What Is The Use Of A Blower?
A blower fan is different from other fans in one major area. Fans will use blades to force out and circulate air, but a blower (which may also be called a centrifugal fan) will have impellers that create a different air movement pattern. Which is right for your application - a fan or a blower? Well, it all depends on the volume and force of air you need.
For general comfort and air movement through work areas, there are industrial fans to fit most every need. But, for environments where hazardous particles may circulate, it is the power of a blower that helps with dust control and keeps the air clear and employees safe.
Why Choose a Blower Fan
For industrial purposes, exhausting flammable dust and flammable fumes is an OSHA requirement for workplace safety. A wall-mounted, circulation fan or pedestal fan is simply not powerful enough to eliminate the dust caused by processes such as sanding, sawing, or cutting of metals, plastics, or timber. A blower can protect the health and well-being of employees by moving air at such a high-pressure and velocity that air particles are virtually sucked out of the environment.
For many industrial environments, blowers can protect electrical equipment from a dust explosion. Pharmaceuticals, paint manufacturing, and the processing of synthetic textiles can generate combustible dust layers in a closed room. A blower fan is the best choice to prevent an explosion that can be caused by an electrical spark from equipment and flammable dust.
When is a Blower Used?
Any process & product cooling operations that require fume extraction may feature mechanical equipment or electro-mechanical devices to improve the safety of workers and protect corporate assets. But blower fans are used for a wide range of functions, including:
- exhausting
- aspirating
- cooling
- ventilating
- conveying
Key differences between fans and blowers are the high amount of power blowers use by creating a pressure differential between air intake and exhaust, and the mechanical movement of impeller blades within the blower housing. A blower may feature multiple blades mounted at a sharp angle and mounted onto a motor hub that is rotated by a drive shaft.
Blowers generate such a high-speed of impeller rotation that they can effectively eliminate a critical product needed for ignition - flammable fumes or flammable dust. For extremely hazardous environments, consider an explosion-proof, high-pressure blower in areas where you need to protect electrical equipment. Not only will this type of equipment cause a fire hazard due to electrical spark, there is also the risk of high temperatures that can ignite flammable fumes.
Many blowers are used to cool electrical equipment and ventilate toxic gases within hazardous manufacturing or toxic processes. A blower will provide more powerful airflow that can be specifically directed towards equipment or away from workers. In the end, if you only need cooling, then choose an industrial-strength fan, but if you need to ventilate toxic air, then a blower is the better equipment
