Compressed air sander: IAS 3 connecting system is required for operation
With a 5 mm sanding stroke, the LEX 3 150/5 compressed air eccentric sander ensures fast working progress and a high-quality sanding finish, e.g. with the coarse and intermediate sanding of flat surfaces and roundings or repair compounds in the four-step sanding process. 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 – for the intermediate sanding of wood, paint and varnish and preliminary sanding of solid surface materials.
Achieve ideal results quicker
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 clean working environment.
Systems get it done
Perfectly matched: Tool, sanding pad, and abrasive – for gleaming results and considerable time savings.
Extremely robust and durable
The low-maintenance and robust motor with double-sealed bearings and high-speed rigidity minimizes downtime.
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.
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 3 150 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 minimizing 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 hardness 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.
