Atlas Copco LZB14-L-A029-12 | LZB14 Vane Air Motor — Medium Speed, Clockwise, Lube-Free

The Atlas Copco LZB14-L-A029-12 is a lubrication-free LZB14 vane air motor with a free speed of 2,900 RPM, delivering 0.16 kW (0.21 hp) and 1.15 Nm (0.85 ft-lb) at its 1,330 RPM max-output point. Clockwise rotation, threaded shaft, 0.30 kg (0.66 lb).

Performance at a Glance

This speed code tops out at 2,900 RPM free and does its useful work around 1,330 RPM, where it makes 0.16 kW (0.21 hp). Minimum starting torque is 2 Nm (1.48 ft-lb) and stall torque is 2.3 Nm (1.7 ft-lb), so it starts under load and stalls harmlessly rather than tripping. Suited to pump and agitator drives, conveyor drives and packaging machinery.

Technical Specifications

Key Features

• Max Output Power: 0.16 kW (0.21 hp) at 1,330 RPM — rated for continuous-duty operation in fixed-plant and automation environments
• Rotation: Clockwise—factory-set for consistent directional performance
• 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 — Threaded 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
• IP66 Rated: Sealed against dust ingress and powerful water jets for washdown and outdoor installations
• Atlas Copco Quality: Designed and manufactured to ISO 9001 standards; global spare parts and service network with application engineering support

Ideal Applications

• Diaphragm and gear pump drives
• Agitator and paddle stirrer drives
• Roller and belt conveyor drives
• Packaging and filling machinery drives
• Hazardous area installations requiring ATEX certified pneumatic drives
• Environments where electric motors present ignition, EMI, or water ingress risks

The LZB14 is the smallest frame in Atlas Copco's vane motor range, built on the same zero-clearance vane design 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, and the linear torque-speed curve makes control predictable and repeatable across the working range.

Air consumption at maximum output is 4 l/s (8.5 cfm). External parts are hardened steel and aluminium. Inlet and outlet hose size 0.3 in.
