Technical Details for the LZB42 Series


Atlas Copco's LZB vane motors feature a five-vane design, delivering exceptional starting and low-speed performance. The motors boast a sleek and slender profile that effortlessly integrates into various applications with a range of optional mounting accesories.

Compact and lightweight, the lubrication-free air motors emit fewer lubricants into the air, making them suitable for sensitive processes and hygienic environments. However, for optimal performance and extended product life, both lubricated and lubrication-free variants benefit from a small quantity of oil from a lubricator.

Choose between standard and stainless-steel versions, depending on your model preference and with the integrated multi-step planetary gears, you can precisely tailor torque and speed to achieve optimal efficiency within a compact footprint and meet the unique demands of your application. If you are unsure, please feel free to contact us for assistance.
