When is an electric drive the better choice?

Electric drives offer particular advantages when the focus is on performance and control:

  • High speeds & torques: Ideal for large containers, viscous media or processes with a high shear profile.
  • Precise control: Optionally with precise speed control.
  • Data collection: Reading out data such as speed, torque, motor current, power and temperature is straightforward.
  • Specialist knowledge: Knowledge about the handling of electrical systems is already available in most companies.
  • Existing equipment: In laboratories, for example, there is often only an electrical infrastructure for connection.

Typical application scenarios:

  • Large-volume mixing containers
  • Highly viscous media
  • Processes with high shear rates
  • Stirring systems with long running times

When is a pneumatic actuator the better choice?

Pneumatic drives are particularly impressive in environments with special requirements:

  • Moisture & cleaning: PTM air motors are insensitive to moisture and frequent cleaning cycles.
  • ATEX zones: The use of air motors in ATEX zones is considerably cheaper than the electric alternative.
  • Hygienic processes: The simple, hygienic design of the PTM air motor is particularly advantageous in the pharmaceutical, food and cosmetics industries.
  • Simple integration: Air motors do not require a power supply and can be easily integrated into existing compressed air systems.

Typical application scenarios:

  • Areas sensitive to cleaning
  • Clean and ultra-clean rooms
  • Ex zones
  • Small to medium-sized containers
  • Media with medium viscosity

Did you know,
that air motors can also be quiet and efficient?

Our air motors have the same noise level as electric motors. This allows us to create a pleasant working environment with both types of drive.

Our air motors are also extremely efficient. Every ounce of energy used is converted into powerful movement and therefore delivers an excellent economic balance. You can find even more information on our „Efficiently moved“ page:

Conclusion: Your requirements decide

There is no one-size-fits-all answer - but there are clear decision criteria.
Anyone working in hygiene-critical or potentially explosive areas relies on pneumatics.
If you need a lot of power and control with viscous media or large volumes, an electric drive is the best choice.

What to do now:

Estimate your requirement:
- Environment (ATEX? humid? hygienic?)
- Viscosity of the medium
- Stirring process (shear forces?)
- Duration & frequency of operation
