Maintenance free

The clean exhaust air eliminates the need for time consuming rework. An oil free motor also results in significantly less servicing requirements and costs.

Cost effective

With the lowest compressed air consumption of any sander of its kind (only 270 litres per minute), the LEX 3 generation sanders can reduce energy costs by as much as 30%.

A pleasure to work with

Combine low noise emissions, low vibrations and low weight with an ergonomically designed shell and you are rewarded with a highly efficient sander that is comfortable to use over long periods of time.

Dust free

Use with a number of different extractors, including hazardous rated extractors for aluminium and carbon materials. One hose incorporates three functions - compressed air, exhaust and dust extraction.
