AC Retangular 700mm CE/UL box/in-line/duct fan for quiet ventilation
A ducted fan is a propulsion arrangement whereby a fan, which is a type of propeller, is mounted within a cylindrical shroud or duct. The duct reduces losses in thrust from the tip vortices of the fan, and varying the cross-section of the duct allows the designer to advantageously affect the velocity and pressure of the airflow according to Bernoulli's Principle. Ducted fan propulsion is used in aircraft, airboats, hovercraft and fan packs.
1. Small volume
All of our fans are equipped with the unique external rotor motor, which makes the volume of fans smaller and easier to install and maintain a narrow area.
2. Novel design
The unique professional design of its appearance ensures that it is not necessary to add accessories to install. It is suitable for the size of the blast pipe saving more installation cost and time.
3. Application
Forward curved or backward curved centrifugal impeller adoption is up to its model. It is broadly applied in large-scare ventilation system of laboratory and library. Now the company has developed kinds of fans which design for exhaust, filtration, blow, circle and renew.
