BK Air System is manufacturer different kinds of Centrifugal Blowers in Delhi, UP, 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 etc.
BK Air System, Centrifugal Blowers are well engineered and having high efficiency incorporating all the latest technologies and are made in heavy duty construction with statically and dynamically balanced impellers which gives trouble free performance. BK Air System Induced Draft fan and Forced Draft Fan models consist of completely backward curved, backward curved with self-cleaning and straight blades.
BK Air System fan wheel has backward curved blades and is designed for either clockwise or anti- clockwise rotation. The blades and wheel are aerodynamically formed to ensure highest efficiency.
A centrifugal blower that functions similarity to a centrifugal pump is shown in figure 1. Air enters the centre opening in the housing in an axial direction, then the blades of the rotating impeller force the air radially outward, resulting in an increase in kinetic energy. As the high velocity air enters the volute shaped portion of the housing, some of the kinetic energy is converted into pressure energy for providing the increased pressure necessary to deliver air to the external system. Figure 1b shows the impeller, which contains eight flat-shaped, radial blades. This design can handle flow rates up to 3600 cfm and static pressure up to 20 in. of water.
A centrifugal fan is a mechanical device for moving air or other gases. The terms "blower" and "squirrel cage fan" (because it looks like a hamster wheel) are frequently used as synonyms. These fans increase the speed of air stream with the rotating impellers.
Centrifugal fans are constant displacement devices or constant volume devices, meaning that, at a constant fan speed, a centrifugal fan will pump a constant volume of air rather than a constant mass. This means that the air velocity in a system is fixed even though mass flow rate through the fan is not.
Centrifugal fans are not positive displacement devices. Centrifugal fans have certain advantages and disadvantages when contrasted with positive-displacement blowers. It is used in transporting gas or materials and in ventilation system for buildings. They are also used commonly in central heating/cooling systems. They are also well-suited for industrial processes and air pollution control systems.
A centrifugal blower is a type of air-moving equipment that works by sucking air in a tube-like structure via an impeller and then forcing the air out at an acute angle to the tube. An impeller, a set of blades that spins at high speed inside the blower, is responsible for pressurising and relocating the air. Centrifugal blowers from Centrifugal Blowers Manufacturers in UP, Delhi, India, can function without a housing, as the design doesn't require it to shield the internal components, however blowers with housings are far more common.
The angle at which a centrifugal blower's blades are set determines not only the efficiency and efficacy of the blower, but also the rate at which air is transported through the system. The most effective blades are those with a backwards curve, whereas the least effective are ones with a forwards curve.
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.
BK Air 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 etc. 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).
Like a plane's propellers, the blades of a centrifugal fan are fastened to a hub at the device's centre. Although a fan's blades may be surrounded by an enclosure, this typically occurs on the outside of the fan and has no bearing on airflow.

The Induced Draft (ID) fans and Forced Draft Fan are designed to meet ideal requirement for various industrial applications. BK Air System fans are of sheet steel construction with backward curved self cleaning blades. The self - cleaning efficiency of an induced draft fan will increase when the tip angle of the blade is enlarged. These fans are, therefore, suitable for Kitchen Exhaust, Dust Collector System , Fume Exhaust, Welding Shops, Pharmaceuticals, Chemicals, Engineering Industry, Automobiles etc.
