ALUM

Is an aluminum sulfate or filter alum. Acts in the range of 5.0 to 8.0 pH.

CONTAMINANT CAPACITY

The weight of a specified artificial contaminant that must be added to the influent to produce a given differential pressure across a filter at specified conditions. Used as an indication of relative service life. Also known as Dirt capacity, Dust capacity

BUBBLE POINT

The differential gas pressure at which the first steady stream of gas bubbles is emitted from a wetted filter element under specified test conditions.

FILTER ELEMENT

The porous device that performs the actual process of filtration. Also known as Cartridge

ADSORPTIVE FILTRATION

The attraction to, and retention of particles in, a filter medium by electrostatic forces, or by molecular attraction between the particles and the medium.

FILTER MANIFOLD

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

ACTIVATED CARBON

Is a specially processed carbon, used as a filter drier. Commonly used to clean air.

ADSORBENT FILTER

BRIDGING

A condition of filter element loading in which contaminant spans the space between adjacent sections of a filter element, thus blocking a portion of the useful filtration.

BURST PRESSURE RATING
