At 1,750 RPM (vs. 3,500 RPM for the smaller WEDA models), the L70N extracts more head per stage at lower wear, and runs cooler over multi-shift duty cycles.\u003c\/p\u003e\n\n\u003ch2\u003eService Footprint\u003c\/h2\u003e\n\n\u003cp\u003eAtlas Copco supports the WEDA L-series with a global parts inventory, rebuild kits matched to typical wear, and dealer-based field-service for major overhauls.
