Klir Di-4 Waste Spindle Replacement

Klir Automatic Fleece Filter 4-Inch Waste Collection Spindle (SKU: CV-KLIR-4WST-SPNDL)

The Klir Automatic Fleece Filter 4-Inch Waste Collection Spindle (SKU: CV-KLIR-4WST-SPNDL) is an authentic structural OEM replacement hardware component distributed by CoralVue to preserve consistent mechanical filtration and prevent motor tracking failures. Automatic drop-in roller filters serve as a highly effective substitute for traditional cloth socks, continuously advancing a 50-micron non-woven fleece roll across the sump's drain path to capture suspended particulate matter before it can break down into nitrates and phosphates. While the fresh fabric unspools from a clean rod at the rear, this heavy-duty motorized waste spindle pulls the dirty material up and rolls it out of the water column. Because this spool features critical gear-mesh teeth and must be manipulated during every single media refresh, it is highly vulnerable to stress fractures, gear-stripping from manual force, or getting misplaced during a deep aquarium tear-down. Replacing a broken or missing core with this original factory spindle instantly restores absolute drive authority.

Molded to meet precise engineering thresholds, the CV-KLIR-4WST-SPNDL is calibrated strictly for the tracking channels of the Klir Di-4 Automatic Drop-In Filter. Unlike universal aftermarket rods or makeshift DIY pipe solutions that fit loosely, this factory spindle locks the rolling fabric perfectly square with the primary web path. This precise alignment stops the wet, heavy fleece from drifting sideways, wrapping lopsidedly, or bunching up against the acrylic housing side plates. By maintaining a uniform compression profile across the motorized web, it ensures the optical level sensors trigger exact advances, optimizing total media life and preventing unfiltered bypass water leaks around your sock tray.

Key Features

• Restores Positive Motorized Drive: Ensures zero slippage between the 12V DC motor gear and the collection core, pulling heavy, sludge-laden fleece easily.

• Handles Heavy Saltwater Moisture: Closed-polymer configuration won't expand, degrade, or seize up under continuous exposure to humid sump atmospheres.

• Instant Slip-In Media Swaps: Lifts cleanly straight up and out of the tracking tracks, letting you clear out dirty, spent rolls in seconds without turning off plumbing valves.

• (Note: This retail SKU contains (1) single standalone replacement motorized waste collection spindle. Smooth clean roll spindles, replacement 50-micron fleece rolls, swappable sump collars, clear vent tubes, and 12V DC motor blocks are sold under separate product categories).
