ABSTRACT:
A filter support tube for use in a filter cartridge including a helical wound wire defining a cylinder and a plurality of reinforcing strips extending generally parallel to a longitudinal axis of the helical wire cylinder and circumferentially spaced from one another about a perimeter of the cylinder. The multiple turns of the helical wire are embedded in the reinforcing strips and extend through it. The wire is coated with a bonding agent to permit the wire to bond to the reinforcing strips and to provide corrosion resistance. The reinforcing strips embedding the wire lock the wire in the desired helical configuration and provide the required column strength for the filter support tube.
