Bag 
            Filter Vessels 
            A wide range of pressure vessels and allied equipment manufactured 
            to high engineering standards. Vessels are constructed from polypropylene, 
            mild steel, Stainless steel (304 or 316) or other specialist metals. 
             
          Equipment 
            Connections can be NPT, BSP and ASA Screwed or flanged in the different 
            configurations to suit the customer's requirements. All bag filters 
            vessels are compatible with all standard snap ring filter bags as 
            well as our other custom designed bags. These can be supplied in single 
            or multiple bags in a vessel assembly. 
          All 
            filter vessels are supplied complete with a stainless steel retainer 
            basket and standard rubber O-ring. All other types of O-rigs can be 
            supplied at extra Cost. 
          Series 
            Filtration in which the first vessel feeds the second vessel and so 
            on. 
            The liquid is filtered more effectively when there are any of the 
            following conditions: 
            
          Unequal 
            Particle Size Distribution, in which First stage can handle larger 
            particles, subsequent stages can filter finer particles. 
            Redundancy for Greater Quality Control and Performance in which you 
            can acquire improved performance with two filters (same micron) back-to-back 
            for greater efficiency and capture rates. 
            Cost Reduction Using Disposable Filters where less expensive pre-filters 
            (disposable or reusable) can be used for the First stage, whereas 
            "Absolute Rated" media can be used in the subsequent stage 
            (s). 
            You can use parallel duplex or multiplex filter assemblies for uninterrupted 
            flow and where frequent bag change outs are required.
