The Y-Strainers consists of a housing with opposite arranged in and outlet connections at the same level. Between these connections is a basket strainer made of a perforated plate, optionally covered with a cloth consisting of various materials and mesh widths. The medium to be filtered will enter the filter from the inside to the outside. Hence, the contaminations will remain within the strainer insert. The Y-Strainer could be depressurizing through the venting or draining devices. After removing of the flap the complete basket strainer could be easily removed out of the filter housing. Now the strainer can be cleaned by blowing out or blasting using compressed air, steam, or water. If necessary, the strainer should be soaked and cleaned using a suitable agent. Possibly, an optimal cleaning will be obtained using ultrasonics. The housing could be manufactured by forged steel, cast iron or a weldment (pipes and flanges). Y-Strainer can be installed both in the horizontal and vertical positions without any effect on performance providing the screen is installed in the downward position to assist draining and cleaning operations.
