YLG Series Gas Filter
Product Application
YLG series gas filters are mainly used for purification and filtration of natural gas, coal gas, liquefied petroleum gas and other non-corrosive gas media.
Product Features
Large filtration area, low pressure drop, long service life, high efficiency, and convenient installation, operation and maintenance. It is mainly available in coaxial flanged and angle-type flanged configurations.
This series filter can be equipped with a differential pressure gauge upon request to indicate clogging of the filter element for users to judge cleaning timing. Filter element materials include stainless steel, paper, nylon mesh, etc., with filtration precision ranging from 5 to 50 μm.
