Product description
Absolute rated glass fibre pleated filter cartridge for high efficiency liquid filtration
The glass fibre pleated filter cartridge – absolute is designed for applications requiring consistent, known and absolute particle removal combined with high flow rate capability. Manufactured using high strength borosilicate glass fibre media, this cartridge delivers superior filtration efficiency compared to standard pleated polymer cartridges.
The rigid pleated construction ensures reliable performance in demanding process conditions without compromising media integrity or flow performance.
Filtration principle
The cartridge utilises pleated borosilicate glass fibre filter media supported by two rigid support layers. Process liquid flows evenly through the pleated structure, where particles are retained according to the absolute micron rating of the cartridge.
This filtration principle provides:
-
absolute rated particle retention
-
consistent and repeatable filtration performance
-
high flow rates at low pressure drop
-
predictable pressure behaviour over service life
The pleated configuration maximises filtration surface area while maintaining structural stability.
Media technology and uniqueness
The filter media is manufactured exclusively from borosilicate glass fibre, selected for its strength, uniform fibre structure and excellent filtration efficiency. Two rigid support layers reinforce the media, allowing operation at elevated flow rates without deformation or fibre migration.
Key media characteristics include:
-
borosilicate glass fibre filtration media
-
absolute rated particle removal
-
reinforced pleated structure with dual support layers
-
stable efficiency across the full service life
This construction makes the cartridge suitable for critical filtration duties where absolute performance is required.
