Festool Compressed air eccentric sander LEX 3 77/2,5 Description

Nothing produces a finer finish: With a pad diameter of just 77 mm and weighing just 700 g, the LEX 3 77/2.5 compressed air eccentric sander is the perfect professional tool for sanding small areas, e.g. at transitions during spot repair and blending. Or for sanding difficult to access areas, beading and edges. At the same time, the LEX 3 77/2.5 is robust, durable and, thanks to minimal compressed air consumption, guarantees high cost savings – with both low vibration values and low noise.

Strengths and benefits

  • Sanding pad brake reduces sanding errors when setting down the machine, thereby avoiding rework and additional costs
  • Low compressed air consumption ensures high cost savings

Main areas of use

  • Finishing
  • Sanding transitions when performing spot repairs/blending small surfaces
  • Removing paintwork blemishes and paint drips (polishing preparation)
  • Sanding inaccessible surfaces, small surfaces, seams and edges
  • Trimming edges and sanding small surfaces in furniture manufacture

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.

Built for manual operation

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 77/2.5 has the lowest compressed air consumption of them all: Just 270 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.

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.

Notes

  • Note: an IAS 2/IAS 3 connecting system is required for operation
