In today’s fast-paced world of commercialization and industrialization, efficient air movement is essential for maintaining indoor air quality, cooling machinery, or cleaning the units. To serve this purpose we use Air Blowers. WTB BUSINESS INDUSTRIAL HUB
INDUSTRIAL AIR BLOWERS are electrical devices used to move air for efficient movement and flow of air or gas for various applications. These devices increase the velocity of air and gas through their quipped impellers. They are used for cooling, ventilating, conveying, and exhausting. Air blowers are commonly known as centrifugal fans. In these devices the inlet pressure is low and outlet pressure is high. The blades fixed in between increase the kinetic energy at the outlet. Blowers are used for moderate pressure requirements, where pressure is less than the compressor but more than the fan.
How Does Industrial Air Blower Work- The Principle
- A rotor/ rotating impeller creates a vacuum, the vacuum makes the air rush into the blower. At the Centre of the impeller, the air enters and gets divided by the blades rotating by the rotor. The centrifugal force generated by the movement increases air speed and volume.
- The impellers transfer kinetic energy to the air. The pressure builds up the volume of the air inside the housing. This air is then discharged towards a defined point.
- This channeling of air towards a particular direction differentiates it from a simple fan. Air blowers create a balanced airflow reducing the waste caused by the generation of excess volume and pressure.
Parts of An Industrial Blower
Industrial blowers are very complex machines consisting of several components that work together to replace air effectively. It is essential and a necessity to understand the key components of industrial air blowers for proper maintenance and optimizing the functioning of these big machines.
- Casing or Housing
It encloses the internal components of the blower, keeping them safe from any damage and containing the airflow. These are typically made from durable metals such as aluminum or steel, it generally depends on the environmental conditions and application of the blower.
- Impeller (Rotor)
It is the rotating part that moves the air by converting the mechanical energy into fluid motion. These are designed according to the application and performance characteristics. It can be axial or centrifugal. These are commonly made up of specialized plastics for corrosion resistance, aluminum, or steel.
- Motor
It provides the mechanical energy needed to drive the impeller. These can be pneumatic, electric, or hydraulic based on the application needs and availability of power source. It has the features of adjustable performance and variable speed drivers (VSD).
- Bearing
Bearings are used to support the rotating shaft and to reduce the frictional force between the parts. This ensures efficient operation and smooth functioning. It includes all types of bearings selected based on speed requirements and load. It can be roller bearings sleeve bearings, or ball bearings.
- Shaft
The function of the shaft is to connect the motor to the impeller, transmitting the mechanical energy from the motor to the impeller. The shaft is made up of durable material that can withstand strong rotational and mechanical forces e.g. High ? strength steel.
- Filters
The function of filters is to remove any particulates or contamination from the air entering the blower and protect the internal components. It includes HEPA filters, pre-filters, or any other special filters based on the needs.
- Dampers and Valves
They control the flow of air, allowing adjustments to the volume and pressure needed. They can be of automatic or manual types, depending upon the precision needed.
- Cooling System
Cooling systems prevent any overheating of the device and ensure safe and reliable operation. Its function includes water cooling, air cooling, or specialized cooling.
Key Features
- FLOW RATE: The volume of air is measured in units of cubic feet per minute (CFM) or liters per second (L/s).
- PRESSURE: It is the force by which the blower moves the air, it is measured in inches of water gauge (WG) or pascals (pa).
- POWER CONSUMPTION: the electrical power used by the blower is measured in watts (W) or horsepower (HP)
- NOISE LEVEL: the noise produced by the blower is measured in decibels (dB).
Consideration For Selecting an Air Blower
Before buying an Air Blower one should consider the following things:
- REQUIREMENTS: It is the most essential part of selecting an Air Blower. You must be clear about what you need it for. The specifics, the airflow, pressure environmental conditions, etc.
- EFFICIENCY: choose the Air Blower that gives the necessary performance while minimizing energy consumption and not creating any disturbance in the other operations.
- NOISE LEVELS: Where noise levels are a concern, such as residential areas, and offices, it is better to go for a device that is low noise. In the environments noise levels are crucial.
- MAINTENANCE AND DURABILITY: choose the options that are easy to maintain and not too delicate. It is important to consider the industrial conditions where downtime can be costly.
- COST: The cost of a blower in long-term operations and expected lifespan to ensure a cost-effective solution.
