How to use the purification precision filter correctly

How to determine the replacement cycle of the filter element?

Answer: The replacement cycle of the filter element is determined by its pressure drop. Generally speaking, if the pressure drop exceeds 0.68kgf/cm2, the pointer of the filter differential pressure gauge points to the red area, or it needs to be replaced after 6000-8000 hours of work (one year). . Activated carbon filters are replaced when odors are detected downstream.

Why should the filter element be replaced regularly?

Answer: After the filter element is continuously polluted, the flow rate of gas in the system will become smaller and the pressure drop will become higher. At the same time, the consumption of energy and electricity will also increase. As a result, the cost of operation and production will increase, and the burden on the environment will be increased.

What aspects should be paid attention to in filter installation?

Answer: (a) The working pressure cannot exceed the maximum pressure marked on the filter.

(b) The filter should generally be installed after the aftercooler and the air storage tank, as close to the use point and the lowest temperature point as possible.

(c) The filter should not be installed after the quick opening valve, and prevent backflow and shock phenomenon.

(d) The filter should be installed vertically with enough space below to replace the filter element.

(e) Larger filters should be properly supported in the line.

What are the precautions for replacing the filter element?

Answer: (a) Isolate the filter, close the inlet valve or the compressed air supply system, and then close the outlet valve after completely releasing the pressure (or completely relieve the pressure through the drain hole of the filter after closing the relevant valve).

(b) Unscrew the housing and remove the old filter element.

(c) Clean the filter housing.

(d) Replace with a new filter element (do not omit the sealing ring, the filter element should be tightly installed.
