Higher pressure with less pressure stages, that's how the new LW 300 E III Compact from L&W presents itself. Working pressure up to 420 bar, the new limit for our latest 3-stage L&W compressor.

Industry-proven components, in the usual L&W quality, combined with a very low rpm, guarantees long life times, low maintenance intervals and low maintenance costs.

The compressor can be individually equipped based to customer requirements.
