Description
Disc cleaned filter type DCF-3000 filter consists of a cylindrical 316
stainless steel filter screen sealed within a 316 stainless steel filter
vessel. Unfiltered process fluid under pressure enters the filter vessel
through the upper port. The process fluid enters the inside of the filter
screen from above and the filtrate flows through the screen, exiting
the filter vessel through the lower port. Contaminants are trapped on
the inside of the screen. The contaminants are periodically scraped
from the surface of the screen by two cleaning discs assemblies
which travels across the surface of the screen. These contaminants
are deposited in a collection chamber at the bottom of the filter vessel
where they are periodically purged out of the bottom port of the filter
vessel.
WARNING: This filter is a pressure vessel designed to
operate under specific pressure, temperature, and
other engineering parameters. There is a risk of
explosion, process fluid leakage or electrical shock if
the requirements set forth in this Manual are not
followed either during installation, operation, inspection or servicing of
this equipment. Equipment should be shut down and isolated from
energy sources and other equipment before any inspection or servicing
to prevent risk of shock or process fluid leakage. Appropriate PPE
required. FAILURE TO FOLLOW THIS WARNING MAY LEAD TO
DEATH, SEVERE INJURY OR PROPERTY DAMAGE.
