ABSTRACT:
A filter for use inside tapered hot air nozzles positioned at spaced intervals along a feed line in a paint drying oven has an elongate cylindrical conduit formed of perforated stainless steel wrapped by stainless steel wire cloth having an absolute particle rating size of 80 microns. An open end of the conduit is connected to the nozzle port and a capped end extends into the nozzle feed line. A stainless steel adapter has a collar engaging the outer or inner surface of the nozzle adjacent the port and an integrally formed flange extending radially outwardly from the collar. A stainless steel retainer has a collar spot welded to the filter conduit adjacent the open end and an integrally formed flange extending radially outwardly from the collar and connected to the adapter flange by screws. A gasket is positioned between the flanges of the adapter and the retainer. Openings in the retainer flange have circular portions and slot portions extending in a uniform circumferential direction with respect to the flange to permit selective connecting and disconnecting of the adapter and retainer by relative rotation. An alternative filter has a galvanized wire mesh screen surrounding the wire cloth. The screen has longitudinal extensions which extend beyond the ends of the cloth and are rolled in against the conduit and welded thereto. An alternative retainer has a collar spot welded to the outer surface of a longitudinal extension of the conduit extending beyond the nozzle port.
