SWITCHABLE FILTER (L TYPE)
COS-L MODEL
1MPa(10kgf/cm2)
1.This is a steel-structure, switchable duplex housing.
Maximum operating pressure……1MPa(10kgf/F)
2.Easy handle operation allows changing and cleaning of
element without interrupting of operation.
3.Element material - nominal rated medium and strainer …
Type A. Notch wire … Type B.
Flow direction is different between type A and B.
4.Standard flange is JIS 10K-FF.
5.Due to the cock structure, internal leak occurs in the
stand-by period. (Leakage is adjusted within the specified
volume as shown in the table on the next page).
