The QUBe SQU-HT is a multi-discharge, double skinned fan unit incorporating the high performance backward curved Ziehl-Abegg RH-C impeller designed specifically for operation without a scroll. With motor out of the airstream it is suitable for more arduous and elevated temperature applications. The unit is supplied as either an end inlet vertical discharge unit (QUBe-HT) or as a side inlet vertical discharge unit (QUBe-HTs)*.
*Please specify at the time of ordering.
