Szu-a Squ-a Swu-a Sxu-a Duplex Return Line Filter Series

Short Description:

The SZU-ASQU-ASXU・A、SWU-A Duplex return line filter series are composed of two single bowl filters and one 2-position 6-way directional valve. It is simple in structure and easy to use, There is by-pass valve and contamination indicator in it, for protecting the hydraulic system safety.
The feature of this filter allows continues operation during replacing the element which is clogged by contaminant. By opening the balance valve and turning the direction valve, the other filter will be working, the clogged element should be changed at that time.
This series filter is widely used in the hydraulic systems of heavy-duty mining and metallurgical machines.
