Oil K3-10 (TU 38.401724-88) is produced from a mix of low-sulphur petroleums by method of selective clearing. Contains a composition of the additives reducing formation of adjournment of a deposit in a delivery line of the compressor, and also improving antioxidizing, anticorrosive, greasing and antifoamy properties.
It is intended for greasing of piston compressors with temperature of forcing to 200°С, and also rotational compressors.

Data on operational temperatures represent values which are guided by a structure of lubricants, and also on a scope and technology of use. Depending on a kind of mehaniko-dynamic loading lubricants change the consistence, conditional viscosity or viscosity at various temperatures, pressure and duration of operation. These changes of indicators can influence work of components.
