• ✅ Ensure adequate airflow around the motor during operation.
• ✅ Perform electrical connections according to local regulations and manufacturer instructions.
• ✅ Use ducting and accessories suitable for hot air applications.
• ❌ Do not install the fan inside combustion chambers.
• ❌ Do not use the fan 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 VO150H motor incorporates a winding impregnation process using high-quality insulating resins. This technology helps strengthen the motor’s internal protection 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 directly on the motor.

This system allows visual verification of the maximum temperature reached during operation.

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

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