Mist filters capture oil mist from the outlet of pumps, which would otherwise be ejected into the atmosphere. The EMF20 mist filter is suitable for use with RV12 and E2M18 pumps. It can be used with an E2M28 on low pressure applications. They are very efficient at 99.999% DOP test and are also azide proof. The white bottom half of the body is semi-transparent, allowing the oil level to be monitored. The EMF filters have a unique odor element which neutralizes the smell of oil mist.
