]]> The primary application area of the PR-QP AT series fans is in civil and industrial air conditioning, ventilation, heating and filtration systems. These fans are designed for conveying clean or slightly dusty air at temperatures ranging from -20°C to +200°C in continuous operation.

The distinctive feature of the PR-QP AT series is its square/rectangular design, which allows four different orientations (0°, 90°, 180°, 270°) to be achieved with the same fan, while the elimination of the motor support frame ensures a compact installation footprint.

The series does not fall within the scope of the ErP 2009/125/EC Directive and subsequent regulations.

PRL fans can convey clean air, smoke or even slightly dusty air with temperatures between +100°C and +200°C  in standard configurations, and up to 300°C in special versions. The main characteristic of the PR-Q series is the rectangular construction, which allows the fan to be positioned in four different orientations (0°-90°-180°-270°) without any additional components. The lack of protruding motor support allows for a more compact design. Available in 6 sizes.

Airflow: up to 9 100 m3/h
Max static pressure buildup:  990 Pa
Max operating temperature: 100°C
