PDF Plug Fan
The PDF range of plug fans was only introduced to the HVAC industry in recent years. The PDF range of fans are all horizontally mounted, i.e. the motor shaft is in the horizontal position. Units mounted in the vertical position are available, details of which are available on request..
Fan sizes range from 315mm – 1000mm. The impeller is produced in sheet steel, statically and dynamically balanced to ISO1940 and AMCA 204-G4.0 standards with surface protection achieved through powder coating. The impeller hub is available in standard bore sizes to fit directly onto the motor shaft or in the larger motor frame sizes, taper lock bushes are used.
The fans are fitted with high quality foot mounted electric motors in 400volt 50Hz 3phase as standard. Other voltages namely 525volt 50Hz 3phase and 240volt 50Hz single phase (up to fan certain sizes) are also available on demand. All 400volt 3phase motors supplied with the PDF range are suitable for VSD control.
Standard Class F insulation motors are fitted to all units. Special motors such as premium efficiency IE2 and IE3 can be fitted on request. Further treatment to standard motors is also available. All motors have a conveying temperature range of -20°C to 40°C
The complete unit is of a modular design. The framework, supports, motor platform, motor and inlet cone are all bolted together. Mounting lugs are provided for bolting direct to the AHU or used as supports for anti-vibration rubber mountings which are available on request.
