GQ (C)/GQ series gas filters are the matching products of gas turbine flowmeter and gas waist wheel flowmeter produced by our company. When the gas quality is poor, it is used to filter the dust, droplets and impurities contained in the air flow in the pipeline to ensure the normal operation of the flowmeter. The filter is also suitable for various pressure regulating devices.
The filter core has large filtration area, low pressure loss, corrosion resistance and no two pollution.
The filter element can be cleaned many times and used repeatedly.
Compact structure, easy installation and simple maintenance.
The differential pressure gauge (GQC Series) can display the dirty degree of filter element.
DN250 and DN300 are designed and manufactured according to GB150-1998 "steel pressure vessel".
It is suitable for natural gas, artificial gas, liquefied petroleum gas, air and other media.

1: determines the discharge period according to the conditions of use so as to eliminate the accumulated water and impurities in time.
2: When the filter screen is blocked by dirt and the pressure loss increases obviously, it should be cleaned in time, and if there is damage, it should be replaced in time.
3: Use kerosene or other detergent, clean the dirt carefully with non-metallic brush, and know that the filter element is clean as before.
4: When cleaning or replacing the filter core, the inlet and outlet of the filter should be cut off first, and the gas in the filter should be replaced with nitrogen. The gas should be discharged into the safe area. After each cleaning, the leak should be re-detected. After confirming that there is no leak, the air in the filter should be replaced with nitrogen, and then the operation can continue.
5:GQ(C) series should close the inlet and outlet valves at both ends of the differential pressure gauge before ventilation, and then slowly open the two inlet and outlet valves at the same time when the pressure is stable to avoid excessive pressure on one side of the differential pressure gauge.
