One of the most important design considerations when purchasing a cone strainer is specifying the perforation or mesh size of the straining element.
In general, screen openings should be approximately one-half the diameter of the largest allowable particle. The largest allowable particle is defined as the size of particle that can pass through downstream equipment without causing damage.
A critical consideration when sizing a cone strainer is the amount of free open area. This is the ratio of the open area through the strainer screen to the cross sectional area of the pipe.
We can size a cone strainer to match your minimum Open Area Ratio requirement and provide a data sheet and submittal drawing for consideration.
Commonly requested ratios include: >100%, >150%, >200%, >250%, >300%
