CAF • Axial fans

Cased axial duct fan
Until 73.000 m3/h
Short, middle or long case
IP55

Datasheet

Cased axial fans used for large air capacities with relatively low pressures are required in duct mounted applications.

Application

Suitable when large air capacities with relatively low pressures are required in duct mounted applications. For instance: ventilation and conditioning in naval and mining applications, evaporative towers, heat exchangers, cooling of electric and refrigerating equipments, etc.
With this line is possible to attain higher pressures using the multistage version consisting of two single stages fans mounted in series, with contra-rotating impellers. This solution allows the recovery of the air rotative component turning it in pressure, developing up to 2.7 times the pressure of a single fan having the same geometry and speed.

Composition

Casing in steel sheet protected with epoxy painting. Fixing flanges according to UNI-ISO 6580/EUROVENT 1-2 standards.
Impeller with high efficiency airfoil blades in plastic material or in die-cast aluminum alloy. Hub in die-cast aluminum alloy. Balancing according to UNI ISO 1940. Variable pitch angle in still position.
Asynchronous electric motor, protection IP 55, class F insulated, output EFF2, service S1, form B3, construction according to the IEC/EEC (UNEL-MEC) standard.
Execution 4 (impeller directly coupled to motor shaft).

Options

Performances differing from standard
