Plastic transmission filter

The transmission filter made from a plastic (1), It consists of union with the upper part shell made of a synthetic resin (2), and bottom shell (3), It has at least one pair of welding support compared by extending between the insides of upper part shell and bottom shell, and has a charge of a filter material (5) which covers the fluid passage center tube which intervenes around a welding support between the above-mentioned shell which joins, and this center tube, and forms a bag filter. This VCF assembly is simultaneously welded by one oscillating welding operation. Moreover, the better flow of transmission fluid is offered by avoiding the flow resistance produced with the reinforcement support of the conventional technology.
