Filtration is based on depth filtration: fluid passes through a wound fibrous structure where particles are captured within pores of varying sizes.
The gradient structure allows:
• retention of larger particles in outer layers
• capture of fine particles in inner layers
• reduced clogging rate
Cartridges are manufactured by winding fibers around a central core.
Main materials:
• polypropylene
• cotton
• fiberglass
The design allows different combinations of media and cores depending on operating conditions.
Main parameters:
• filtration rating — 0.5–150 μm
• filtration type — depth (nominal)
• low pressure drop with high flow rates
• wide chemical compatibility
Applications:
• water treatment
• chemical and galvanic processes
• filtration of solvents and oils
• condensate and seawater treatment
