Designed for continuous operation

Extremely robust, durable and reliable the LEX 3 compressed air sander is suitable for all types of work in the workshop. Ideal for heavy duty applications in paintshops or the industrial sector because compressed air sanders are low maintenance and significantly lighter than electric power tools. A pad size of 77 mm and a sanding stroke of 2.5 mm makes the LEX 3 perfect for fine and final sanding. The sanding pad reduces flaws when first applying the tool to the surface of your workpiece, meaning less reworking and lower costs. Ensure a healthy working environment, pair your LEX 3 with a Festool dust extraction system and not only will you have low vibration levels and lower operating noises but also a dust free environment. Offering the lowest compressed air consumption of any air sander, the LEX 3 is guaranteed to reduce energy costs.

Main Applications

  • Finishing sanding
  • Sanding transitions when doing spot repairs/blending
  • Removing paintwork blemishes and paint drips
  • Sanding small surfaces, seams and edges
  • Trimming edges in furniture manufacture

Product Details

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.
