Industrial fans are used in the following industrial fields:

They are also used in heating plants and incineration plants, where they form a part of evaporators. They supply compressed air to the incineration furnaces. Hot air industrial fans, ATEX fans as well as other fan types are available.
Industrial fans form a part of the equipment for cooling, degassing, vacuum distillation, moisture removal or freeze drying. They form a common part of ventilation systemswhere they serve as circulation air.sources They are used to ventilate rooms and workplaces, such as painting facilities or welding workshops. They are not affected by slightly volatile pollutants, and they can ventilate air from the galvanizing baths.
Industrial fans and blowers with side ducts create a vacuum that can be used for positive or negative pressure handling. Vacuum pressure can be distributed with the help of air nozzles, so that large areas can be gripped. In the printing industry they are used, for example, in paper handling systems and in the textile industry in weaving and knitting machines.
Many dust particles and gases are already highly explosive in their original state. ATEX-modified industrial fans are also deployed in more demanding environments. In chemical factories, biogas plants, mills, landfills, wastewater treatment plants or flour silos.
In agriculture , industrial fans supply pressure for the transport of granular and bulk materials in pressurized operations. They are used in feeding devices and dispensers for transporting feed, feathers, powders or tobacco. They form an integral part of dosing machines and composting plants.
Fans play a key role in aeration (introducing air into the less oxygenated material layers). They are used for aeration of water in breeding tanks, backwashing of filters and water oxygenation. In wastewater treatment plants , industrial fans are used in filtration units for aeration and blowing.
Fans can be used in spa facilities, saunas and SPAs, where they are used as air sources for whirlpools.
Food processing technology uses airflow to blow out (discharge) a variety of media. Fans are applied here as air sources for drying in laundry facilities and dryers.
Fans have their place as a source of pressure and vacuum for the moving shipments in pipeline mail.
Air drying is one of the safest ways to preserve a product. Because of their design, the fans can work with heated air (up to 230 °C). Their use in air weldingor drying of synthetic granulate is therefore common.
