Coalescing filter cartridges are especially designed for
moisture, oil & particulate removal. About 99-99 % of
oil & water aerosols are removed from air & gas streams.
The cartridge has stainless steel shell and support
components. The stainless steel outside wrapper supports
the filter media since the flow differential pressure
are from the inside to the outside. The cartridge is
made from HEPA filter media which in gas service will
remove better than 0.3 micron particles. HEPA filter
media is supported by SS wire mesh to take care of high
pressure differentials.
Principle:
Flow is from the inside to the outside of the
cartridges. Oil, water & other liquid aerosols pass
through the filter media where their reduced velocities
allow them to “wet” the filter fibers thus forming large
droplets. These cartridge droplets continue moving
through the filter media. The droplets collect on the
outer cartridge and drain, by gravity, to the bottom of
the filter cartridge housing where it s collected
through an extended sump outside.
Although the cartridges will remove particulate, it is
recommended that a particle filter be installed upstream
of the coalescing filter, operating in the standard
outside to inflow configuration .This will significantly
extend the life & improve the removal efficiency of the
moisture - oil removal coalescer filter cartridge. |
