Properly Calculating Open Area


Some synthetic screen media manufacturers claim their panels have “the highest open area in the industry”. However, their open area calculation is often based incorrectly on just the panel area containing holes, rather than the entire surface area. When calculating open area using the ENTIRE surface area it becomes clear that Polydeck’s MAXI screen panels have more open area than competitive designs with the same overall surface area.


OPEN AREA % = CORRECT


TOTAL OPEN AREA OF HOLES TOTAL PANEL SURFACE AREA


INCORRECT


Reference 21


When comparing panels with the same size opening, counting the number of holes is also an effective method of comparison.
