Product description
Glass fibre wound depth filter cartridge for high capacity industrial liquid filtration
The glass fibre wound depth filter cartridge is designed for demanding liquid filtration applications requiring high dirt holding capacity, stable pressure behaviour and wide chemical compatibility. Manufactured from fine glass fibre yarn wound around a rigid support core, this cartridge provides true depth filtration for effective removal of suspended solids and particulate contaminants.
Glass fibre wound cartridges are particularly suitable for industrial processes involving aggressive fluids or elevated operating temperatures where polymer-based wound cartridges may not be suitable.
Filtration principle
The cartridge operates using a gradient density depth filtration principle. Glass fibre yarn is wound around a central core with decreasing density from the outer to the inner layers. Larger particles are retained on the outer layers, while finer particulates are captured progressively deeper within the media structure.
This filtration principle provides:
-
progressive particle retention from coarse to fine
-
high dirt holding capacity
-
stable differential pressure over service life
-
effective filtration for high solids loading
Contaminants are distributed throughout the full depth of the cartridge, extending operational life.
Media technology and uniqueness
The filter media is manufactured from high quality glass fibre yarn selected for its mechanical strength, temperature resistance and chemical compatibility. The wound construction forms a rigid and stable filtration matrix without the use of binders or adhesives.
Key media characteristics include:
-
glass fibre wound depth structure
-
graded pore density for efficient depth filtration
-
excellent resistance to chemical attack
-
higher temperature tolerance than polymer wound media
This makes the cartridge suitable for demanding industrial environments.
Design and construction
The cartridge consists of multiple layers of glass fibre yarn wound precisely around a central support core. The construction provides mechanical stability, high flow capability and resistance to deformation under differential pressure.
