Oil filters
Selton offers a wide range of filters and filter elements for cleaning oil and hydraulic fluids. Hydraulic filters are devices for separating various kinds of contaminants from the working fluid of hydraulic systems and units.
You can buy a hydraulic oil purification filter by contacting the contact numbers listed in the Contacts section.
Types of industrial oil filters
Depending on the design features, installation location, and purpose, you can choose a hydraulic oil filter: partial flow, full flow, combined (depending on the volume of fluid passed through the filter); lattice, slotted, surface (due to design features); suction, pressure, drain (at the installation location, respectively: on the suction pipe, after the discharge pump, between the operating mechanisms and the liquid tank).
Purpose and scope of hydraulic filters
When operating modern hydraulic equipment, strict requirements are usually imposed on the purity of the working fluids as it relates to its efficiency, reliability and safety. During the operation of such equipment, it is possible that dust particles, oxides, condensate, rust, fibers, paints, and sealants may enter the hydraulic fluids. The presence of these contaminants in the hydraulic system leads to increased wear and destruction of the surfaces of many critical and highly loaded parts.
It is necessary to use an industrial oil filter for the hydraulic system to obtain the optimum level of purity of the working fluid, as well as reliable and long-term operation of equipment components and mechanisms.
The hydraulic filter is used in the following areas:
- hydraulic drives of transport and construction machines, mechanisms and devices of aviation equipment, machine tools and lifting and handling equipment;
- hydraulic amplifiers of industrial equipment and road machinery;
- stamping and pressing production;
- drilling equipment, logging equipment;
- compressors and transformers;
- hydraulic systems and equipment at oil refineries, chemical, mining and machine-building enterprises, food production facilities, and container and packaging plants.
Oil filters
The hydraulic oil filter is used to clean oils and working fluids of motors, transmissions, gearboxes, power steering from mechanical contaminants, as well as an oil purification element that filters and lubricates various equipment and systems.
Hydraulic oil filters are divided into the following types:
- Mechanical (paper, felt, mesh, plate, wire). Cleaning is carried out by filtration.
- Centrifugal. Centrifugal forces are used to remove inclusions. Gravitational. Impurities are precipitated by gravity.
- Magnetic. Separate contaminants that are attracted by a magnet.
Material version of hydraulic filters
The filter element for oil purification should be of good quality, with a manufacturer’s warranty. There are several main types of materials from which hydraulic filters for the hydraulic system are made:
- Mesh. The base of the filter is a mesh of thin stainless wire, the mesh size of which is very small. Such filters can separate only large particles. Therefore, they are mainly used as pre-filtration filters;
- Cellulose. Cellulose filter elements are characterized by a fairly high degree of filtration, but are not very durable. They are installed in systems that require regular maintenance;
- Fiberglass. Durable and efficient, they are characterized by a large capacity. They are more expensive than cellulose ones, but they last up to 4 times longer.
Our company has established the production of high-efficiency hydraulic filters. If necessary, managers will provide consulting support and help with the selection.
