    Sound-Insulated Box Fans

    Series- DSIF

    Applications

    DSIF fan design enables its application in supply and exhaust ventilation systems for the premises with high requirements to noise level and limited mounting space. Provision is made for installation in a premise above the suspended ceiling.

    Design

    The fan casing is made of galvanized steel sheet and provided with heat- and sound-insulating material. Round connecting pipes are fitted with rubber seals.

    Motor

    The centrifugal impeller with backward curved blades is powered by means of asynchronous motor with external rotor. The motors are equipped with built-in thermal overheating protecting with automatic restart. Motor ball bearings with selective lubricants oil ensure low noise and maintenance- free fan operation

    Speed Control

    Both smooth or step speed control is performed with the thyristor or autotransformer controller. The motor speed is controlled by means of power voltage decrease. Several fans can be connected to one controller in case their total power and operating current do not exceed the controller rated values.

    Mounting

    The fan shall be fixed to a building by means of supports, suspension brackets or fixation brackets. The fan can be mounted in any position with respect to the air flow direction indicated with a pointer on the fan casing. Access to the fan maintenance shall be provided.
