Atlas Copco PZB15-RL-AR500-20 | PZB15 Piston Air Motor — Reversible, Stainless Steel, IEC Flange
Purpose-built for demanding process and automation applications, the Atlas Copco PZB15-RL-AR500-20 is a stainless steel piston air motor delivering 0.12 kW (0.16 hp) with fully reversible operation, precision low-speed control, and 25–40% lower air consumption than vane alternatives. IEC Flange.
Performance at a Glance
This piston motor delivers 3.93 Nm at 297 RPM peak output (stall torque: 7.8 Nm). Centrifugal piston technology enables reliable high-torque starting at extremely low speeds — a performance envelope no vane motor can match below 100 RPM. Consumes 25–40% less compressed air than equivalent vane motors.

Key Features
- Max Output Power: 0.12 kW (0.16 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
- Stainless Steel Construction: Full stainless steel (316L-grade) body and motor cell resists corrosion in washdown, food-grade, and chemical environments. 100% silicon-free — safe for processes where silicone contamination is unacceptable.
- 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 — IEC Flange: 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
- Precise low-speed actuation in cleanroom and automation
- Chemical and pharmaceutical dosing equipment
- Drop-in replacement for electric gearmotors in ATEX zones
- Stop-start high-cycle actuation applications
- Hazardous area installations requiring ATEX Zone 1/21 certified pneumatic drives
- Environments where electric motors present ignition, EMI, or water ingress risks
The PZB piston motor's centrifugal piston design achieves high starting torque at extremely low speeds — a performance profile no vane motor can match below 100 RPM. The fully reversible pneumatic circuit enables bidirectional operation without external flow-switching valves, simplifying installation and reducing component count.
The stainless steel (RL-series) housing mates directly to standard IEC and NEMA motor flanges, making drop-in replacement of electric gearmotors straightforward — with all the inherent safety advantages of pneumatic drive in ATEX and explosion-risk zones. A built-in inductive sensor port (M5) enables easy closed-loop speed monitoring.
