Teral-Aerotech’s specialise in the design and manufacturers of centrifugal Blower Fans. The centrifugal Blower Fans designs uses the centrifugal force generated by a rotating disk, with blades mounted at right angles to the disk, to impart movement to the air or gas and increase its pressure. The assembly of the hub, disk and blades is thought as the fan wheel, and sometime includes other components with mechanics or structural functions. The centrifugal fan wheel is often contained inside a scroll-shaped fan housing, resembling the shell of the nautilus sea creature with a central hole. The air or gas within the spinning fan is thrown off the outside of the wheel, to an outlet at the housing’s largest diameter. This simultaneously draws more air or gas into the wheel through the central hole. Inlet and outlet ducting are often attached to the fan’s housing, to supply and/or exhaust the air or gas to the industry’s requirements.
