Filter Media Pleating

Pleating

Fluid Conditioning Products' mission is to provide our customers with custom-engineered solutions for high performance filtration applications. We achieve this mission by meeting rigorous specifications and challenging filtration performance standards. Because of our certified processing capabilities some of our customers ask FCP to perform Special Process sub-contract work, for example Filter Media Pleating, to support their own manufacturing operations.

For some applications it is necessary to enable a much larger volume of gas or liquid to flow through a filter located in a limited space envelope than would be possible using a traditional filter design. In these cases it is necessary to increase the total surface area of the filter medium (gauze or screen). This is done by "pleating" the filter medium, which involves "Z-folding" the material back and forth against itself. Z-folding enables the filter to trap more contaminant particles and so allows faster air or liquid flow rates through the filter assembly.

Pleating

FCP has been pleating filter media for many years. Typical materials include paper, metal wire mesh, synthetic fiber and stranded glass. One current application for pleated filter media is air filters for helicopter engines used in both military and civilian aircraft.

FCP developed and built its own production machines for pleating. The proprietary "reefing" process in use today is fully computer controlled and produces higher density pleats than the previous generation of pleating equipment.
