Device, method, and system to separate liquid and particulate matter from the airstream of a centrifugal fan

A system for separating contaminants from an airstream, the system comprising:

• two parallel flanges configured to be secured to a centrifugal fan housing;
• an outer flange connecting the two parallel flanges;
• a contaminant containment vessel mounted to the outer flange;
• and
• a diverter spanning the parallel flanges, such that the diverter is configured to separate a portion of an airstream flowing between the parallel flanges from a remainder of the airstream and accelerate the portion of the airstream towards the containment vessel.

A method of separating contaminants from an air stream, the method comprising the steps of:

• cutting a hole in a centrifugal fan housing, the housing having two sides and an outer wall connecting the sides, the hole spanning the outer wall and through both sides;
• mounting a housing adapter to the housing, the adapter including—a contaminant containment vessel exterior to the housing;
• and
• a diverter spanning the sides, such that the diverter is configured to separate a portion of an airstream flowing between the sides from a remainder of the airstream, accelerate the portion of the airstream towards the containment vessel, and thereafter guide the portion of the airstream towards the remainder of the airstream.
