Using a coalescing filter element installed in a housing the wet gas passes though element inside to outside. The fine fibres of the inner element capture the fine liquid aerosols and droplets and they run together along the fibres to form large drops within the depth of the element. These large drops are then forced to the outside of the filter element and then drain to the bowl of the housing by gravity. The filter element will slso remove particulates at the same efficiency.
Features:
·Extension current route to slow pressure drop
·High grade aluminium-silicon and carbon-steel cartridge
·Painted surface with epoxy resin for wear resistance and corrosion resistance
·Screw threads structure at inlet and outlet for easy installation with air flow indication on the cartridge
·Compact design for flexible troubleshooting
·Update pressure indicator to secure element replacement
·Level indicator to monitor critical level for downstream pollution prevention
·Reliable automatic drain.

Note：*filtration rating
Correctional parameter of operation pressure

Please make velocity of flow listed in above sheet multiply correctional parameter which corrwsponds to the minimum pressure of filter’s inlet when pressure is not 7 bar.And make sure not to choose filter according to dimensions of pipe connection but velocity of flow and operation pressure.
