Inclined Filter 20 (DWZ) SiGMA-Li FS20

Inclined Filter 20 (DWZ) SiGMA-Li FS20 is a replacement filter element designed for filtration systems that require a 20-sized inclined (skewed) cartridge geometry. The element is intended for particulate separation in systems using DWZ-type housings and provides a direct-fit spare or maintenance part to restore filtration performance in industrial and residential installations. The design focuses on compatibility with inclined-surface filter seats and on maintaining flow characteristics specified for 20-sized cartridges.

Advantages

The inclined geometry ensures correct seating and even flow distribution across the filter media, reducing bypass risk in DWZ-type housings. As a spare element, it facilitates fast replacement during routine maintenance and supports consistent particulate capture without needing modifications to the existing system. The unit is suitable for restoring original filtration performance where a 20-sized inclined cartridge is required.

Suitable for

• Replacement of worn or fouled inclined 20-sized filter cartridges in DWZ-style housings
• Routine maintenance schedules in industrial and residential water or fluid filtration systems
• System upgrade projects where a compatible inclined cartridge is needed to match existing flow geometry

Key specifications

• Inclined (skewed) cartridge geometry for DWZ-type filter seats
• Designed for 20-sized filter housings and flow ratings consistent with that size
• Element type intended for particulate separation
• Form factor compatible with direct replacement without housing modification

How to use

Shut down the filtration system and relieve pressure according to the system manufacturer's procedure before attempting replacement. Remove the housing cover, extract the old cartridge, and inspect the housing for debris or damage. Insert the Inclined Filter 20 (DWZ) SiGMA-Li carefully, ensuring the inclined surface seats correctly in the DWZ-type recess. Reassemble the housing, restore pressure, and check for leaks and correct flow. Follow any site-specific commissioning steps to verify system performance after replacement.

Usage recommendations

Replace the element according to the system's maintenance interval or when differential pressure indicates fouling. Use only in systems that specify an inclined 20-sized cartridge geometry (DWZ-type). Store spare elements in a clean, dry environment and inspect seals and housing seats during each replacement to ensure proper sealing and flow.
