Baida First granular desicrant style filter-driers
are designed for new installations, particularly
air conditioning systems. These dries have excellent
filtering ability and moisture removal capabilities.
The Sight Glass changes color depending on
the moisture content in the system. Color coding appears
green when dry, yellow when moisture is present. When
used as a sight glass in the liquid line, the best position
for the Sight Glass is after the filter drier and ahead
of the expansion valve. Made of forged brass.
