Using a pressure regulator? You need a pressure regulator filter. Classic Filters’ range of filter housings will give you all the protection you need.
Most pressure regulators have a small diameter flat filter disc installed into the inlet port. Usually of a grade of 20 or 25 micron, these discs have a very small surface area and tend to block quickly if there are solid particulates present. The location of the inlet filter disc makes servicing a time-consuming chore and the compression fitting needs to be removed from the inlet port to gain access to the filter disc.
High Flow Rates & Longer Service Life
If the inlet filter disc installed in the pressure regulator is removed then the flow rate will be increased – in which case a filter housing is essential to give protection to the regulator.
