Centrifugal blowers use high speed impellers or blades to impart velocity to air or other gases. They can be single or multi-stage units. Like fans, centrifugal blowers offer a number of blade orientations, including backward curved, forward curved, and radial.
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 and volume of an air stream with the rotating impellers.
Induced Draft (ID) fans are used to create a vacuum or negative air pressure in a system or stack. Our centrifugal blowers are used to maintain elevated ventilation, resulting in increased system efficiency.
FD fan, which is mentioned here for forced draft fan, is used basically for providing the required quantity of hot air to the furnace for smooth and uniform combustion of fuel. FD fan will produce the positive pressure inside the system i.e. furnace
ID & FD Fan Place in Furnace
This picture depicts the placement of ID and FD Fan in the Furnace.A fan is used to force air into the boiler to provide more air for combustion.
Feeds combustion air to secondary boiler, acts as ID fan or FD fan according to its position and arrangement. We provide heavy duty centrifugal industrial fans. These fans are of high efficiency.
Tube Axial Fan
These are axial fan units with fan wheels located in cylindrical tubes, without inlet or outlet dampers. Vaneaxial fans – These axial flow fans have a higher pressure capability due to the presence of static vanes. ... These fans are often used in mining applications.
Man Cooler Tube Axial
With the increased use of technology, each and every manufacturing has turned automated which has in turn result to increased use of machinery that emits heat and risen the temperature inside a production unit which may be a small factory or a large manufacturing unit. Workers health and well being are very important for their consistent workability. Man coolers are designed to provide fresh air in muggy and dusty surroundings which is very important to maintain the health of workers. The mechanism of man coolers produce high velocity cool air stream passing over a long distance, which helps to vaporize perspiration and thereby keep the body cool.
Distributed air must be clean, provide the proper amount of ventilation, and absorb enough heat to cool the conditioned spaces. To deliver air to the conditioned space, air carriers are required, which are called ducts. Ducts work on the principle of air pressure difference. If a pressure difference exists, air will flow from an area of high pressure to an area of low pressure. The larger this difference, the faster the air will flow to the low-pressure area.
