Tucker 4" x 30" Pre-Filled DI Filter Cartridge

What it is

The Tucker 20066-DI 4" x 30" DI Filter Cartridge is a pre-filled DI filter cartridge for pure-water window and solar panel cleaning systems. It comes filled with Tucker virgin DI resin and is a one-time-use cartridge: when the resin is spent you replace the cartridge.

What it fits

It is the replacement DI post-filter for the Tucker 4060 4-Stage RO/DI cart and both H2Pro carts, and it also fits the Tucker T-DI mobile DI system and 4" x 30" housings from many other manufacturers. If you would rather refill with bulk resin, the 4" x 30" Refillable DI Filter Cartridge fits the same housings.

When to change

Tucker's manuals say a fresh DI stage should read 0 ppm TDS and that the reading climbs slowly as the resin is used up. Spotting on glass begins once TDS rises above 10 ppm, and non-glass surfaces can typically be cleaned with water up to 40 ppm, so check your output with a TDS meter.

Tucker doesn't warrant the 4" x 30" Pre-Filled DI Filter Cartridge, because filters, RO membranes, DI resin and other filtration components are consumables. Contact us if it arrives damaged or defective.

The 20066-DI is the 30" member of Tucker's DI cartridge range: the 4" x 21" Pre-Filled DI Filter Cartridge suits the Compact, the 4" x 40" Pre-Filled DI Filter Cartridge suits 40" housings, and the 4" x 30" Refillable DI Filter Cartridge holds 1/5 ft³ of bulk resin.
