CFD/CFDS is a ducted junction box fan, with a forward-facing centrifugal blade that helps the fan
achieve high efficiency, large flow and pressure. Compact, inline-axle motor. With a box-shaped design,
the fan operates extremely smoothly, suitable for places with large areas and low noise requirements
such as schools, hospitals, buildings, offices, hotels…
Fan Type CFD: Standard type
CFDS: Super low noise type

Construction Information:

CFD/CFDS consist of box casing, impeller, motor, inlet and outlet flangesntrol.

Casing:

The fan is made from hot-dip galvanized steel sheet. The book has sturdy aluminum frames combined
with steel plates, making the fan sturdy. With model design and 2 door opening directions, it is
convenient for the construction process and maintenance. The Model S housing is equipped with
additional sound insulation, which reduces the fan’s 10Db compared to standard fans

Impeller:

Impeller is made of galvanized steel, the blades are folded together in a forward curved direction to help the
blades operate stably in harsh working environments, with a special design to help the fan achieve high
efficiency, flow rate Large, high efficiency. volume, big head and super low noise
All propellers are statically and dynamically balanced according to ISO 1940 with G2.5mm/s quality
standard.

The CFFD series uses a silent inline fan with high quality materials and a special ultra-low noise design with
a 3-layer dust filter system. The ultimate solution for high-end ventilation needs in commercial and
residential systems. Suitable for bedrooms, offices, living rooms, shops, hotels with low noise requirements
and providing high air quality, clean bacteria and safe for health.
