Pleated filter element for air filter

Abstract

The present disclosure relates to a pleated filter element comprising: a pleated filter media comprising a main upstream face and a main downstream face, and comprising a plurality of oppositely facing pleats extending between the main upstream face and the main downstream face, the pleated filter media includes a first corrugated edge and a second corrugated edge and a first non-corrugated edge and a second non-corrugated edge, where the pleated filter media includes a main pleat section and a first edge pleat section at the first non-corrugated edge, where the first edge pleat section is located at the first non-corrugated edge, and where the second edge pleat section is located at the second non-corrugated edge. The length of the first edge pleat section is less than 50% of the total length of the pleated filter element between the first non-corrugated edge and the second non-corrugated edge, and / or wherein the maximum pleat height in the first edge pleat section is less than the maximum pleat height in the main pleat section. The present disclosure also relates to an air filter comprising a pleated filter element in a housing.

Description

[0001] Field of Invention [0002] The present invention relates generally to air filters and, more particularly, to pleated filter elements for use in air filters. Application examples include air inlet filters for buildings, gas turbines, etc. [0003] Background of the Invention [0004] Air filters comprising pleated filter elements arranged in a frame structure are used in a wide variety of applications. Air filters are used in a wide range of applications, from air intake filtration in building ventilation systems to air intake filtration in large industrial facilities and equipment. Air filters are typically configured to be mounted in a filter retention structure. The filter holding structure may, for example, comprise a filter housing or filter bank grid with one or more openings in which the filter fits. [0005] Examples of filter types include: panel filters, deep pleated box filters, and V-type filters. Panel filters typically comprise pleated filter elements a...

Problems solved by technology

This can be challenging as the space available to add adhesive is very limited and any modification to the frame construction usually has to be at the expense of the amount of filter media and / or the open area of ​​the filter frame, resulting in pressure drop Increase
