1 Cartridge Filter Housings Nowata A Series Customization May Change the Model Number Designation to B, D or F Series 1. Introduction All A series cartridge filter housings are designed for efficient liquid filtration and can be customized with a wide range of features and options. Flexibility in the exact design of your filter is an important advantage of our filter housings. We will help you design a filter to fit the exact configuration and needs of your operating environment. The housing's robust construction gives extended life in the toughest conditions. The epoxy coated AS Series option has been the industry standard for produced water and brine filtration for many years. These filter housings provide operators with highly efficient liquid filtration, matched to their specific operating requirements. Flow rates, operating pressures and temperatures, plus the fluid being filtered are all taken into consideration when selecting the right Nowata filter for the job. A series cartridge filter housings can be designed for many working pressures, flow rates, number of cartridges, mounting hardware, connection location, ASME code construction and more. These choices allow us to create a filtration system that is matched to your exact operating conditions. Features Sizes from to 1 cartridges to psi working pressure Aqueous flow rates to 6 gpm Bolted closure for safe, fast cartridge replacement Multiple O-ring closure seals available ASME code construction available Housing Material Choices Standard carbon steel construction Carbon steel with stainless steel trim & epoxy lining Stainless steel wetted construction

BLANK 3. Standard Construction Notes Standard A Series Construction A series models are designed for applications involving fresh water and non-corrosive fluids. They are constructed of all welded carbon steel with internal cartridge supports and retainers of Brass. Larger models come standard with closure lifting davits for easy cartridge removal. 3" or smaller inlet and outlet connections are FNPT internal pipe thread. The " and larger sizes are provided with ANSI flanges. Internal pipe threaded vessel drain, backwash drain and vent are standard, with the size depending on vessel diameter. U Series Construction Feature The U series feature is designed for applications requiring the increased corrosion resistance and fluid compatibility of stainless steel. All wetted surfaces, including the cartridge supports and the retainers, are 316 stainless steel. The top closure is constructed of high-strength carbon steel, with a stainless steel liner plate. S Construction Feature The S feature provides epoxy lined carbon steel construction, with 316 stainless steel in the uncoated area of the closure o-ring seal. Internal pipe thread, vent and drain connections are also made of 316 stainless steel. Brass internal cartridge fittings are furnished as standard, other materials are available. Although exposed areas are made of 316 stainless steel, all wetted carbon steel surfaces are coated with epoxy. Care should be taken to use the S feature housings with fluids that do not vigorously attack plain steel. Standard Construction for Glycol Filtration A series models are especially suited for removing solids from triethylene glycol in natural gas dehydrators. Since Brass cannot be used with glycol, plated carbon steel internals are required. Solids in the glycol stream can damage pumps and plug spray nozzles. Most applications require filtration in the 2 to 0 micron range, to provide the protection needed. Working Pressure Ranges A series housings are available in the following maximum allowable non-shock working pressure ratings: psi, psi, psi, and psi. Cartridge Filter Housings, Nowata A Series 3

4 . Optional Construction Notes Seal Material The standard Buna o-ring operates at up to 20 F. Viton seals are available for up to 0 F service. Other o-ring materials, such at Teflon encapsulated silicone, and ethylene propylene are also available. Connections Customized inlet and outlet connection sizes and locations are available on all filter housings. All units are available with optional external pipe thread connections or ANSI flanges. Internal pipe threaded drains and vent are provided as standard. Connections are also available in flanged or external pipe thread type, or in non-standard sizes. Special purpose connections, such as relief valve fittings and pressure taps, are also available. Non-standard connections location, unusual mounting heights or dimensions are also available. Internal Materials Standard brass and optional plated carbon steel internals are stocked at the factory. 316 stainless steel is standard for the U series and optional on the A series.. Typical Applications MPTY Waterflood Filtration Our filters are used to clean the water being injected into wells surrounding a producing oil well. This water must be filtered in order to prevent plugging of the injection formation, which also keeps the fluid environmentally friendly. Filters For Disposal Produced water from an oil field, to be re-injected into the ground or reintroduced into the ecosystem, must first be filtered to remove contaminants, and thereby not damage the environment. A series cartridge filter housings are especially suited for the job, providing excellent, cost effective filtration. 6. Optional Corrision Resistant Epoxy Coating MPTY Longer Life, Lower Cost The cost of filtering corrosive fluids can be reduced with the AS option for the A series cartridge filter housings. Filtering saltwater and other corrosive fluids has been a problem for operators and engineers. The only choices were between carbon steel vessels with limited life or with expensive all stainless filters. The AS option for the A series filter housing designates construction materials for use in filtering corrosive fluids by utilizing a combination of stainless trim and epoxy lined carbon steel. This design offers the benefit of longer vessel life at a much lower cost than all stainless steel construction. Horizontal Housings Our rigid cartridge support and seal system is ideally suited for the horizontal configuration of the A series housings. This is especially important when overhead clearance, or other unique operating considerations preclude the usual vertical installation of the housings. Extra Length Housings and Cartridges When extra dirt holding capacity is needed, an extra length housing can be built to hold our 0" length cartridges. This offers the advantage of a 33% increase in cartridge life, for little extra cost. ASME Code Construction A series filters are designed in accordance with the Pressure Vessel Code of the American Society of Mechanical Engineers. When required, each unit can be stamped with the appropriate ASME code denoting fabrication and testing performed by specific procedures. Accessories Several items are available to monitor or control filter operation. Ask us about accessory features for your filtration system. Glycol & Amine Filtration The removal of solid particles from glycol or amine in a gas treatment system is very important for the performance of the equipment. Our filters and cartridges are an excellent choice for this type of filtration application. General Industrial Filtration MAHLE filters, with their wide range of capabilities in terms of micron ratings, flow rates and working pressures, are excellent for use in many types of industrial filtration. Contact us to customize a filter system to your application. Corrosion Resistand Epoxy Lining The A series housing becomes an AS series when the Epoxy Coating is used. Each of the critical areas in the AS filter housings, including the cartridge post receptacles, dirty chamber drain, vent and clean chamber drains, are made of stainless steel. The o-ring seal area is stainless, as well as the wetted area of the closure. The filter is then completely lined with -20 mils of heat cured epoxy, which results in all wetted areas being either epoxy lined or stainless steel. The following diagram shows the wetted areas of the housing in either stainless steel or with the epoxy coating. Cartridge Filter Housings, Nowata A Series
