|
| ||
| Filtration Grade (Micron Rating): | Filtration grade (micron rating, Beta ratio) describes the ability of a fluid filter to remove contaminants by particle size. Machinery manufacturers may accept the Beta ratio, but refrain from using this information to identify or specify their filters. Unlike fluid filters, air filters are not rated by micron size. | ||

Materials of Construction

| Back to Top
|
|
| ||
| Filter Media Material: | |||
| Your choices are... | |||
| Activated Carbon | Activated carbons are made of a variety of materials, the most common of which are bituminous coal and lignite. They have specific properties that are a function of the material source and the mode of activation. Property standards are also useful in specifying activated carbon for a specific application. Granular carbons from bituminous coal and lignite are used mainly in wastewater treatment applications. Granulated, activated carbon can also be produced by roasting organic material. | ||
| Activated Clay | Activated clay is used to remove dissolved contaminants such as acids, oxidation by-products, colors, and surfactants. | ||
| Diatomaceous Earth (DE) | Diatomaceous earth (DE) is a naturally-occurring mineral derived from the microscopic, fossilized remains of marine diatoms. DE has high absorption, low bulk density, and high brightness. | ||
| Cellulose | Cellulose is made from plant fibers. Because it is a natural material, its fibers are rough in texture and varied in both size and shape. These characteristics create a higher restriction to the flow of fluids compared to synthetic media. Cellulose types include cellulose acetate, nitrocellulose or cellulose nitrate, and regenerated cellulose. | ||
| 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. | ||
| Cotton | Cotton is a highly-efficient filtration media because its fibers are irregularly shaped and have good absorption properties. Cotton filters are often a good choice because they provide increased tenacity under wet conditions. | ||
| Glass Fiber | Glass fibers are completely-incombustible inorganic fibers. They have a high tensile strength in relation to their weight and dimensional stability. Glass fibers do not stretch or shrink. They do not absorb water and resist mildew, deterioration, and decay. | ||
| 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. | ||
| Metal / Porous Metal | Metal or porous metal filters have a large surface area to trap condensable particles and oil vapor. Products are often corrosion resistant. | ||
| Mineral / Sand | Sand filtration is often used to eliminate suspended solids from liquids. Though relatively inexpensive, the filtration media must be changed often. | ||
| 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. | ||
| Paper | Porous paper can be used specifically for filtering. | ||
| 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). | ||
| Polyester / Fiberglass | Polyester is a manufactured product whose fibers are long-chain, synthetic polymers which, by at least 85% per weight, are composed of an ester of a substituted aromatic carboxylic acid, including but not restricted to substituted terephthalic units. | ||
| 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-processable 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. | ||
