Filter Construction

|
| ||
| Your choices are... | |||
| Housing and Filter Assembly | Housing and filter assemblies have built-in casings or enclosures that cover and/or protect the filter assembly. | ||
| Filter Element / Cartridge | Filter elements or cartridges are porous devices that perform the actual process of filtration. A filter element uses pleated or mesh construction and can be disposable (one-time use) or reusable. | ||

| |||
| Assembly / Element Type | |||
| Your choices are... | |||
| Cartridge | The filter element is disposable. | ||
| Bag | Bag filter elements are a lower cost alternative to cartridge-style filters. They are used to filter sand, rust, and pipe-scale from plant process waters; metal shavings and wear particles from recycled cutting, quenching, flushing and hydraulic oils and coolants; and to filter contaminants that can plug nozzles in spray systems. | ||
| Wire Mesh / Screen | Wire mesh (woven screen, wire cloth) is a metallic filter medium that is formed by weaving fine wires into a cloth with a controlled pore size. | ||

| |||
| Configuration | |||
| Your choices are... | |||
| In-line | In-line products are filter assemblies in which the inlet, outlet, and filter element axes are in a straight line. | ||
| Return-line (closed loop) | A return filter catches all debris generated by the system’s components and is designed to be the last component that fluid passes before returning to the system reservoir. The location of a return filter allows for much lower pressure ratings and helps reduce costs. | ||
| Off-line (Recirculating) | Off-line or recirculating filters are completely independent of a machine's main hydraulic system. This filter configuration is sometimes called kidney loop, recirculating, or auxiliary filtration. | ||

Performance Specifications

|
| ||
| 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. | ||
| 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. | ||
| |||
| Maximum Liquid Flow | This is the maximum liquid flow for which the filter is designed. | ||
| 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. | ||
| |||
| Maximum Pressure | This is the maximum pressure at which the filter is designed to operate. | ||

Materials of Construction
Back to Top
|
|
| ||
| Filter Media | |||
| 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. | ||
| 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. | ||
| 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. | ||
| 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). | ||
| Other | Other unlisted or proprietary materials. | ||

| 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. | ||
| Other | Other unlisted or specialized housing materials. | ||
