Welded Polyester Felt (PESP4PW) Filter Bag Size#4, 4" x 14", 25 Micron, 50 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.
