The Model 91 Tee Strainer offers several advantages over other strainer designs. The strainer is very compact, important in applications where space is restricted. Unlike most other strainers the Model 91 can be used in both vertical or horizontal installations and the strainer screen can be cleaned without draining the strainer housing.

These strainers also feature a convoluted strainer screen and an unrestricted flow path that results in a very low pressure drop compared to other strainer types. This makes the strainers ideal for applications such as condensate and boiler feed pump suction where the process water has low solids loading and the pressure drop is critical.
