These series filters are of return line type. The filters element of QU-A,ZU-A WU-A series
is made of glass fibre, paper & wire mesh. They have the same working pressure but
different filtration rating. Differential pressure indicator will act when the pressure drop
across filter element reaches 0.35MPa.
