Similar in functionality to the aforementioned Splitter, but these are used for self-install variants of ADSL. They usually present two sockets as before, but instead of replacing the master socket faceplate, they plug-in to the original one
Also known as a splitter, a microfilter is a device that splits an analogue telephone line into two independent services: a low frequency range (ca. 20Hz - 20kHz) used for voice and fax service, and a higher frequency range (30 kHz - 1 MHz) suited to high speed data transfer (DSL). Each main or extension socket must be fitted with a microfilter in order to prevent interference between the two frequency ranges.
Microfilters are devices that connect between your telephone and phone jack. DSL service allows voice and data to share the same pair of wires, microfilters keep the signals from interfering with each other.
Otherwise known as ADSL splitters. You will need a microfilter for each phone socket at your premises. The splitter separates the ADSL (high frequency) signals from the analogue phone (low frequency) ... more
Membrane filter used to trap microorganisms suspended in water. Filters are usually installed on dental unit waterlines near the point of use as a retrofit device. Microfiltration commonly occurs at a filter pore size of 0.03 to 10 microns. Sediment filters commonly found in dental unit water regulators range from 20 to 90 microns pore size and do not function as microbiological filters.
