The MF 100 Oil Mist Filter removes oil mist (vapor) from the process gases exhausted from the outlet of an oil sealed pump. The filters remove both odor and oil vapor and so prevent it from reaching the atmosphere and the workplace. This filter is very efficient at 99.85% DOP test (pre-wetted filter; 99.5% with dry element). The oil level sight-glass provides easy monitoring of mist filter status. The MF100 mist filter is suitable for pumps from E2M28 to E2M80.
