The fans of the PR-Q series find their main application  in commercial and industrial plants of air-conditioning, ventilation, heating and filtering; They are designed for conveying clean or slightly dusty air, in a temperature range from 100°C to 200°C in continuous.

The main characteristic of the PR-Q series is the quadrangular construction, which allows to obtain four orientations (0°-90°-180°-270°) with the same fan. The dimensions are reduced thanks to the absence of the motor support.
