Centrifugal Fan
Belt-Driven Centrifugal Cabinet Fan AW SeriesSystemair’s range of centrifugal fans offer the engineers the flexibility to choose the most suitable sizes and configurations to suit any site condition. With over 2000 variations of diameter, width and impeller type, specifications are virtually tailor-made to individual needs. We offer both single and double inlet forms and in three classes of construction to suit almost any applications.
There is a choice of eight impeller types, providing optimum performance to meet any duty. Casings are made of mild steel, welded and many are of semi-universal construction allowing the discharge angle to be modified to suit customer’s requirements. Many additional features and ancillaries can be supplied on request, example; split casings, carbon steel and stainless steel impellers.
Centrifugal Fans – Types of Blades
There are many different types of Centrifugal Fans covering air volumes from 50 CFM to 60,000 CFM and from 0.1 inches water gauge to 60 inches water gauge. Each application requires a fan with different characteristics, whether it be the blade design, the width of the casing or even the method of drive. By way of a guide as to which is the best for certain projects, we list below information that might assist the potential user.
Paddle Blades
This type of fans is used for the conveying of dust, woods and paper refuse, cotton fly etc. Since the blade design prevents ‘Build up’ of waste materials, discharge velocities vary dependent upon what is being conveyed in the air- stream. Normally in the region of 1500-4000 feet per minute.
Multivane or Forward Curved Blades
Used for general ventilation purposes – not good for dust, etc. Limited pressure characteristics. Normal discharge velocities 1000-2500 feet per minute.
Backward Curved or Backward Inclined Blades:
Non-overloading power characteristic suitable for very light dust applications (e.g. clean side of dust collector) where a good efficiency is required. Used for high pressure ventilation systems or where the system resistance could fluctuate. Normal discharge velocities 1800-3000 feet per minute.
High Pressure Blowers:
As their name suggests, these fans are supplied where the requirement is for high velocities, e.g. Air curtains, refuse conveying, etc. Normal discharge velocities 3000-6000 feet per minute.
Special Note:
Since Forward Curved and Paddle Blade fans have overloading power characteristic it is important the selected static pressure is achieved. Any reduction in the requirement could easily overload the motor.
