There are a few things to keep in mind when choosing the right size axial fan net cover for your needs.
The first is the airflow from the fan. It's important to understand this so you can choose a guard that will allow enough air to flow through.
Air volume is the amount of air that the fan moves in a certain amount of time. It is usually measured in cubic feet per minute (CFM). The higher the CFM, the more air the fan can move.
Many factors affect airflows, such as fan size, speed, and type of guard. The most important factor is the size of the guard opening. If the opening is too small, it will restrict airflow and reduce fan performance.
It is important to choose a guard that provides sufficient airflow for your specific application. For example, if you are using a fan to cool a room, you need much greater airflow than if you use a fan to circulate the air in a small workshop.
Another thing to consider is the type of filter you need. Some filters are more effective than others and help keep the fan running smoothly. The best way to determine which filter is right for your fan is to consult the manufacturer's instructions. In general, though, most axial fans will work with either a compact or enclosed filter.
Finally, you need to consider the size of the available space. This will help you choose a fan cover that is the right thickness for your needs.
