Most manufacturing plants use blowers for ventilation and for industrial processes that need an air flow. They are also used to produce negative pressures for industrial vacuum systems. The centrifugal blower and the positive displacement blower are two main types of blowers. Centrifugal blowers are commonly used as industrial blowers. Industrial blowers are large equipments used to move air in a small factory to a large manufacturing unit. Because of high temperatures that range in production units, it affects the working capability of machines and workers. With the use of industrial blowers, such polluted air is thrown out of the unit and new fresh air is moved in. The mechanism of an industrial blower is such that the wheels draw the air inside the structure of the blower and the axial fan throws out the polluted air. Industrial blowers are well engineered and having high efficiency incorporating all the latest technologies. Centrifugal blowers look more like
centrifugal pumps than fans. The impeller of centrifugal blower is typically gear-driven and rotates as fast as 15,000 rpm. In multi-stage blowers, air is accelerated as it passes through each impeller. In single-stage blower, air does not take many turns, and hence it is more efficient. Centrifugal blowers typically operate against pressures of 0.35 to 0.70 kg/cm2, but can achieve higher pressures. One characteristic is that airflow tends to drop drastically as system pressure increases, which can be a disadvantage in material conveying systems that depend on a steady air volume. Because of this, centrifugal blowers are most often used in applications that are not prone to clogging. These are mainly useful in industrial applications. The applications for which Industrial Blowers are used for would be extremely long, the most common include:
• Conveying material in dust collector systems or loading to silos, trucks and railroad cars.
• Combustion air for burners and industrial water heaters.
• Cooling electrical equipment or parts from heat curing ovens and kilns.
• Pressurizing cabinets, vaults or rooms.
• Blow-off systems to remove moisture from parts prior to painting, coating or packing.
• General ventilation of rooms or factories.
• Providing suction or pressure for industrial process air flotation tables.
• Drying ink on cans and bottles, silk screen and printing processes.
