To ensure reliable operation, stable performance and a long service life, it is recommended to follow the guidelines below during installation and commissioning.

• ✅ Use the fan exclusively for hot air circulation and distribution.
• ✅ Follow the airflow direction indicated on the fan.
• ✅ Install the unit in systems compatible with temperatures up to 150°C.
• ✅ Ensure adequate air circulation around the motor during operation.
• ✅ Carry out the electrical connection in accordance with local regulations and the manufacturer's instructions.
• ✅ Use ducting and accessories suitable for hot air applications.
• ❌ Do not install the fan inside combustion chambers.
• ❌ Do not use the unit to transport smoke, combustion gases or solid particles.
• ❌ Do not expose the fan to direct contact with flames, embers or radiant heat sources.

Additional Protection for Demanding Thermal Applications

The MMotors VO120H motor incorporates a winding impregnation system using high-quality insulating resins. This process helps reinforce the internal protection of the motor against moisture, dust, vibration and prolonged thermal stress.

The impregnation process contributes to improved electrical stability and supports reliable operation even in applications where the fan operates continuously with hot air.

• ✅ Protection against moisture and environmental contamination
• ✅ Improved winding electrical stability
• ✅ Additional resistance to mechanical vibration
• ✅ Enhanced reliability for continuous operation
• ✅ Designed for hot air applications up to 150°C

⚠️ CELSICLOCK® 99/177 INDICATOR

MMotors hot air fans incorporate a CelsiClock® 99/177 thermal indicator mounted on the motor.

This system allows a visual check of the maximum temperature reached during fan operation.

It provides a quick reference for verifying operating thermal conditions in hot air applications.

CelsiClock® is an informational thermal indicator and does not perform control, regulation or thermostat functions.

MMotors offers hot air fans rated up to 150°C in different diameters, configurations and versions with integrated thermostat control, helping you select the most suitable solution for every installation.
