Answer: (1) The working pressure cannot exceed the maximum pressure indicated on the filter.
(2) The filter should generally be installed after the aftercooler and air tank, as close to the use point and the lowest temperature point as possible.
(3) The filter should not be installed after the quick opening valve, and backflow and impact should be prevented.
(4) The filter should be installed vertically, leaving enough space below to replace the filter element.
(5) Larger filters should be properly supported in the pipeline.
