Patent ID: 8252187

Claim:
An apparatus for separating magnetic and non-magnetic particles from water in a domestic central heating system, comprising: a housing having an inlet and an outlet and an upper and lower end, and a magnet located within the housing, wherein the inlet and the outlet are arranged so that, in use, water flows through the apparatus in a cyclonic motion from the inlet downwardly proximate the walls of the housing, and then upwardly within the downwardly flowing water, to the outlet, wherein the housing is configured so that particles entrained within the water separate out by vortex separation as the water flows downwardly, and wherein the magnet is arranged so that magnetic particles entrained within the water are collected by the magnet as the water flows upwardly, the apparatus further comprising: a sleeve located within the housing such that an outer circulation channel is defined between the housing and the sleeve, the magnet being located within the sleeve such that an inner circulation channel is defined between the sleeve and the magnet, wherein the inlet is arranged to deliver the flow of water into the outer circulation channel and wherein the outlet is arranged to exhaust the flow of water from the inner circulation channel.
