High Velocity Fans
High velocity fans are blower systems which provide high levels of air and gas movement in ventilation, circulation and drying applications. Generally more powerful than most other types of fans, high velocity fans can deliver air speeds two or three times greater than ordinary pedestal or box cage fans. Due to their ability to penetrate long distances and provide evenly distributed air flows, high velocity fans are ideal in applications in which continuous, consistent air movement is required. These applications include product cooling, air circulation, drying, facility ventilation, dock cooling, assembly line cooling, and mezzanine ventilation. Industries that benefit from high velocity fans include agriculture, industrial, commercial, distribution, automotive, medical, food processing and residential.
High velocity fans are typically completely metal constructions; the fan is metal and the blade is metal. Used to circulate the air, blade sizes can range from 12" to 30"and are confined in a metal housing. High velocity fans also have a sealed motor and a grounded cordset. The motor can be between 1 - 3 horsepower and is mounted to the back of the fan's hub, or the point on a high velocity fan wheel from which the fan blades extend, where it is permanently lubricated along with ball bearings and a pull chain and then the motor is encased by metal. The sealed motor is connected to a power supply source by the grounded cord set, or an attachment to the motor that serves as the means of supplying electricity to the high velocity fan. High velocity fans can come in both oscillating and non-oscillating models.
High velocity fans come in a wide range of sizes and shapes. Some units are mounted into the framework of a system or piece of equipment, complete with vibration absorbent mounting brackets which house both the high velocity fan itself and its power supply. Portable high velocity blowers are much smaller and are transportable from place to place for use in temporary circulation or air transfer, such as at construction sites or when cleaning up spills and water damage. Some different areas that high velocity fans can be mounted include walls, panels, ceilings, roofs. Depending on the where the high velocity fan is to be mounted, different mounting styles are applicable such as chain, yoke, wheels, wall/column, truck or pedestal.
