General Introduction:The round duct fan consists of casing, propeller, motor and wiring
box. The overall dimensions of air let and air outlet are the same,
the fan can be connected with air duct directly, so pipeline design
and installation costs can be greatly saved. The newly designed
casing and the paddle-wheel designed according to aerodynamics can
greatly reduce vibration and noise level. GDF series round duct fan
is suitable for the hotel, supermarket, warehouse, bathroom, etc.
to supply and exhaust air
Product Advantages:1.The casing is made of cold-rolled sheet or galvanized sheet which
prevents rusting;2.The inlet and outlet sizes are the same, easy for installation and
can save installation cost;3.The impeller is installed directly on the motor shell, which is
steadily driven by the motor with high efficiency;4.The wiring box is installed outside the fan which is easy to
install and maintain.
Maintenance Suggestions:1. When doing maintenance, make sure that electrical service to fan
is locked in the “OFF” position to prevent from being switched on
accidentally. When the service disconnecting means cannot be
locked, securely fasten a prominent warning device such as a tag to
service panel.2. Do not start power supply until maintenance or service work has
been completed.3. Maintenance or service work must be performed by a qualified
person in accordance with all applicable codes and standards,
including local fire codes.4. Impellers must be inspected regularly. In order to inspect
impeller, remove fan from the duct work, and remove any
obstructions and clean with damp cloth.
