Inspection
Fans are thoroughly inspected and test run at the
factory prior to shipment. However, damage may
occur during handling and shipping. Consequently, it is
important that the unit be carefully inspected for visible
and concealed damage before beginning installation.
Report any damage to the shipper immediately. In
addition, assure all accessory items are accounted for.
Lifting Lugs

Upblast propeller fans are designed to discharge
contaminants up and away from the building for most
commercial jobs and many industrial applications.
These roof exhaust fans are produced with either
belt or direct drives and with steel or aluminum
blades. Drive frames and panels are constructed
to match the level of duty and motor size.
