Serie ADNAX D - Kanalvetilator mit Asynchtomotor

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 impeller, with forward curved blades is made of galvanized steel and powered by a 4, 6 or 8-pole external rotor asynchronous motor. Such a modification ensures high air flow capacity and relatively significant differential pressure. For thermal overheating protection, thermal contacts with terminals leading outside, are incorporated in the motor winding for connection with external protection devices. 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 designed for inline rectangular air duct mounting 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. The fans can be mounted in any position with respect to the pointer direction on the casing. Access for fan maintenance should be provided. The fan is powered through its external terminals. The casing is provided with a removable access door for maintenance.
