SOG-913KT1ФB3 liquid purification unit is intended for purification of highly-contaminated petroleum-based liquids (expect highly flammable liquids with flash temperature lower than 40ºC) from mechanical contaminants and non-solute water, i.e. substances with density greater than the density of purified liquids. This modification of liquid purification unit is capable of prefiltering of liquids. The unit can be made explosion-proof and can be equipped with continuous water extraction line.

The unit can be used to maintain the purity of liquids used in production, repair and technical maintenance of aircraft vessels, gas pumping equipment, road construction vehicles, engines, processing units, technological and other equipment. This can improve the stability and longevity of hydraulic lubrication systems and aggregates as well as the quality of processed surface; it also can lead to increased service period for process liquids and oil, thus reducing environmental impact from the equipment.

The unit utilizes precise explosion-proof electrical equipment with a group II explosion-proof shell (as specified by GOST (State Standard) no. P 51330 0-99 and GOST no. 12.2.020-076) and bears the following markings of explosion-proofing: 2 Exed II CT6.
