The airflow direction makes the first and most noticeable difference: clockwise versus counter clock wise.
Centrifugal fans, by drawing in and then thrusting the air forward, increase the velocity of the surrounding air. The air is blown in a direction perpendicular to the axis of the fan’s centre. A centrifugal blower will take in air from its surroundings and then rotate that air 90 degrees. The impeller, which is shaped like a cylinder along with blades cut into its sides, increases the air’s velocity so that it exits at a far higher rate than it entered.
Safe Enviro System is manufacturers and suppliers different kinds of centrifugal blowers in Delhi, India. These fans are available in different configurations – Double inlet double width, Single inlet single width and Inline duct fans with different impeller blade profiles.(Radial blades, backward inclined, backward curved, aerofoil, forward curves, padel type etFFc. to meet different duty conditions with low pressure, medium pressure and high pressure applications) Impellers can be offered in different materials such as mild steel, stainless steel, MS FRP lined, MS Rubber lined. Fans are also offered with different surface treatments such as epoxy paint, spray galvanizing, hot dip galvanising (up to certain areas).
