, every model ships factory-aligned and ready to pipe in.
The DJZ-4/30(40) delivers 4 m³/min at 3.0-4.0 MPa, combining dependable multi-stage compression with automatic protection and low operating cost. Dejue (BS986) manufactures this unit in-house to CE and ISO standards, with full documentation, spare-parts support and export packing as standard.

Key Features
- Oil-injected lubrication for long service life and reliable sealing in multi-stage compression
- Boosts shop air from 0.8–1.0 MPa to 3.0–4.0 MPa without a separate high-pressure plant
- Four models covering 2, 4, 6 and 8 m³/min to match line speeds from small blowing heads to full-scale plants
- Compact air-cooled frame on a vibration-isolated base — installs beside the blower
- Automatic start/stop pressure control with safety valve, pressure gauge and drain system
- Low-noise, low-maintenance design with long-life bearings and service-friendly access panels
Typical Applications
- PET bottle blowing machines for water, CSD, juice, edible oil and dairy packaging
- Stretch blow moulding (SBM) and injection-blow moulding (IBM) lines
- Preform handling and mold clamping air supply
- Pneumatic testing, leak testing and pressure vessel charging
- General plant high-pressure air where 8–10 bar supply is insufficient
