How to switch the compressor lubricating oil filter?
Thread Content
As the title suggests, how do I switch the compressor lubrication oil filter?
1. First, fill the spare filter with oil; after venting, close the vent valve. 2. Then slowly turn the cock to the middle position and then to the position corresponding to the spare filter
Exhaust, pressure equalization, oil filling – switch slowly

3# It is said on the 3rd floor that a gradual transition should be made. If the pressure at the lubricant outlet is too low during this gradual transition, will an interlock be triggered? CHINATZ
Cock: a transliteration of “cock”, which refers to a stopcock. The so-called cock is called a stopcock in ancient terms. The valve attached to the level gauge installed on the boiler/container. This is what is used to connect the pressure gauge to the elbow. Hey, fellow traveler upstairs, I’m also just starting to learn it. :)
It’s better to switch quickly; switching slowly affects the oil pressure
There is a connecting valve between the oil filter cartridges; it can be opened slowly to fill the spare cartridge with oil. Then the top exhaust valve is opened until oil flows out continuously, after which it is closed. Finally, the connecting valve is closed, allowing for the switchover.
What was said on the second floor is correct: exhaust and fill with oil first, then make the switch.
One more thing: the speed of the switching process depends on the design; older filters could be switched quickly, as they could be moved into place in an instant； Now it can be cut slowly; the slower, the smoother it is, with almost no fluctuations in oil pressure.
The key is to first fill the backup filter with oil; once it’s full, a gradual switch-over can be made. We performed the switch-over several times, and there was basically no change in pressure
