# sintered element metal powder alloys are available is pressed in a die at sufficient pressure that the powder particlesadhere at their contact points. # strainer element the strainer is cup, Shaped and includes an inner cup, Shaped support structure having staggered perforations extending through the an outer, Surfaces thereof cup, Shaped strainer structure constructed made from woven wire is closely received over the support structure. # element nominal pore size the element nominal pore size is normally calculated from the pressure required to cause air tobubble from the largest pore in the filter element when submerged in a test liquid.
