QSL

Mixed Flow Fan

Application

The QSL Mixed Flow Fan combines the benefits of axial flow and centrifugal flow fans. The QSL has the advantage of a compact design and straight-through airflow, as well as preferred acoustic characteristics and high pressure capability.

Mixed flow fans are a popular choice on many air supply, return and exhaust air applications in the HVAC industry for both constant and variable air volume systems. The efficiency and sound characteristics of the mixed flow fans are often desired in buildings such as hospitals, libraries, theaters and general offices. The heavy-duty construction of QSL fans also make them suitable for many industrial applications handling ambient air.
