The L91 adjustable belt grinder in the three-phase configuration with base and dust extraction is intended for users who need a complete workstation for controlled stock removal, finishing and process cleanliness. The dedicated base provides stable support and balanced load distribution, while the integrated extraction system improves management of abrasive dust and residue generated during deburring, satin finishing, blending and surface preparation. This combination is especially suitable in departments where continuous operation, workplace cleanliness and operator protection are important parts of the production workflow. The 400 V three-phase motor with 2/3 HP power and speeds of 1400/2800 rpm allows the machine to run the belt at 15 or 30 m/s, adapting its behaviour to different materials and finish requirements. The 50 mm belt with 2000/2500 mm length supports productive repetitive work, while the Ø200 x 50 mm contact wheel keeps the working point stable and helps achieve consistent surfaces. The 72 dB noise level, together with ASP.1 extraction, makes this version well suited to industrial settings where dust dispersion must be controlled without sacrificing grinding capacity. With dimensions of 60x90x105 cm and machine weight of 85 kg, the L91 with extraction fits machine shops, fabrication departments, automotive environments and advanced industrial maintenance. It is the right choice for users seeking a grinder ready for intensive duty with improved workplace cleanliness and more orderly finishing operations.
