Discover the new LW 450 E III Compact, robust, dynamic, powerful.

The LW 450 E III Compact is ideal for dive centers, ships and boats with limited space. The Compressor impresses with very low maintenance intervals and service costs. A new, industry-proven lubrication system and reinforced components form the core of the advanced LW 450 compressor block and improves the lifetime of the compressor unit. The optional availible innovative condensate system with the new Condensate Stop Valve optimizes the efficiency of the compressor and includes a 10 litre collection tank as well as a highly effective 0.8 litre pre-separator for prolonging filter lifetime.
