meter

a separator that uses a magnetic field to attract and hold ferromagnetic particles.

a filter element that, in addition to its filter medium, has a magnet or magnets incorporated into its structure to attract and hold ferromagnetic particles.

strategically located in the flow stream to collect a representative sample of wear debris circulating in the system: for example, engine swarf, bearing flakes, and fatigue chunks. The rate of buildup of wear debris reflects degradation of critical surfaces.

A seal that uses magnetic material (instead of springs or a bellows) to provide the closing force that keeps the seal faces together.

a filter assembly containing multiple ports and integral relating components which services more than one fluid circuit.

a filter in which the inlet and outlet port axes are at right angles, and the filter element axis is parallel to either port axis.

A publication containing health and safety information on a hazardous product (including petroleum). The OSHA Hazard Communication Standard requires that an MSDS be provided by manufacturers to distributors or purchasers prior to or at the time of product shipment. An MSDS must include the chemical and common names of all ingredients that have been determined to be health hazards if they constitute 1% or greater of the product’s composition (0.1% for carcinogens). An MSDS also included precautionary guidelines and emergency procedures.

material passed into the effluent stream composed of the materials making up the filter medium.

the porous material that performs the actual process of filtration. The plural of this word is "media".

Million

oxidized ferrous particles which are very old or have been recently produced by conditions of inadequate lubrication. Trend is important.

Any lubricant, usually petroleum-based, that facilitates the cutting or shaping of metal. Basic types of metalworking lubricants are: cutting and tapping fluids, drawing compounds, etc.

Millionth

See Micron.

a unit of length. One Micron = 39 millionths of an inch (.000039"). Contaminant size is usually described in microns. Relatively speaking, a grain of salt is about 60 microns and the eye can see particles to about 40 microns. Many hydraulic filters are required to be efficient in capturing a substantial percentage of contaminant particles as small as 5 microns. A micron is also known as a micrometre, and exhibited as ¦m

a method of particle counting which measures or sizes particles using an optical microscope.

Thousandth

oil derived from a mineral source, such as petroleum, as opposed to oils derived from plants and animals.

A distillation fraction between kerosene and gas oil, widely used as a solvent oil in gas adsorption processes, as a lubricant for the rolling of metal foil, and as a base oil in many specialty formulations. Mineral seal oil takes its name – not from any sealing function – but from the fact that it originally replaced oil derived from seal blubber for use as an illuminant for signal lamps and lighthouses.

capable of being mixed in any concentration without separation of phases; e.g., water and ethyl alcohol are miscible.

A compound, often of petroleum origin, for coating the interiors of molds for glass and ceramic products. The mold lubricant facilitates removal of the molded object from the mold, protects the surface of the mold, and reduces or eliminates the need for cleaning it.

Molybdenum disulfide, a solid lubricant and friction reducer, colloidally dispersed in some oils and greases.

A black, lustrous powder (MoS2) that serves as a dry-film lubricant in certain high-temperature and high-vacuum applications. It is also used in the form of pastes to prevent scoring when assembling press-fit parts, and as an additive to impart residual lubrication properties to oils and greases. Molybdenum disulfide is often called moly or molysulfide.
