I have an old RRTI RRU30 recovery unit that I need to change the oil in. It says use 3GS compressor oil. Can't find it. What kind of oil you guys use?
I think I used zerol 200 in mine without problems.
Unit was retired long time ago. Memory is fuzzy.
RRU30, slow but reliable. I used 3GS in mine.
Johnstone Supply lists the 3GS Nu-Calgon and Suniso brands in their catalog.
Any 150 viscosity Mineral Refrigeration Oil should work fine.
You still using big blue. Wanna buy mine? It's still in the box.
You need to put the phone down and get back to work!
