How do you determine the replacement cycle of the filter element?

answer:

The filter element replacement cycle is determined by pressure loss. Normally, when the pressure loss exceeds 0.68kgf/cm2, the needle of the filter differential pressure gauge points to the red zone, or the filter needs to be replaced after 6000 to 8000 hours (1 year) of operation. The activated carbon filter should be replaced if odors are detected downstream. Why should the filter element be replaced regularly?

answer:

As the filter element continues to become fouled, the flow of gas through the system will decrease and the pressure drop will increase. At the same time, the consumption of energy and electricity also increases. The result is increased operating and production costs and an increased environmental impact.

What should be considered when installing filters? answer:

(a) Working pressure must not exceed the maximum pressure marked on the filter.

(b) Filters should normally be installed after the aftercooler and air receiver, as close as possible to the point of use and the point of coldest temperature.

(c) No filter shall be installed after the quick opening valve to prevent backflow or impact phenomena.

(d) Filters must be mounted vertically with enough space down to replace the filter element.

(e) Larger filters should be properly supported inline. What precautions should be taken when replacing the filter element?

answer:

(a) Isolate the filter, close the inlet valve or compressed air supply system, fully depressurize and close the outlet valve (or close the corresponding valve and fully depressurize the relief port of the filter). To unplug).

(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 must be firmly attached.
