GF Series Filter bags
Introduction
Filter bags is the core filter element of bag filtration system. It determines filtration performance and final product quality directly.The filter bag is composed of a ring mouth and a bag pocket,Polypropylene rings or stainless steel rings are placed at the neckline of the support basket, and the bag pocket is attached to the inner wall side of the support basket.
impurity particles are caught in the bag pocket to intercept the internal.
Our international general filter bags are divided into conventional filter bags and high-efficiency filter bags. They can be installed on any international standard filter, such as Eaton, FSI, Rosedale, etc.
General Conventional Filter Bag
■ PP Polypropylene Filter Bags: pure polypropylene deep filter media, endure acid and alkali, the maximum temperature of 95 ℃, the recommended temperature is below 90 ℃, the polypropylene fiber filament, nominal filtration fineness: 0.5 ~ 300μm
■ PE Polyester Filter Bags:Polyester deep filter media, endure alkali and solvent, he maximum temperature of 150 ℃, nominal filtration fineness: 1 ~ 300μm
■ NO Nylon Filter Bags : Made of nylon monofilament weaving, the surface filtration media,endure acid and solvent, the maximum temperature of 160 ℃, nominal filtration fineness: 25 ~ 300μm,
High Efficiency Filter Bags
High Efficiency Filter Bags are available rated at 1-25 micron, and perform to efficiencies >95%.The filter bag consists of up to 4 layers of melt blown polypropylene media, including an outer cover to prevent fibre migration into the filtrate as well as providing added support to the filtration media. The high density of small diameter fibres compared to that of a standard needlefelt enhances particle retention, leading to superior, highly efficient filtration.
