Exploring Pleats, Pleat Counts And Spacing For Industrial Filters

Pleated air filters are critical in industrial settings. Known for superior filtration efficiency due to its design, this type of industrial filter is also tough and robust. However, to truly understand the functioning of pleated air filters, it is key to understand a few important terms associated with it, such as pleats, pleat counts and pleat spacing, which are all addressed in this blog.

What Are Pleats?

In a pleated air filter, the pleat is a part of the filter element itself, which is designed to increase the surface of the filter. It is a type of fold in the filter element to accommodate a large surface area in a compact space. Pleats can be increased or decreased depending on the type of filtration application. Ultimately, the increased surface area of the filter leads to better filtration.

What Is Pleat Count?

With a basic knowledge of pleats, it is easy to understand pleat count. Pleat count can be defined as the number of pleats or folds in a given industrial filter. The pleat count is directly responsible for the increase or decrease in filtration efficiency. Moreover, with the help of pleat count, it is also possible to calculate the total surface of a pleated air filter. 

What Is Pleat Spacing?

An ideal filter should have a perfect balance between pleat count and pleat spacing. Pleat spacing is the gap or space between each consecutive pleat. Therefore, if a filter has a high pleat count by very narrow spacing, then it will have great filtration efficiency, but it will also obstruct air flow, leading to a drop in pressure. Consequently, this will lead to more dust accumulation and can prove to be counterproductive. 

Therefore, it is important to factor in pleat spacing when designing pleated air filters.
