What are the different types of fans?
There are many different types of fans including axial fans, centrifugal fans, backward curved fans (also known as plug fans), high performance fans, high efficiency fans, electronic cooling fans (muffin fans), explosion proof fans, box fans, tube fans, roof fans, air curtains and more. Within the various fan types there can be additional choices of motor type, CFM airflow, fan guards, motor mounts, and many more. Zauderer Associates will provide you the expertise that you need to navigate the many choices and options.
What is an axial fan?
An axial fan causes air to flow through it in an axial or parallel direction to the shaft where the fan blades are attached. The axial fan is the oldest design of a fan. An axial fan is commonly used where you have low static pressure and DB’s are important and are well suited for general purpose applications. Axial fan types can include AC, DC, or EC motors. The type of axial fan that you need depends on the voltage value available and whether that is fixed or can fluctuate. Some of the advantages of an axial fan include their dependability and that at a low static pressure and at a low power input, high airflow can be provided.
What is a centrifugal fan?
A centrifugal fan is used with higher static pressure and when DB’s is not as important. The advantages of a centrifugal fan include high efficiency, durability, and versatility.
What is the difference between axial and centrifugal fans?
Neither an axial or centrifugal fan is better than the other, but it rather depends upon the end use and application for the fan. Axial fans tend to have low pressure airflow, require less power input, moves a larger volume of air, and tends to be smaller and less expensive. Centrifugal fans are typically more energy efficient, more durable to environmental factors, creates high-pressure airflow, and moves a smaller volume of air.
What is the difference between backward and forward curved fans?
The primary difference between backward and forward curved fans is the impeller’s rotation. A forward curved fan has smaller blades facing in the direction of rotation. Backward curved fans have longer blades and usually face away from the direction of rotation. Forward impellers provide more static pressure than axial fans. Backward curved fans are generally the most compact and energy efficient fans and can often reduce operating costs.
What is the difference between AC, DC and EC fans?
The difference between AC and DC fans is that AC fans only operate at one speed unless you install an expensive VFD drive to change the fan speed. EC fans can be run at many speeds, can run on 1 phase or 3 phase power, and can be set up to run on constant CFM or constant pressure. EC fans are more efficient than AC fans but are more expensive than AC fans.
What are Industrial Fan Blade Materials and finishes?
Whether one piece or riveted, industrial fan blades can be made of many materials including carbon steel, galvanized steel, galvalume, stainless steel, and aluminum. Finishes for fan blades can also include enamel paint, aluminum paint, zinc plating, hot dipped galvanizing, and epoxy paint.
