Agitator / Compressed-Air Motors
Discover vane compressed-air motors with or without gearbox for pressure and mixing tanks – variable speed, with high starting torque, optionally in stainless steel, oil-free or ATEX-certified. From viscosity and impeller type to torque, speed and air consumption through to the interface (flange, coupling, shaft), we configure your motor precisely to the medium and process.
Use cases & benefits
Process-safe starting torque even with tough viscosities, finely adjustable speed for homogenizing, mixing and dispersing, plus robust hazardous-area operation with ATEX variants. Properly sized air motors shorten setup and cleaning times, reduce energy and maintenance costs and raise repeatability – in workshops and series production.
Technology & settings
- Torque & speed: matched to viscosity, impeller type and batch height; use gearboxes (planetary or worm) for low speeds and high torque.
- Air consumption: size to load point and operating pressure; include a service unit (filter, regulator, lubricator) and silencer.
- Material: steel or stainless steel, optionally oil-free for sensitive applications.
- Safety: observe ATEX and grounding requirements in hazardous zones.
- Interface: choose flange, coupling or shaft to suit agitator geometry and tank type.
Accessories & integration
Accessories include gear units, speed controllers, service units (FRL), silencers, shafts and couplings, flange and adapter plates, ATEX grounding, torque arms and sensors for speed, temperature and operating states. We perform the compatibility check (tank, medium, ATEX zone, interface) and integrate the motors optimally into pressure tanks and systems.
Key benefits at a glance
- High starting torque for viscous media
- Finely adjustable via throttle/regulator or VFD drive package
- ATEX & stainless for sensitive/hazardous applications
- Compatible with common agitator systems

Learn moreFrequently asked questions about agitator / air motors
What types of agitator air motors are there and what are they suited for?
Common are vane air motors with high starting torque, either direct drive or via gearboxes (planetary/worm) for high torque at low speed. Stainless and oil-free variants suit sensitive media; ATEX motors are for hazardous areas. They reliably drive propeller, dissolver, anchor and folding agitators.
How do I size torque, speed and air consumption?
Starting from viscosity, impeller geometry and desired tip speed, determine the required torque with a safety factor. The speed follows from the mixing task and tank geometry; gearboxes reduce speed and increase torque. Air consumption depends on the load point and operating pressure— plan line cross-section, service unit and silencer.
Which factors influence lifetime, noise and explosion protection?
Clean, dry compressed air, correct lubrication (or oil-free design), suitable filters/regulators/lubricators and a moderate duty cycle increase lifetime. Silencers, enclosure and lower speed reduce noise emissions. For hazardous areas, observe ATEX zones, grounding, conductive components and low-spark materials.
