Power Transmission
for Ventilation
Your Fan Must Maintain Consistent Airflow Without Constant Supervision
Ventilation fans are often required to deliver a constant airflow rate over extended operating periods without direct monitoring. Every belt in the drive system must maintain stable tension throughout its service life, as tension loss can gradually reduce airflow performance. In addition, noise generated by the drive system itself adds to the airborne noise already present within the ventilation network, directly affecting occupant comfort.

Ribbed Belts for Ventilation Fans
Ribbed belts transmit torque through multiple longitudinal ribs rather than a single large belt section.
This design enables the use of smaller pulley diameters while reducing operating noise, helping minimize the additional sound generated by the drive system within the ventilation network. As the originator of this technology, we remain globally recognized for our expertise in computational drive selection and optimization for ribbed belt applications.
Elastic Belts
Elastic belts require no tensioning device, as their inherent elasticity provides automatic and continuous tension throughout the drive system.
This eliminates the need for periodic re-tensioning, making them ideally suited to fans operating without continuous supervision. This reliability is particularly valuable in ventilation systems, where a gradual reduction in airflow may go unnoticed until occupant comfort is affected.
