All industrial setups with manufacturing and processing equipment require proper ventilation for the customers and the employees. The industrial fans enhance the movement of gases and air necessary for the optimal working of industrial sites. They are handy for those who need to get rid of odours from the workspace while introducing fresh, habitable air. Generally, industrial fans are versatile enough for various industries including chemical, agricultural, food processing and mining. In this piece, you will learn about the primary components of industrial fans to help you make the right purchase and installation decisions:
The Drive System
The drive system is one of the critical components of an industrial fan. Usually, you can get two types of drive systems. The first one is a direct drive system that features a fan attached to a motor shaft. The setup is simple and efficient but less versatile when it comes to adjusting the speed. Most of the direct-drive systems rely on induction motors with synchronous speeds. This setup increases the sensitivity of the fan's output, and the chances of making an error are high for those who need to estimate the fan's performance requirements.
On the other hand, you can opt for belt drive systems whose top benefit is better flexibility of the fan speed. Axial industrial fans use their belt drive systems to eliminate the motor from the airstream. This element makes them suitable for dirty, corrosive and high-temperature fan applications.
The Piping or Ductwork
Industrial fans need pipes or ducts to direct air into and out of the target space. Typically, there is a difference between ducts and pipes. Ducts are made using thin sheet metal, and they are ideal for low-pressure fan systems. On the contrary, pipes are made using sturdier materials that can withstand high-pressure applications.
The rule of thumb is to go for the largest possible ductwork for your particular application. Large ducts may have high installation costs, but you will offset that through lower energy costs. There is a better movement of air through larger ducts because of low friction.
The Air Control Devices
The last components discussed here are the air control devices. These comprise inlet vanes, outlet and inlet dampers. These components work together to regulate the fan's output. They make the air swirl as it hits against the fan blades. They also throttle the air and restrict the volume of air that finds its way to the fan. These two actions create a balance between energy efficiency and air conditioning of the space.
