Welded Polyester Felt (PESP1PW) Filter Bag 7" x 16" Industrial Size #1 1 Micron, 25 Pack

Welded Industrial Filter Bags Use for Filtering Any Liquid Welded filter bags offer some advantages over sewn filter bags: No needle holes No Thread Contamination Precision bonded cutting of the fabric edges Maintains the same efficiency of the filter media 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. What is a Micron? 1 Micron = 1 x 10-6 meters = 0.001mm Some Common Particle Sizes: Beach Sand = 700 Micron, Fine Sand = 250 Micron, Portland Cement = 74 Micron, Silt = 44 Micron, Plant Pollen = 37 Micron, Red Blood Cell = 12 Micron, Cigarette Smoke = 2 Micron General Introduction to Liquid Filtration 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.
