Magnetic filter with drain and removable external magnetic element
First Claim
1. A magnetic filter for a central heating system, the filter including a connection assembly, a canister, and a magnetic element,the connection assembly including an inlet and an outlet for connection to a central heating circuit;
- the canister having an interior separation chamber which is fluidly connected with the inlet and outlet for allowing fluid to flow into the inlet, through the separation chamber, and out of the outlet; and
the magnetic element including at least one magnet array made up of magnets being removably positionable on the outside of the canister, wherein each magnet array includes at least one magnet pair, each magnet pair including a first magnet positioned with its north pole facing the canister, a second magnet with its south pole facing the canister, and a soft ferromagnetic strip disposed across the north and south poles on the side of the magnets in the pair which faces away from the canister,the canister and the connection assembly forming a sealed flow path comprising the inlet, the interior separation chamber and the outlet, and the connection assembly further including a closable drain outlet for draining fluid and magnetic particles from within the canister to substantially empty the canister.
