Judo Mafi

Sidestream Magnetite Filter

The Judo Mafi takes Judo's larger inline magnetic sludge seperator (Ferroclean) and miniturizes the technology into a powerful sidestream filter.

Mafi Magnetite Sidestream Filter

Product highlights

  • Magnetite and air seperator in one unit
  • No consumable filters - cleans easily in place
  • Pipe sizes from 3/4" to 1-1/2"

How the Mafi works

The Mafi magnetite sludge and air seperator is a small but powerful addition to your mechanical system. It installs as any sidestream filter does and is used to remove magnetic sludge from decaying iron-based piping systems.

As the sludge starts to build-up in your heating or chilled system, it causes significant damage to mechanical components such as boilers, pumps, seals, heat exchangers, valves, sensors, nozzles, etc.

The mafi removes that magnetic sludge with three powerful, rare earth magnets.

The filter uses centrifugal water flow and the magnets to remove large debris and magnetic particles. The magnets trap the sludge in the filter until it is time to clean it. No disassembly is required, you simply close a valve on the outlet, pull the orange clip forward to disengage the magnets and open your drain valve to rinse the unit for a few seconds.

The Judo quickset rotary flange fitting kit allows the unit to be easily retrofitted to pipes and flows that are either up, down, left or right.

No consumable filters, no ongoing maintenance costs.
