Series ADNAX

APPLICATION

Inline rectangular fans are intended for supply and exhaust ventilation of residential, public and industrial premises (production and storage facilities, sport halls, swimming pools, large auditoriums, conference halls, etc.). The fans are designed for mounting into rectangular ducts. The fans are rated for continuous operation, always connected to mains power.

DESIGN

Fan casing is made of galvanized steel.

MOTOR

The impellers with backward curved impeller blades are made of galvanized steel and are powered by means of a 2 or 4-pole asynchronous motor with an external rotor. Motors are supplied with incorporated overheating protection  and with automatic restart or thermal protection terminals leading outside for connection to external protection devices depending on the model, as per the wiring diagram. The motor is equipped with ball bearings for a long service life. For precise features, safe operation and low noise, each impeller is dynamically balanced during assembly. Motor protection rating IP 44.

SPEED CONTROLLER

Both smooth or step speed control is performed by means of a thyristor or autotransformer controller. Several fans may be connected to one speed controller provided that the total power and operating current do not exceed the rated speed controller parameters.

MOUNTING

The fans are mounted into the rectangular ducts and require no special fixing in case of direct connection. In case of connection through the flexible connectors, the fan is fixed to a building by means of supports, suspension brackets or fixation brackets. Fans can be mounted in any position with respect to the airflow direction (indicated with an arrow on the casing). Access for fan maintenance should be provided. The fan is powered through its external terminals. The casing is equipped with a removable access cover for maintenance purposes.
