K4-20
TU 38.101759-78
Oil compressor K4-20 is produced from low-sulphurous nefty selective cleaning with method. Contains composition of the additives reducing formation of coke in the delivery line of the compressor, and also improving the greasing and antifoam properties. Oil compressor K4-20 is intended for greasing of piston ship air compressors of high pressure with the uniform lubrication system of cylinders and mechanisms of the movement.
