This construction ensures that nothing bypassesthe process media through holes in sewn fabric.Proprietary ConstructionHAYWARD’s proprietary construction processes producea reliable, durable filter bag. All seams are fully welded,producing strong, reliable joints with no by-pass or loosesewing thread. Seams are both strong and flexible, allowingthe filter bag to form to the restrainer basket. The seamedges are heat sealed, eliminating possible loose fibers.This results in a filter bag with durable performance for themost demanding applications.SENTINEL ® Seal RingAll HAYWARD SENTINEL filter bags utilize the patentedSENTINEL seal. Its all-plastic construction provides aflexible, chemically resistant seal which adapts to any filterhousing. This unique design employs a pressure activatedsealing lip which responds to increases in differentialpressure. As the pressure increases, the seal of thering improves, insuring by-pass free performance over allranges of pressure, temperature and micron rating. Theelevated bag handles make removal of the bag from thevessel quick and easy. When a SENTINEL filter bag isinstalled into a HAYWARD filter vessel, the ring snaps intoplace, holding its position until the vessel is closed.PRODUCTCODESPO: Polypropylene NeedlefeltPE: PolyesterNMO: Nylon, monofil meshPOBag MaterialBags/Box Box SizeS, M, L25 P 02 E30LMicron Rating µmP: PlainBag Cover LayerE: Polypropylene SENTINEL ® Ring, weldedH: Polyester SENTINEL ® Ring, weldedZ: Santoprene SENTINEL ® Ring, sewnBag Size Collar/Ring Type Options PackagingSENTINEL ® Range1 255 50 20010 100 1250Code Size01 ø 7 x 17 inches L02 ø 7 x 32 inches L03 ø 4 x 9 inches L04 ø 4 x 15 inches LWW42
