Oil mist housings are available for applications requiring removal of mist from operations using oils or coolants. The housings are epoxy painted, seam welded and provided with a bottom pan to catch the oil or coolant as it collects and runs off the filters. Drain lines can be connected to the catch pan and piped to drums or containers. Metal mesh mist eliminator filters are used in the first stage followed by either bag or cartridge filters in the final stage. Leak tight doors prevent air and mist leakage.
