AC blower fans are widely used in homes and commercial places, as well as industrial units, and are more preferred over DC fans. These fans are designed to increase the velocity of air or gas that passes through the impeller. They are suitable in applications which require constant and high air pressure as they help maintain the required speed. Sofasco International is a well-known Industrial AC blowers manufacturers, designer, and distributor. We make RoHS certified and cost effective AC blower fans in a wide range of materials, performance characteristics, and functionalities.

- They have a good energy efficiency and hydraulic efficiency.
- They are designed to be durable and can resist corrosion and harsh environments.
- Our fans have temperature control features and can also restrict the motor from overloading.
- They are mostly lightweight, easy to use, and low on maintenance.
- They are especially useful in moving low volumes of air with a huge force.
Applications of High Pressure AC Blower Fans
AC blowers are suitable for high air pressure or constant speed applications. They find applications in the following areas:
- Manufacturing units
- Computers and network servers
- Telecommunication devices
Working Principle of AC Radial Blower Fans
The working of a radial blower, commonly known as a centrifugal blower, is similar to a compressor. The main purpose of a radial blower is to take a low-pressure air stream and deliver a high speed, high volume air stream in a radial direction to the rotation axis. To achieve desired results, the AC radial blowers are designed to function in the following way:
- As an initial step of working of an AC radial blower fan, the low-pressure stream of air enters from an inlet valve in a direction parallel to the axis of rotation.
- From the inlet valve to the tip of the impeller, the air travels in a forward linear direction. However, from the central tip of the impeller, the air takes a 90˚ turn along the surface of an impeller.
- The air glides through the impeller blades as a result of centrifugal action. The result of centrifugal action can be either increase in the speed of the impeller due to air pressure or a speed rise due to the centrifugal rotational motion of the impeller blades.
- As the air travels from the central tip of the blade to the end tip of the impeller, it is forced to enter the casing area of the AC blower fan.
- From the casing, the high volume of air is delivered at high speed as an output.
