Product description
Polyester pleated filter cartridge for economical, high efficiency liquid filtration
The polyester pleat filter cartridge is designed to deliver efficient particulate filtration with high flow capacity and low pressure drop. Using a mono layer pleated polyester filter media, this cartridge provides a large effective filtration surface area while maintaining stable hydraulic performance.
The cartridge is suited for a wide range of applications, from natural water sources such as borehole and river water to more demanding chemical process environments.
Filtration principle
The cartridge utilises mono layer pleated polyester filter media to retain particulate contaminants on the surface of the pleats. Process liquid flows evenly through the pleat pack, allowing efficient particle capture while maintaining low differential pressure.
This filtration principle provides:
-
high flow potential with low pressure drop
-
efficient surface filtration
-
uniform flow distribution through the pleats
-
predictable filtration performance
The pleated design maximises usable filtration area within a compact cartridge format.
Media technology and uniqueness
The pleated filter media is manufactured from resilient polyester fibres selected for durability and chemical resistance. The mono layer construction provides an economical solution while maintaining effective particle retention across a wide micron range.
Key media characteristics include:
-
mono layer pleated polyester media
-
high surface area pleat construction
-
good chemical compatibility
-
stable performance over service life
For applications requiring tighter classification or higher efficiency, multi-layer pleated alternatives are available.
Design and construction
The cartridge features moulded vinyl plastisol end caps that eliminate the need for separate gaskets, ensuring consistent sealing and maintaining pleat pack integrity. A robust inner polypropylene core supports the pleated media and prevents collapse under flow conditions.
Typical design features include:
-
pleated polyester filter media
-
integrated vinyl plastisol end caps
-
gasket-free design
-
rigid polypropylene inner core
The construction provides a lightweight yet durable cartridge suitable for repeated replacement cycles.
