发明名称 Molded panel filter
摘要 A fluid filter element comprises a first filtering medium and a second filtering medium. The first filtering medium includes a nonwoven batt having a marginal edge portion circumscribing the main body portion of the batt in which the fibers are stiffened to provide a support and sealing structure. The second filtering medium includes a nonwoven batt which has been welded into a convoluted drape and which has a circumferential edge portion which provides a supported and sealing structure. The circumferential edge portion is sealed to the marginal edge portion when the fluid filter element is assembled.
