Dry gas filter is equipment used in the gas pressure reduction and metering plants, which protect the pressure regulators, the valves, the positive displacement meters etc. from the solid particles present in the gas, if any. The filters construction is stout and they may be easily installed and maintained. The filtering element is able to filter the solid particles up to 5µ.
