These fans are designed for direct or ducted ventilation in residential, commercial and industrial buildings
The range comprise 7 sizes with different speeds and air volumes up to 33.120 m3/h
Composition
The Weather cap and base are moulded in ultra violet stabilised polyester resin, glass reinforced, and fire retardant.
The caps are secured to the mounting brackets by stainless steel screws.
Anti-backdraught shutters
Shutters are of aluminium. Synthetic rubber buffers are provide the ensure quiet operation.
The impeller is aluminium and of Woods patented design. Air is discharged radially, thus eliminating the losses which occur when a vertical airflow is converted to a horizontal discharge by the weather cap.
Totally enclosed motors squirrel cage induction type, for direct on line starting. Protection IP55 – Insulation class F – with overheat protection. They comply to IEC34-1.
Supply: 230V 1ph 50Hz or 400V 3ph 50 Hz
The motor is equipped with a thermal protection.
