Centrifugal Blowers

We, at BK Air Systems, are centrifugal blower fans manufacturers in UP, Delhi, India as well as suppliers of the same in UP, Delhi, India and other states. The impeller with its characteristic sickle shaped blades is designed for optimal aerodynamic performance and most efficient operation. The use of high-end materials and modern production methods allow for the unique shape of the blades – a factor contributing significantly to the excellent performance of the axial flow fan. A special nano-coating prevents dust deposits during operation to keep efficiency constant at maximum level at all time.

Blowers develop little higher pressure in comparison to fans. They are used for pressure below 1.65 Psi. The centrifugal blower produces energy in the air stream by the centrifugal force and a velocity to the gas by the blades. The scroll shaped volute diffuses the air and creates an increase in the static pressure by reducing the gas velocity. BK Air Systems, are centrifugal blower fans manufacturers in UP, Delhi, India as well as suppliers of the same in UP, Delhi, India other states.

The performance of a centrifugal fan varies with change in conditions like temperature, speed and density of the gas being handled. Corrections must be applied to manufacturing standards with respect to operating conditions.

Sizing the appropriate blower is a three-step process.

• Understand and characterize the system.
• Select a design point.
• Select a blower that can operate at that design point.

Advantages:

• Higher efficiency – lower power consumption
• Aerodynamic aluminum blades
• Corrosion free design
• Higher fan capacity
• Wide range of configurations for best fitting operation point
• Sturdy industrial design
• Nano-coating for increased efficiency
• Reduced noise level
• Adjustable blade pitch angles

For the sake of this post, an aerodynamic system is the piping into or out of the blower. Each length of tubing or pipe, elbow, valve, and nozzle affects this system. A customer may have, for example, a nozzle with which to blow chips from machined parts. The system, in this case, is the inlet to the blower (usually covered by a filter canister), the blower itself, and tubing or hose from the blower to the nozzle. Each component has a resistance, similar to an electrical circuit, that robs some pressure from the system. Valves, nozzles, and elbows tend to have high resistance, while hoses and conduits have low resistance.
