Industrial blowers are mainly used to circulate the movement of air and gas in ventilation applications. Their main function is to replace impure or contaminated air with fresh air by swirling it around. Almost every industry, including agricultural, chemical, medical, oil and gas, automotive, food processing, mining and construction use blowers for different purposes such as drying, reducing heat levels, reducing smoke and odors, processing and controlling gaseous fumes.

Process blowers are manufactured using a range of durable plastics and metals, or a combination of both materials. For example, industrial blowers operating in corrosive environments are usually made of polypropylene because it provides greater structural integrity and corrosion resistance, and will never de-laminate. Typical recommendations in the construction of industrial blowers are - fiberglass for temperatures above 220 degrees, and metal if pressure is above 10 w.g. (water gage).

Industrial process fans include several types such as duct fans, roof and ceiling ventilators, wall mounted fans, pressure blowers, and freestanding units with different mounting options. For extreme conditions and plants, drum fans can be used to move even larger amounts of air. These types of fans come with wheels attached and can be rolled to the area that circulation is needed the most. Some manufacturers even sell just the fan heads for a more freedom and a reduced assembly and cost on the company.

Radial fans are helpful in removing pollutants like dust and metal particles, carbon monoxide, nitrous oxides, sulfur dioxide, sulfuric acid, and hydrocarbon solvents. Plus, industrial electric fans clearly do not use as much electricity as an air conditioner, circulating air and cooling it at a fast rate for a large space. With high-powered, energy-efficient motors, the larger motor of an industrial fan is actually guaranteed to save energy costs.

The size of the blower may be regulated by the size of the environment in which it is to be operated. For instance, some units are big enough to house both the fan and its power supply. Smaller, portable blowers are mainly used for cleanups and in spaces that require temporary circulation or air transfer.

The air movement and control association recognizes three classes of industrial blowers, classified with numerical designation that is based on how the fan is constructed. The United States' specifications for industrial blowers depend on the airflow in CFM (cubic feet per minute), static pressure in inches, water gage, altitude and approximate air temperature. Here's an example:

Industrial Pressure Blower Co. is a supplier of blowers and fan for Pulp and Paper Industries. Tough applications mean tough fans and blowers by Industrial Pressure Blower Co. - a world wide distributor of industrial process ans OEM fans and blowers, as well as fan / blower components; including high pressure blowers, high temperature fans, spark resistant and explosion proof ventilators, tubeaxial and vaneaxial high pressure ventilators. Canada Blower also does existing fans and blowers repairs, re-build, as well as dynamical wheels balancing. High-efficiency impellers result in low power consumption, operating costs, and quieter operation. All metal hardware is completely sealed from exposure to corrosion by incapsulating into FRP or plastic; the steel support frame and motor base are powder coated with a corrosion-resistant finish. In addition to being highly resistant to chemical corrosion, PP fans are self-extinguishing and will not support combustion.
