How much debris

Debris

The size of a LPD Y Strainer screen is much larger than a conventional Y Strainer. The same amount of debris in each would actually block a much smaller percentage of the LPD Y strainer screen. To visualize the amount of debris in the strainer screen, we have chosen to use areas equivalent to the size of a dollar bill, 16.0254 square inches. The area we used for the conventional screen is the published area of a leading Y Strainer manufacturer.

   

To help visualize the amount of debris, we use a size equivalent to a US $1 bill: 16.0254 sq. in. (103.39 sq. cm.)
