Duda Energy Welded Polyester Filter Bag (PESP4PW) Filter Bag Size#4, 4" x 14", 25 Micron, 2 Pack

Our welded filter bags have a durable plastic flange with handles for easy removal from a filter bag housing. The welded seams completely eliminate the possibility of unfiltered liquid bypass occurring due to needle holes. The result is a tighter seam with higher filtering efficiencies and improved finished product yields. The fused edges of the welded bag also provide a fiber-free finish which essentially eliminates any fiber migration from the bag to the working fluid. There is no possibility of silicone contamination since there are no threads.

• All filtration and screening involves limiting the passage of various sized solids by means of a barrier or fabric or media.
• This is done in two ways, by depth filtration using graded density material called felt or by surface filtration using filament woven material called mesh.
• Woven bags in turn have two basic varieties: multi-filament and monofilament.
• In any application, variables such as flow volume, solids loading, shape and density of contaminants and other factors make this an inexact science. A general description of separation methods of media is helpful.
