New Edwards Vacuum EMF20 Oil Mist Exhaust Filter, A46229000
The Edwards Vacuum EMF Oil Mist Filters are used to separate and trap oil mist and odours discharged with the exhaust from oil sealed rotary vacuum pumps. All of the EMF Oil Mist Filters are similar in construction.
The Oil Mist Filters have two-part injection moulded plastic bodies which contain a fiber composite oil mist filter and an activated carbon odor filter.
Exhaust gases from the pump travel upwards to the center of the Oil Mist Filter and through the filter element to the outside. Oil droplets that are trapped by the fiber composite element travel down the filter and collect in a reservoir in the base of the Oil Mist Filter.
The oil-free exhaust fumes then pass through the activated carbon filter element to remove any residual odors.
The filter element has a pressure relief valve. If the element becomes blocked, the pressure relief valve allows exhaust gas to bypass the element and prevents pressure build-up in the pump. The pressure relief valve does not allow gas to escape from the exhaust system. A high exhaust pressure, caused by a blockage elsewhere in the exhaust system, will not be relieved by the pressure relief valve.
The amount of oil that has accumulated in the filter is visible through the sight panel on the lower part of the filter body. When the oil level reaches the maximum oil level, you should remove the drain plug to drain the oil from the filter.
The EMF Oil Mist Filters are resistant to many chemicals and solvents and are unaffected by alkalis, detergents and salt solutions. The EMF Oil Mist Filters are also suitable for use with chemicals that form azide compounds.
The EMF series filters are manufactured with NW flanges sized to suit the dimensions of the filter and the pump that it is designed to fit.
EMF Mist Element and EMF Odor Element included.
