ABSTRACT:
The invention relates to a filter assembly for capturing particles in electric motor exhaust streams. That assembly comprises a filter of extended surface area, including filter material and a frame substantially wrapped by the filter material, and a securing means, preferably a C-shaped channel, for receiving the filter frame. In operation, the filter is slid into the channel and is held securely by the channel so that a positive seal is formed between the channel and the filter as an exhaust stream is passed through the filter.
