BD Series of low pressure centrifugal fans

The forward curved double inlet centrifugal fans are commonly known in the industry as “Inch Blowers” as the impeller is nominally dimensioned by diameter and length: (E.g. the BD- 10/08 has a nominal 10 inch diameter and 8 inch long impeller)

The BD series of forward curved centrifugal fans construction is of a galvanised steel scroll with the impeller in sizes 7/7, 9/9,10/10 and 12/12 and each is produced from Polyamide reinforced with glass fibre with larger sizes in galvanised steel.

The fan/motor are rated to IP55 protection for dust and water ingress. Incorporated into the fan construction are anti-vibration pads which are used on the motor and on the arms to the side plate of the scroll to avoid any vibration and to enable full compliance with “ROHS regulations 2002/95/EC (Restriction of Hazardous Substances in Electrical and Electronic Equipment) .

As standard the BD Fan range is speed controllable by voltage variation, and our REGA range of speed controllers is available on request. Outlet flanges are also available if required.

Product Range

The range is produced in AC voltages, (single phase in 7/7, to 10/10 size, the 12/9 and 12/12 is available in single and 3 phase finally the BD15/15 is 3 phase only) temperature rated to 50C for the single-phase fans and 60C for the 3 phase options.

There is also a range of electronically commuted (EC) BD products called the BD EEC range. This range can run above synchronous speed, dependent on the model at up to 2000rpm to provide higher pressure and airflow for a given size AC equivalent. Speed controllable by either 0-10V DC or PWM (Pulse Width Modification) they also provide an energy efficient solution.

Applications

The BD fan series is used in diverse settings including:

  • Attenuated cabinet fans
  • Air handling units
  • Kitchen ventilation
  • Warm air heaters
  • Special effects for film, television and market
  • Inflatable products and buildings

The range is now available to purchase online here.

We would be happy to work alongside you for specific applications and to work together to produce a fan to the requirements of the installation. Should you want to know more about the ranges of industrial fans we offer, please download our product catalogue or email casals@vortice.ltd.uk.
