Description

PR-Q HT is a series of backward curved centrifugal fans suitable for high temperature smoke extraction.

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 tank to the absence of the motor support.
The series is suitable for running at the temperature of 100°C in S1 service and CE certified to F400 by the independent notified body Applus according to EN 12101-3.
