产品介绍
DJW320A Breathing Air Compressor is a high‑pressure air supply unit specially designed for applications such as diving breathing and firefighting breathing. The model adopts a four‑stage compression, three‑cylinder piston structure, which compresses ambient air step by step to high pressure. Equipped with an efficient filtration and purification system, it effectively removes moisture, oil, and impurities from the compressed air, delivering pure, dry, and safe breathing air that fully meets the standards for human respiratory use. The product features moderate size, compact structure, and stable operation, making it suitable for a variety of scenarios including diving clubs, fire brigades, underwater engineering, and air tightness testing.

Top 5 Advantages – DJW320A Breathing Air Compressor
1. Efficient 4‑stage compression for stable high‑pressure output
With 3 cylinders and 4 progressive stages, it delivers up to 330 bar at a consistent flow of 320 L/min, ideal for demanding diving and firefighting filling tasks.
2. Triple safety valves + auto‑stop for complete protection
Independent safety valves on each stage (3 total), plus automatic shutdown at preset pressure, eliminate over‑pressure risks and allow unattended operation.
3. Dual filling outlets double your productivity
Equipped with 2 G5/8 filling hoses, it can charge two cylinders simultaneously, drastically reducing waiting time – perfect for batch filling.
4. Forced oil pump lubrication for extended durability
The built‑in forced lubrication system ensures all key moving parts are well‑oiled, minimising wear and extending service intervals and overall lifespan.
5. Air‑cooled design offers flexible, plug‑and‑play installation
No external water supply required. With a footprint of only 0.83 m² and a weight of 138 kg, it is easy to move and suits various indoor and outdoor job sites.
