Atlas Copco LZB22-L-LR100-11 | LZB22 Vane Air Motor — Ultra-High Speed, Low-Speed Reversible, Lube-Free

The Atlas Copco LZB22-L-LR100-11 is a lubrication-free LZB22 gear-reduced vane air motor with a 110 RPM free speed and an output shaft rated to 9 Nm (6.6 ft-lb). Fully reversible, standard keyed shaft, 0.95 kg (2.09 lb).

Performance at a Glance

This gear-reduced build has a free speed of 110 RPM, with the output shaft rated to a maximum permitted torque of 9 Nm (6.6 ft-lb). Atlas Copco does not publish output power or torque-curve data for this gear-reduced build, so we have left those figures off rather than estimate them. Contact us for application sizing. Suited to slow-turning agitators, rotary indexing and geared valve actuation.

Technical Specifications

Key Features

• Rotation: Fully Reversible—switchable by reversing air connections, no disassembly required
• Lubrication-Free Vane Design: Lubrication-free vane material eliminates in-line air oilers and prevents lubricant contamination of your process or product — ideal for food, pharma, and clean manufacturing environments.
• ATEX Certified — Ex II 2 G Ex h IIC T6 Gb (gas) and Ex II 2 D Ex h IIIC T85°C Db (dust), to EU Directive 2014/34/EU, for ambient temperatures up to +40°C (104°F). Safe for use in classified areas where electric motors are prohibited.
• Output Shaft — Standard Keyed Shaft: Direct integration into existing drive trains, couplings, sprockets, and IEC/NEMA machine interfaces
• Overload Safe: Stalls harmlessly under overload; self-starts when load is removed — no thermal protection, burnout risk, or electronic fault recovery needed
• Infinitely Variable Speed: Regulate output speed and torque via inlet pressure or flow control valve — no electronic drives or VFDs required
• Atlas Copco Quality: Designed and manufactured to ISO 9001 standards; global spare parts and service network with application engineering support

Ideal Applications

• Slow-turning agitators and paddle mixers
• Rotary table and turntable indexing
• Geared valve and damper actuation
• Hazardous area installations requiring ATEX certified pneumatic drives
• Environments where electric motors present ignition, EMI, or water ingress risks

The LZB22 uses Atlas Copco's zero-clearance vane motor design, here in a gear-reduced build, in a compact hardened steel and aluminium housing, giving a slim profile that drops into tight machine layouts without a redesign. Speed is infinitely variable by adjusting inlet pressure or flow, without mechanical governors or electronic drives.

External parts are hardened steel and aluminium. Inlet and outlet hose size 0.3 in.
