Particle Filter Element Element for the removal of solid contaminants in gases as a prefilter or post filter. Donaldson® Ultrapoly™ PE elements contain highly porous sinter polyethylene filter media. Even the finest dust particles and other contaminants in compressed air and gases are being removed effectively on the surface and in the depth of the filter medium. By utilizing various filtration mechanisms such as direct impaction and mechanical sieving, particles are retained 100% in gases related to the element pore size. Particle Filter Element The Donaldson Ultrapoly PE filter element is ideal in the following industries and applications: • General machine fabrication

Retention Rate Maximum Differential Initial Differential Pressure 100% in gases; defined rate of particles larger than the pore size Filter Media Pure high molecular polyethylene Epoxy resin Perbunan®*: silicone free and free of parting compound (standard) Pressure Drop Calculations Performance of PE elements — compressed air These curves define the flow of a 1030 filter element at standard conditions (14.7 psia; 68°F; R.H.= 70%) The performance curve is based on 1030 element, or one ten inch equivalent (TIE), and the correction factor for filter surface Cf for a Example 1: Low Flow Single Element...
