Centrifugal Blowers – Features And Applications

 Centrifugal blowers provide directional airflow by maximizing static pressure. They are particularly useful in industrial and commercial environments where it is not easy to supply air at a uniform rate. 

Their applications range from fume exhaust, dust handling, material conveying, induced draft, forced draft, etc. They are used in a wide range of industries such as foundries; power, cement, and chemical plants; engineering industries, etc. 

A blower’s main function is to provide and accommodate a large flow of air to various parts of the building. It does this by rotating several blades connected to a hub and shaft with the help of a motor or turbine. A centrifugal blower uses the centrifugal power generated by the rotation of impellers to increase the kinetic energy of air. The air then moves from the impellers into the fan housing. Since the requirements of every plant are unique, their centrifugal blowers need to be customized accordingly. 

Ventech Systems, who are leading manufacturers of these blowers, offer a wide range to suit the specific needs of every client. Depending on the requirements, the impellers in their blowers are of various types:

• Backward Inclined
• Backward Curved
• Backward Flat Sloping
• Forward Curved
• Straight Radial

Their fans have 2 types of configuration:

SWSI (Single width, single inlet)

DWDI (Double width, double inlet)

Depending on air discharge and pressure development combinations, single and multiple (parallel or series operation) impellers have been provided.

Here is the size and performance range of Ventech’s centrifugal fans:

• Size: Impeller diameters - maximum 2050 mm
• Airflow: SWSI - maximum 125000 CMH; DWSI - maximum 275000 CMH
• Pressure: Single Stage: maximum 1200 mm.wg. Two-stage: maximum 2500                        mm.wg.
• Temperature: 425 0C

To withstand the extreme conditions these blowers work in, their components need to be strong and durable.  

In the case of Ventech, here are some salient construction features that go in making them tough and long-lasting.

Housing:

• The blowers have a circular air inlet with a rectangular cross-section air outlet port. 
• Continuously welded fan housings.
• Have conical shrouds.
• All housing outlets have a flanged connection.

Impellers:

• Impeller wheels have multi-blade construction; precision balanced as per ISO: 1940.
• Blades of special contour to help them handle varied quality air stress.

What benefits come with using centrifugal fans?

 Many times, we hear about ventilation and air movement in factories, warehouses, and manufacturing units. These are mainly done with the help of Centrifugal fans. Let’s understand what this fan is and how beneficial it is for multiple applications. This fan is typically demanded and utilized for various commercial, residential and industrial applications to move air through the duct. These are the preferred fans for garage and car washing areas. If we will talk about its design then they have got a simpler design as compared to any other fans.

Here’s the list of the benefits of using this fan at different establishments:

• This kind of fan offers amazing aerodynamic properties. Because of this, the centrifugal fan ensures better air movement and is suitable for installation in automobiles and other related systems.
• In terms of efficiency, this fan has no comparison. One of the main reasons for using this fan is its high energy efficiency. In simple words, this kind of fan comes with constant airflow during its operation. Because of this, it can generate energy up to greater efficiency. For maintenance purposes of any air system, increased efficiency is very important.
• When it comes to easy maintenance, the one name that comes to mind is centrifugal ones. These are specially designed with lighter material so they are easy to be installed and cleaned whenever you want to.  Many air systems come with bulky design and require a lot of time in maintenance. As these Centrifugal fans come with some self-cleaning features, you will get complete relief in the daily maintenance.
• One of the concerns that people have related to air systems is the overloading. Is this fan specially designed to bear overloading? The best part is that these centrifugal fans are designed in such a way that they can withstand overloading. These fans are featured with horsepower curves that can easily overcome the problem of overloading if the capacity is exceeded. 
• Another important benefit is that these fans are well suited for longer applications. The moving parts of this fan are enclosed with high-quality material that ensures optimum durability and longer functional hours.

This kind of air system comes with unique attributes that make them suitable for application in various places. Because of all these benefits, there’s a great demand for centrifugal fans for air movement and ventilation. 

Why you should choose an axial flow fan?

 There are many places such as factories, manufacturing units, and other establishments where you can find the application of Axial flow fans. This kind of fan is extensively demanded to improve air pressure and movement. Many people think it is similar to low-pressure fans but these are different. The axial fan is well suited to be used in several places such as in welding for removing the fumes and gases. It also finds its great application in the steel industry and automobile industry where there is a need of exhausting the air. 

One of the main reasons for using this fan is circulating and boosting the flow of air inside the ducts. This fan is useful in increasing the process of exhaustion in multiple places. 

Let's check out some of the important benefits of these axial fans that make people choose them over other air systems:

• One important feature of this fan is the aerodynamic design of the impellers. These help the fan to perform well for the air movement. With this kind of feature, it becomes easy to increase the efficiency of the fans. As this helps in saving a lot of energy, there is a great demand for this fan. 
• Another important benefit of axial fans is their low maintenance. The low maintenance features make it suitable to be used every day without any stress of complicated maintenance. Apart from this, it has a user-friendly interface that ensures its easy handling. 
• Low operational noise is another important feature of axial flow fans because of which these are in huge demand in industrial places. In this fan, there are airfoil designs that help in reducing the noise during its operation. Other than this, it is tested on various parameters to ensure its application in harsh climatic and environmental conditions. 
• If we are talking about the benefits & features of the axial fan then we cannot forget about its longer functional life. Its high and improved mechanical strength has made it possible to use this fan for a longer period.

If you are interested in buying the best quality, affordable and highly efficient axial fans then you must consider choosing Ventech Systems. They ensure high performing flow fans and other similar air systems in varied technical specifications. So, connect with them for a superior range of axial flow fans.
