BREATHING AIR / COMPRESSED AIR COMPRESSORS
LW 450 E III 
LW 450 ES III Water separators after each stage
L&W delivers high-pressure compressors and the complementary modules for purification, storage and filling.
Stationary high pressure compressors for industrial compression of air – purification with breathing air quality.
The sturdy design of our compressors provides a maximum operating safety. Take profit of our know-how in a wide range of applications, e.g. high pressure test systems, pressure chambers, high pressure storage for pneumatic tools and many others.
Our compressors are designed for your individual application with a high degree of expandability according to your requirements.
Applications
| Type | From | To |
|---|---|---|
| Inlet pressure | atmospheric | 150 bar (2100 psi) |
| Delivery capacity | 6 m³/h (3,5 cfm) | 700 m³/h (420 cfm) |
| Final pressure | 10 bar (140 psi) | 420 bar (6100 psi) |
We individually calculate compressor and drive power according to your application requirement. In this way, we perform the best possible efficiency and highest economic feasibility for you.
