VMF..M with test points
There is a retaining frame with an integrated strainer and filter
pad in the housing of the VMF. The filter pad is supported by
the strainer. The filter pad and the strainer rid the gas of coarse
as well as fine impurities.
In order to replace the filter pad, the two retaining screws are
undone and the base plate removed. The retaining frame with
the filter pad is pulled out. The retaining frame is opened and
the filter pad can be taken out.
The VMF is delivered with two test points for pressure measure-
ment as standard. The VMF can also optionally be delivered
with two 1/8“ screw plugs.
