Industrial or mechanical fans come in many different shapes and sizes to suit all industry needs. They can be bought fully assembled, or ordered and tailor made to suit specific needs. Before deciding on what fan to purchase or hire, it’s best to acquaint yourself with the different types and uses of these industrial fans, an essential without which modern industries couldn’t exist the way they do now.Axial FansAxial fans are generally used where the main requirement is a heavy air flow. Common applications include power stations, environmental protection, and high-speed locomotives.The fans use axial forces to function. This allows for movement of air or gas that turns the central hub with blades that expand towards the outer edge.There are various types of the axial fan available on the market, each of which are suitable for certain settings and industries. These include high-temperature axial fans used in industrial convection furnaces, variable pitch axial fans common in the mining industry, and vaneaxial fans that boast a higher pressure capability.Cooling FansCooling fans are used in applications such as radiators, air-cooled heat exchangers, air-cooled steam condensers, wet mechanical cooling towers, and similar. They are, in fact, a type of axial fan, however are common enough to be categorised separately.These devices typically feature larger diameters for low pressures and large volumes of airflow.Centrifugal FansCentrifugal fans are most often used in situations where both flow and higher pressures are needed. They are commonly used in the automotive industry, building ventilation systems, and central heating systems.This kind of fan uses rotating impellers to increase pressure that in turn moves air or other gases. It’s a robust, quiet and reliable piece of equipment.There is a vast range of centrifugal fans available to buy or hire. These include pressure blowers often used in furnaces, airfoils widely used in industries ranging from paper to chemical to incineration, and specialty process gas blowers designed for use in high pressure petrochemical processes.Centrifugal fans are usually cheaper than axial fans as they are more straightforward to produce.Before investing in any industrial fans, consult industry experts, and be prepared to answer questions about your requirements, the setting in which the machinery will be used, and health and safety. You’ll make your own life easier by getting to know the basics of what makes each fan different, and acquainting yourself with some of the industry-specific vocabulary.
