Filtrimõõt

Filtrimõõt refers to the characteristic size of particles that a filter is designed to remove. It is a critical parameter in filter selection and performance evaluation, as it dictates the smallest particles that can be effectively retained by the filter medium. Different industries and applications utilize filters for various purposes, from water purification and air filtration to industrial processes and medical devices. The specific filtrimõõt required for a given application depends on the size of the contaminants to be removed and the desired level of purity of the filtered substance.

Filters are often rated using several different metrics, including nominal and absolute ratings. A nominal filtrimõõt indicates the particle size that the filter is expected to remove with a certain efficiency, often around 90%. This means that while the filter is designed to capture particles of this size, a significant portion of smaller particles may still pass through. An absolute filtrimõõt, on the other hand, specifies the particle size that the filter will remove with extremely high efficiency, typically 99.9% or more. This is a more stringent measure and is crucial for applications where even very small contaminants can have detrimental effects.

Understanding filtrimõõt is essential for selecting the appropriate filter to achieve the desired separation. Factors such as flow rate, pressure drop, and the nature of the fluid or gas being filtered also play a role in filter selection, but the filtrimõõt remains a primary consideration for determining filtration effectiveness.
