Atlas Copco LZL25-BF322-A-018 | LZL25 Vane Motor + 2-Stage Helical Gearbox — 18.2:1 Ratio, Type-A-Type
Where compressed air meets precision engineering, the Atlas Copco LZL25-BF322-A-018 pairs the LZL25 six-vane motor with a 2-Stage Helical Gearbox at 18.2:1 ratio, delivering up to 5.0 kW (6.7 hp) of high-torque low-speed output in one compact, fully reversible drive unit.
Performance at a Glance
The integrated 2-Stage Helical Gearbox delivers a 18.2:1 reduction ratio, converting the motor's high-speed vane output into controlled low-speed, high-torque shaft power. At this ratio, the unit targets viscous mixing, stirring, valve actuation, and tension control. Helical gear stages deliver high mechanical efficiency with smooth, low-noise power transmission.

Key Features
- Max Output Power: 5.0 kW (6.7 hp) at 6.3 bar (91 psi) — rated for continuous-duty operation in fixed-plant and automation environments
- 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 Zone 1/21 Certified — Approved for hazardous gas and dust atmospheres up to +40°C (104°F) in fixture-mounted use (EU Directive 2014/34/EU). 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
- Heavy-duty mixing requiring extreme output torque
- Torque-intensive gear-driven machinery
- Long-run low-speed process drives
- Slow-speed conveyor and indexing drives
- Hazardous area installations requiring ATEX Zone 1/21 certified pneumatic drives
- Environments where electric motors present ignition, EMI, or water ingress risks
The LZL25 vane motor connects to the 2-Stage Helical Gearbox via a standard IEC interface, enabling field-swappable motor replacement without disturbing gear unit alignment. The helical gear stages deliver high efficiency and smooth, quiet power delivery — no efficiency losses from chain or belt reduction. Both the motor and gearbox are lubrication-free in their vane cell and sealed for long service intervals.
Speed can be regulated down to 10% of free speed, and torque down to 20% — giving process engineers precise control over mixing intensity, conveyor rate, or positioning force from the air supply alone, without complex electronic speed drives.
