Application of Bag Filter Vessels
FiltEdge’s bag filter is widely used in water treatment, chemical, beverage, pharmaceutical, petroleum, automotive, laboratory, etc., guarding your productivity with professionalism.
In industrial circulating water, reverse osmosis pre-filtration and other applications. Impurities in the water lead to corrosion and scaling of pipelines and damage to expensive downstream facilities.FiltEdge’s Bag Filter Vessel utilizes SUS304/316L Stainless Steel Housing with filtration accuracy covering 1-100μm to achieve extremely low operating differential pressures. The use of this filter retains more than 95% of particulate contaminants, reducing the frequency of filter element replacement in back-end precision equipment by approximately 50-80%, dramatically reducing your operating costs.
In the production line of all kinds of synthetic resins, paints and coatings, daily detergents, fine chemicals and so on. Incomplete filtration of slurry will result in particles, uneven color, and even leakage of containers due to corrosive substances.FiltEdge adopts SS316 or PVDF material and unique safety lock pressure relief design of the filter, and the surface is then acid washed and passivated to ensure chemical compatibility. It increases your product qualification rate by about 10%-15% and reduces the frequency of downtime and raw material waste.
Used in the production of beer, beverages and dairy products as ingredient water, fine particles in the water can change the taste and color of the beverage, and even lead to food safety accidents. FiltEdge uses FDA food-grade certified SUS316 Bag Filter Vessel with internal electrolytic polishing to Ra <0.4μm, to achieve a hygienic dead space. Achieve sanitation without dead space. Eliminating the buildup of scale and bacteria inside your filters reduces your cleaning frequency by approximately 30% and ensures that your production water meets sanitary standards.
In the electrophoresis cycle, topcoat spraying, and pre-treatment stages of automotive vehicle/component production, particles in the paint can cause Dirt on the body finish. FiltEdge utilizes the Zero-Bypass sealing construction and polished interior of the Bag Filter Housing Vessel, as well as a multi-pocket design to ensure that pressure is maintained smoothly during the painting process. The FiltEdge utilizes a Zero-Bypass seal and Bag Filter Housing Vessel with polished interior walls, as well as a multi-pocket design that ensures smooth pressure during the painting process. This solution reduces the rate of paint impurity defects by approximately 25-40%. It protects your film formation, reduces paint line downtime for cleaning, and saves you hundreds of thousands of dollars in rework costs.
