Air Motor LZB33 0.23-0.39 kW

Name: Air Motor LZB33 0.23-0.39 kW
Brand: Atlas Copco

LZB33 series, versatile air motors with high torque and braking options.

Air Motor LZB33 0.23-0.39 kW

Air Motor LZB33 delivers a unique combination of versatility and power, featuring a wide range of models including High-Torque, Low-Speed, and Brake-Module versions. This series is engineered to drive complex industrial applications requiring absolute reliability and oil-free operation.

The LZB33 uses dry vane technology for oil-free operation in clean environments. Atlas Copco’s planetary gearing enables high torque in a compact format, with High Torque models producing up to 260 Nm. The motor withstands overloads and can be stalled under full load without mechanical damage or overheating. Brake (LB) versions use a spring-applied, air-released brake for lifting and indexing applications. All models are fully ATEX certified for explosive atmospheres. Model-selection guidance is available through the Air Motor Selection Tool and the full Air Motors catalog.

Key Features of Air Motor LZB33

Extensive Configuration Options: Available in Standard, Low Speed (LR), High Torque, and Brake (LB) versions to perfectly match your application.
Power in a Compact Package: Delivers power output up to 0.39 kW and maximum torque up to 260 Nm (in High Torque models), while maintaining low weight.
Clean and Green Operation: Lubrication Free technology ensures an oil-free work environment and reduces air line maintenance.
Uncompromised Safety: Explosion-proof design with ATEX certification (Ex II 2GD) standard on all models.

Frequently Asked Questions

Q: What applications is the Air Motor LZB33 best for?
A: The series excels in applications requiring high power at low speeds, such as heavy conveyors, viscous mixers, hoists (LB models), and automatic dosing systems.

Q: What are the performance specs?
A: The LZB33 series covers a power range of 0.23-0.39 kW. The High Torque models provide immense starting torque, while high-speed models reach up to 9,400 r/min, all meeting strict industrial precision standards.
