Dynair PR-Q HT Backward curved centrifugal fans F400

Backward curved blade centrifugal fans, suited for high temperature smoke extraction. 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. These PR-Q HT fans are suitable for continuous service up to +100°C and 2 hours at temperatures up to +400°C. This series of fans are F400 certified by the independent APPLUS committee, according to EN12101-3 standards.
