The proportion of total screen area that is open space. Expressed as a percentage.
The ratio of useable openings (apertures), to the total area of a module expressed as a percentage. Many systems require clamping devices which cover the edges and/or a portion of the apertures on each module. With reference to these systems the published open area is often misleading, as the loss of open area utilized for fastening is not taken into account. Flowmax systems do not require external clamping methods such as locking pins or clamps. Published open areas reflect the actual effective screening area.
The ratio of open space area between the wires, to the total area of a given section of wire cloth, expressed as a percentage.
The proportion of open space to the total area of a wire screen, expressed as a percentage.
