The TRION MP1500-M units are designed primarily for the filtration of mists from ventilation air as found in the metal removing and forming industries. The mists may be created from either oil-based or water-based coolants like those used in cutting and grinding operations. The units, arranged vertical for upward airflow, are in the collecting efficiency range of 95% and consist of an air inlet chamber, a series of three or four filtration stages and a blower. There are various options available for each stage of filtration and the options are dependent upon what is specified for the particular application.
