The y-type strainer is the most common and economical type of strainer for permanent applications, suitable for liquid, steam and gas mediums. Due to quick cleaning y-type strainers are used in manifold manners. Other advantages of the y-type strainers are the large filtration area, which provides a high filtration capacity, a low pressure loss and therefore longer operation time.
The y-strainers consists of a housing with opposite arranged in- and outlet flanges 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 cover the complete basket strainer could be easily removed off 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 ultrasonic.
y-strainer can be installed both in the horizontal and vertical positions without any effect on the performance.
