Product highlights
- 7 mm sanding stroke Designed for fast material removal and quick coarse sanding progress.
- 150 mm sanding pad Covers larger surfaces efficiently while maintaining good control.
- Low compressed air consumption Uses only 310 l/min at rated load for efficient pneumatic sanding.
- Low vibration design Helps reduce operator fatigue during longer sanding sessions.
- Quiet operation Comfortable workshop use with controlled sound levels.
- Robust pneumatic motor Low-maintenance design with double-sealed bearings for long service life.
- MULTI-JETSTREAM 2 sanding pad Supports efficient dust extraction and consistent sanding performance.
- Sanding pad brake Helps reduce sanding errors and surface scratches when placing the machine onto the workpiece.
- IAS system compatibility Combines compressed air supply, dust extraction and exhaust air handling in one efficient hose system.
Extra Information
- The LEX 3 150/7 requires an IAS 2 or IAS 3 connecting system for operation.
- The 7 mm stroke is best suited to coarse sanding and fast material removal.
- For intermediate sanding, the LEX 3 150/5 may be a better fit, while finer sanding applications may suit a smaller stroke model.
- The IAS hose system combines compressed air, dust extraction and exhaust air management for cleaner and more comfortable sanding.
- Use with suitable Festool abrasives and sanding pad hardness for the surface and sanding stage.
Pro Tips
- Use the LEX 3 150/7 for the first coarse sanding stage, then step down to a finer stroke or finer abrasive for finishing.
- Choose a hard sanding pad for flat surfaces and a softer pad when working on shaped or more sensitive surfaces.
- Pair the machine with the Festool IAS hose system for the best compressed air supply, dust extraction and exhaust air handling.
- Do not press too hard while sanding; the 7 mm stroke is already designed for fast removal.
- Use a controlled grit sequence to reduce scratch marks before paint, varnish or clear coat finishing.
How to Use
- Fit the correct 150 mm StickFix abrasive disc to the sanding pad.
- Connect the required IAS 2 or IAS 3 hose system to the sander.
- Make sure the compressed air supply is clean, dry and set to the correct operating pressure.
- Connect suitable dust extraction before starting work.
- Place the sanding pad flat on the workpiece before starting the sander.
- Start the sander and guide it evenly across the surface using light, controlled pressure.
- Work through the required abrasive grits according to the sanding stage and final finish required.
- Allow the sanding pad to stop before lifting the machine from the surface.
- After use, disconnect the air supply and clean dust from the machine and sanding pad area.
