MMotors High Temperature Fans up to 150°C

High Temperature Fans for Fireplaces, Heat Recovery and Ventilation

MMotors high temperature fans are designed to operate safely and continuously in applications where conventional fans cannot withstand the presence of hot air. Built with components specifically selected for elevated temperatures, they provide a reliable solution for hot air circulation, distribution and extraction in residential, commercial and industrial installations.

Each MMotors hot air fan has been developed to ensure stable and continuous airflow even in systems exposed to high temperatures for extended periods. Their robust construction makes them ideal for heating systems, heat recovery units, fireplaces and industrial applications where reliability is essential.

MMotors hot air extractor fans are widely used in warm air heating systems, heat recovery installations, fireplaces, industrial ovens and technical ventilation projects where thermal resistance, durability and continuous operation are required.

The MMotors range includes axial fans for round ducts, square axial fans for equipment integration and dedicated models for saunas and steam rooms. Depending on the model, continuous operation is possible at temperatures up to 140°C or 150°C.

Why choose an MMotors hot air fan?

Standard ventilation fans are not designed for prolonged operation with hot air. MMotors high temperature fans use specially selected motors, materials and bearings engineered to withstand demanding thermal conditions while providing stable airflow and long service life.

• Excellent heat resistance.
• Continuous-duty operation.
• Low maintenance requirements.
• Designed for professional applications.
• Available in axial, tubular and square configurations.

Typical applications

MMotors high temperature fans are widely used in installations where hot air must be moved continuously and reliably:

• Wood-burning fireplaces and inserts
• Pellet and biomass stoves
