2 Dimensions are general, all information to be confirmed with design SELECTION CHART45 RAM liquid filtration PRODUCT | filter bag vessels are designed for industrial service. Single bag units are ideal for batch service or when flow interruption is possible. Four standard sized vessels handle various rates of flow and service. Industry standard filter bag sizes of LFB1, LFB2, P1S and P2S are used and also available from RAM liquid filtration . Consult the filter model table to determine applicable housing size based on flow rate. The RAM duplex model FI-400 is suitable for a maximum flow rate of 360 GPM, above this see multi-filter any of RAM s single bag unit designs, manifolds can be added to accommodate two or more housings. Manifolding of two or more units allows for continuous flow while one of the bag chambers is taken off line for filter change out. All vessels are equipped with quick opening covers to facilitate quick and seamless bag change out.

3 Housings come standard with #10 wire mesh basket to support the filter bag. Housings are designed to produce a low pressure drop and provide the greatest efficiency and life of filter bags. SPECIFICATIONS: Quick opening hinged cover with handle Carbon steel, 304L/316L stainless steel All closure hardware Vent and gauge connections Legs or mounting bracket EPDM or BUNA N sealsOPTIONS: Displacement float Alternate material of construction Magnetic post inserts Viton or teflon seals Polished finish for clean serviceFI SERIES SINGLE BAG FILTER HOUSINGS FI MULTI BAG FILTER HOUSINGSM ulti bag housings provide the optimal solution for high flow rates or heavier solid load. Each multi bag housing contains a series of #10 wire mesh baskets to support individual filter bags. The wire mesh basket offers tremendous integrity while providing the highest open area keeping pressure loss to a minimum. Typical applications include cooling water, plant effluents and many high volume liquid products.

4 Not limited with filter area the multi bag housing is ideal for both heavy solid load applications and higher viscosity liquids.

NOTE: (A) For flow rates higher than CHART - divide desired flow by flow given in CHART to obtain resultant DP. (B) For #2 size bags - multiply results by 2. (C) For LFB-1 size bags - divide results by 4. (D) For LFB-2 size bags - divide results by 2.
