Overview of the LW 300 E III Compact 420 Bar Compressor
The LW 300 E III Compacht 420 bar is the first 3-stage 420 bar high pressure compressor in our product range.
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.
