GAS FILTERS Gas filters are used to separate dust and other particles such as oils, waxes, tar etc which are all heavy ends in Low and High pressure service lines. These are used to protect the system and the other safety equipment provided on the pipeline. These Gas Filters have negligible pressure loss across their end connections. LOW PRESSURE L.P. GAS REGULATOR WITH UNDER PRESSURE SHUT-OFF (U.P.S.O.) VALVE These Pressure Regulators are suitable for domestic L P. Gas / Natural Gas installations. They are fitted with an Under Pressure Shut-Off (U.S.P.O.) valve and a pressure relief valve, in the event of an excessive flow of gas, or a drop in it's pressure at the outlet of the regulator, the Under Pressure Shut-Off (U.P.S.O.) valve safely closes the outlet gas supply. When the under pressure condition has been corrected or repaired, the Under Pressure Shut-Off (U.P.S.O.) valve can be reset by pushing the button on the regulator.

As the filter is used and its element gets contaminated with heavy ends, the outlet pressure starts dropping with respect to its inlet pressure. This can be visually read from the two pressure gauges provided on the filter. The element requires changing when there is a drop of 50% or more between its inlet and outlet readings. The element can be inspected, and replaced without any disconnection from the pipeline.
