Description
The EMF Oil Mist Filters (shown in
Figure 1
) 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 fibre composite oil mist filter and
an activated carbon odour filter.
Exhaust gases from the pump travel upwards to the centre of the Oil Mist Filter and through the filter element to the
outside. Oil droplets that are trapped by the fibre composite element travel down the filter and collect in a reservoir
in the base of the Oil Mist Filter.
WARNING
Warnings are given where failure to observe the instruction could result in injury or death to
people.
