Stops vibrations. Increases efficiency.

Stops vibrations, increases efficiency. With a 3 mm sanding stroke, the LEX 3 150/3 compressed air eccentric sander creates a high-quality sanding finish, e.g. with the final sanding of filler in the four-step sanding process or with the fine and final sanding of roundings and sanding of blending zones. Weighing just 1 kg, with minimal vibration values, comfortably low noise levels, a robust and durable motor as well as extremely low compressed air consumption, it is suitable for both automotive applications and kitchen and furniture assembly.

  • Precise – sanding pad brake ensures a clean pattern
  • Low compressed air consumption ensures high cost savings
  • Perfect dust extraction and economic abrasive consumption – thanks to the high-quality sanding pad with MULTI-JETSTREAM 2 principle
  • Low vibration levels and a pleasant operating noise protect the user's health
  • Extremely sturdy design ensures a long service life, minimal servicing requirements and high cost savings
  • Simplifies permanent dust extraction, guarantees the best working results and protects the user's health when combined with the IAS 3 light hose
  • High-quality FUSION-TEC sanding pad with MULTI-Jetstream principle ensures efficient dust extraction, minimises rework and saves on costs
  • Fine 3 mm sanding stroke produces a very high-quality sanding finish and saves on costs
  • Sanding pad brake reduces sanding errors when setting down the machine, thereby avoiding rework and additional costs
  • Note: an IAS 2/IAS 3 connecting system is required for operation

Product highlights

  • Achieve ideal results more quickly:

    Dust-free for first-class varnishing results: The IAS system guarantees perfect dust extraction and compressed air supply.

  • Convenient and safe:

    Lightweight, handy, low-vibration, quiet – for fast work and a healthy working environment.

  • Systems get it done:

    Perfectly matched: Tool, sanding pad and abrasive – for gleaming results and considerable time savings.

Product details

  • Extremely robust and durable

    The low-maintenance and robust motor with double-sealed bearings and high speed rigidity minimises downtimes and guarantees a long service life.

  • Three functions in one: The IAS system

    The IAS three-hose system combines three functions in a single hose: Compressed air supply, exhaust air extraction and dust extraction. Sanding dust and exhaust air are kept away from the work surface. Thanks to an intelligently designed exhaust air extraction system, no cold air escapes: Hands and wrists stay warm, work is more comfortable and better for health.

  • Designed to fit your hand

    Accurate guidance and precise sanding thanks to SoftGrip coating on the device. The well-balanced ergonomics also ensure effortless work.

  • Minimal compressed air consumption

    Less is more. The LEX 3 150 has the lowest compressed air consumption of them all: Just 290 l/min. That's approx. 30% less than devices from other manufacturers – which saves a lot of money.

  • Maximum surface quality

    The unique sanding pad brake prevents the sanding pad from turning upwards and prevents the surface being scratched during sanding, thereby minimising both reworking and costs.

  • Less reworking

    The high-quality FUSION-TEC sanding pad with MULTI-JETSTREAM technology has a low height and therefore a better feel for the surface. The risk of material damage and costly rework is reduced considerably.

  • Lower abrasive consumption, lower costs

    The patented MULTI-JETSTREAM sanding system is a unique system that operates with intake air and exhaust air to generate an air flow that actively transports the sanding dust to the nearest extraction channel. The result: Almost 100% dust extraction, a constant removal rate, excellent surface quality and a considerably longer service life of the fastener and abrasive.

  • Pad hardnesses for every application

    Hard, soft, ultra-soft. Festool offers sanding pads with three different degrees of hardness for work that is optimally adapted to the material and surface.

  • Speed adjustment during sanding

    The ergonomic position of the speed pre-selection enables infinite adjustment with the thumb, even during sanding.

  • Clearly visible stroke indicator

    The sanding stroke is printed on the head of the ergonomic dead-man switch as a clearly legible number. The dead-man switch is also used as a variable speed trigger for controlled sanding.

Main applications

  • Fine and final sanding, ideal for curves
  • Final sanding of filler, e.g. in 4-step sanding system
  • Light sanding of blending zones
  • Sanding high-gloss surfaces ready for polishing
  • Sanding wooden surfaces ready for waxing
  • Final sanding of clear coats, wood, plastic and mineral materials

Performance features

  • Vibration stop

    Patented VS balancing so that tools run smoothly during sanding, which makes working less hazardous.

  • StickFix STF

    Quick, economical fastening system for abrasives – no adhesives, no clamping.

  • Quick-acting brake

    For safe work when planing, sawing and routing.

  • IAS 3

    Hose system incorporates compressed air, dust extraction and exhaust air.
