Therefore, filtering of abrasive matter required pre-treatment stages such as pre-filtration, centrifuging, or sedimentation in order to protect the membrane.
Describes some problems that have influence on the life time of air-conditioner such as correct use of pad, disposal of circulating water, pre-filtration of air and so on.
The major role of pre-filtration is to capture a portion of the oversized particles and protect the final filtration from premature plugging in order to deliver maximum filter service life.
