The Model MACA is a mechanical air cleaner incorporating special pleated filter media designed to remove dirt, dust, pollen and other microscopic particles from the air passing through it. The pleats provide an exceptionally large filtering face area in a very compact space which allows maximum dirt holding capacities with minimum air flow resistance. (See Table 1.)
