Dynair PR-Q AT Backward curved blade centrifugal fans for clean air or slightly dusty air with t from 100 to 200°C

The PR-Q series of fans are designed  for industrial or commercial applications, for heating, ventilation, air-conditioning, or filtering in large estabilishments. 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.

Max static pressure buildup:  990 Pa
Max operating temperature: 100°C
