Product Overview
Depth Filter Cartridges and Modules are engineered for critical particle removal in liquid processes characterized by high dirt loads or unstable feed conditions.
Unlike surface filtration, depth filtration captures contaminants throughout the entire thickness of the filter media. This multi-layer matrix significantly improves dirt-holding capacity, prevents premature surface blinding, and extends operational service life. These products are widely utilized in clarification, pre-filtration, and fine filtration stages.

High Dirt-Holding Capacity: The graded-density, multi-layer depth structure traps particles throughout the media, reducing system downtime and extending service intervals.
Stable Downstream Quality: Consistent retention efficiency ensures steady filtrate quality, protecting sensitive downstream equipment.
Low Clean Pressure Drop: The optimized, high-porosity fiber matrix maintains excellent flow rates while minimizing initial system resistance.
Broad Chemical Compatibility: Available in a diverse selection of materials suitable for acids, alkalis, aggressive solvents, and complex process liquids.
Rugged Mechanical Strength: Reinforced thermal-bonded construction guarantees structural integrity under fluctuating pressures and demanding operating conditions.
Polypropylene (PP): Graded-density depth media for broad chemical resistance.
Glass Fiber: High-efficiency media for fine filtration and sub-micron clarification.
Polyester Fiber Blends: Enhanced thermal and structural properties for specialized applications.
Multi-Layer Thermal-Bonded Structures: Zero binders or adhesives to minimize extractables.
Pharmaceutical & Bio-Pharma: Cell culture clarification, plasma fractionation, and pre-filtration for sterile stages.
Food & Beverage: Clarification of wine, beer, spirits, juices, bottled water, and edible oils.
Fine Chemicals: Purification of solvents, catalysts recovery, inks, paints, and specialty chemicals.
