Configuration



	Your choices are...
	RO Membrane / Media		Bulk filter media is porous material with a defined pore structure. It is used as a particle collector. For Reverse Osmosis applications, bulk media is typically supplied in sheet form.
	Reverse Osmosis Element		RO elements are porous devices that perform the actual process of filtration. RO elements typically consist of filter "leafs" that are wound around a core that serves as an outlet for the purified filtrate. The raw fluid is recirculated across the wound filter leafs under high pressure such that only water (not ionic species or particles) may pass to the outlet core.
	Housing Only		Housing-only products are porous enclosures that direct the flow of fluid through the filter element.
	Housing and Filter Assembly		Housing and filter assemblies have built-in casings or enclosures that cover and/or protect the filter assembly.
	System		A filtration system will include the filter, filter housing, and the associated piping and pumps to move the fluid through the filter.

Performance Specifications

	Maximum Pressure		This is the maximum pressure at which the filter is designed to operate.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

Materials


	Filter Medium Material:
	Your choices are...
	Polypropylene (PP)		Polypropylene (PP) is a thermoplastic material which exhibits excellent cold flow, bi-axial strength, and yield elongation properties. PP is similar to PVC, but can be used in exposed applications because it resists UV, weathering, and ozone.
	PTFE / Teflon®		PTFE is an insoluble compound that exhibits a high degree of chemical resistance and a low coefficient of friction. It is sometimes marketed in proprietary classes of materials, such as Teflon^® (DuPont Dow Elastomers).
	Polyvinylidene Fluoride (PVDF)		Polyvinylidene fluoride (PVDF) is a melt-process fluoropolymer that provides better strength and lower creep than other fluoropolymers. PVDF has good wear resistance and excellent chemical resistance, but does not perform well at elevated temperatures. Common brand names include Kynar^® (Elf AtoChem).
	Polyvinylidene Chloride (PVDC)		Polyvinylidene chloride (PVDC) can be made directly from ethylene and chlorine or by the further chlorination of vinyl chloride with the subsequent removal of hydrogen chloride by alkali treatment. Vinylidene chloride is polymerized in suspension or emulsion processes, using free-radical initiators. Because of its low permeability to water vapor and gases, PVDC is ideal for food packaging. Copolymers of vinylidene chloride and other monomers are also marketed.
	Polysulfone (PSU)		Polysulfone (PSU) is a thermoplastic polycondensate used in electric connectors. It has high strength, good toughness, good dielectric strength, and dimensional stability. PSU is sold under the trade name Ultrason^® (BASF Aktiengesellschaft).
	Synthetic Fiber		The filter medium material is synthetic fiber.
	Other		Other unlisted or proprietary materials.
	Polyethersulfone (PES)		Polyethersulfones (PES) are high-performance polymers that are similar to polycarbonates, but much more heat-resistant. Because PES resists water and steam, it is used to make products that must be sterilized between uses (e.g., cookware, medical instruments).
	Nylon		Nylon is a commonly-used, general-purpose material that comprises several grades of polyamides. Nylon is tough, resistant, and has good pressure ratings. Nylon membranes are compatible with most solvents, both organic and aqueous. Use with strong acids, 70% ethanol, methylene chloride, or dimethylformamide (DMF) is not recommended.
	Ion Exchange Resin		Ion exchange is a process that involves two similar applications of one technology. The first application is water softening, a process that removes ions from water and replaces them with sodium ions and chloride ions. The second application is deionization, a process that removes ions from water and replaces them with H⁺ and OH^- ions which can combine to form water. Ion exchange filters are used in residential applications to reduce hardness or improve the taste of water. They are also used to reduce deposits and scale from water with a high level of hardness. Deionization is often used when extremely pure water is required.
	Ceramic		Ceramic materials are made of nonmetallic minerals (such as clay) that have been permanently hardened by firing at high temperatures. Most ceramics resist both heat and chemicals.

	Housing Material:
	Your choices are...
	Aluminum		Aluminum is a bluish, silver-white, malleable, ductile, light, trivalent, metallic element that has good electrical and thermal conductivity, high reflectivity, and resistance to oxidation.
	Plastic		Plastic is a generic name for certain synthetic or semi-synthetic materials that can be molded or extruded into objects, films, or filaments.
	Steel		Steel is a commercial iron that contains carbon in any amount up to about 1.7 percent as an essential alloying constituent. It is malleable under suitable conditions, and is distinguished from cast iron by its malleability and lower carbon content.
	Steel - Stainless		Stainless steel is chemical and corrosion resistant and can have relatively high pressure ratings.
	Teflon® Coated		Teflon^® refers to a class of fluoropolymer resins used for a wide variety of commercial applications. They are highly-resistant to temperature, chemical reaction, corrosion, and stress-cracking. Teflon is a registered trademark of DuPont Dow Elastomers.
	Other		Other unlisted or specialized housing materials.

	Reusable / Cleanable		The filter element can be cleaned and reused.
	FDA Compliant		The filter meets requirements from the U.S. Food and Drug Administration (FDA).
	Integral Bypass		If the filter element becomes clogged, a bypass relief valve allows fluid to bypass the filter element and pass directly through the outlet port.
	High Delta P Indication		The pressure across the filter changes as the element becomes dirty. High delta P indication provides local indication that the element needs to be replaced.
