Flange for a device for separating an oil aerosol from air

An apparatus for separating an oil aerosol from air comprising:

• a base member;
• an annular coalescer mounted on said base member via a flange consisting of metal sheet coated with rubber;
• and
• a housing surrounding said coalescer, said housing being mounted on said base member,
• wherein said flange extends between said housing and said base member to form a seal therebetween, and
• wherein said base member includes a first passage and a second passage therethrough, an exterior of said coalescer element being in communication with one of said passages, an interior of said coalescer element being in communication with the other of said passages, wherein a portion of the metal sheet which is coated with rubber extends to an area of said base member between said first passage and said second passage to form a seal therebetween.

An apparatus for separating an oil aerosol from air, comprising:

• a base member including a passage for an air-oil mixture and a passage for clean air;
• at least two annular coalescer elements, each said coalescer element being mounted on said base member via a respective flange, an exterior of each said coalescer element being in communication with one of said passages, an interior of each said coalescer element being in communication with the other of said passages;
• and
• a respective housing surrounding each said coalescer element, said respective housing being mounted on said base member,
• wherein each said respective flange consists of a metal sheet with at least a portion of the metal sheet being coated with rubber, said portion of the metal sheet which is coated with rubber extending between said respective housing and said base member to form a seal therebetween.
