Leesii’s Industrial Fans and Blowers Guide

The manufacturing plants depend on industrial fans and blowers to optimize different environments for quality production processes.  To achieve a desired ventilation, uncontained air must be moved using either a blower or a fan. Some of the common applications include cooling of personnel, dilution ventilation, cooling machines, etc. To ventilate an environment, air must circulate from one point to the other.

To achieve all these functions, it is important that you understand all the basic principles of the industrial fans and blower operation. Through this, you will be able select the best equipment and provide the required maintenance procedures.

The operating fundamentals

Funs and blowers can be classified as turbo-machines that move air through a system. The main difference between these two devices and a compressor depend on the magnitude of pressure it can generate. That, a compressor can produce a pressure greater than 416-in. w.g. On the other hand, a blower can generate a pressure above 30-in. w.g.  Another key factor to consider is the direction in which the direction the outlet air moves relative to the incoming air. Based on this, the industrial fans can be classified as either centrifugal or axial. The industrial blowers are classified as either centrifugal blowers of positive-displacement blowers.

The performance

All the fundamental aspects of industrial fans and blowers are expressed in graphs called the performance curves.  The interpretation of these curves are based on certain laws. For instance, the affinity of a fan tries to derive a relationship that exist between various fan and blower parameters such as the:

1. Fan impeller diameter
2. Density of air or gas
3. Rotational speed
4. Pressure developed
5. Power required
6. Rat of flow

With the help of the fan and blower performance curves, the operation point can be established. The device can then be configured to suit the desired standards. The point where the curves intersect forms the operation point. That is, these devices operate optimally.

A performance curve can be used to establish the relationship that exist between the flow rate and pressure developed at different speeds. In addition to these, the power required and the overall efficiency can be established. All industrial fans and blowers manufactured by Leesii come with the performance information catalog for fan and blower selection.

In any manufacturing process, quality of the final product must be determined. The quality is determined based on the ISO or the ANSI/AMCA standards.

In short, you need to be able to differentiate blowers and understand their performance based on the date represented on the curves.
