Changing Jun-Air Oil

There are resources online that show how. As far as I’m concerned, since the site glass is close to the lowest point in the sump, the easiest way maybe this.

I would open the oil vent at the top of the pump, then, with care as it will be a mess, remove the sight glass. Oil will pour out, and as it does, tilt the pump towards the sight glass to drain as much of the oil as possible.

Replace the sight glass and fill it with fresh oil. Oil change video: Changing to a different oil in Jun-Air compressor

Our junair, 6 gallon, has started emiting an oily smell. Oil level is good and is monitored and drained regularly. Use only junair oil.

Maybe it’s working too hard.
How long from empty to full tank? When it gets to full, is it at 8bar/120psi? Does it hold there?

I have a Jun Air 6-15 oil lubricated compressor – Absolutely bulletproof! My question is – to use for airbrush painting at up to 40psi, does it need an air filter AND an oil filter?

If you haven’t already, please read here:

Compressed Air Filtration Guide – Types of Filters & Their Purpose

Then if you still have a question (or three) reply here…

Bottom line, though, is it depends, and you pretty much have to experiment until you get what you need.
Alternatively, buy yourself a airbrush compressor. It might actually be cheaper in the long run.

I have a jun air compressor i would like to add a tank and use for airbrushing what components are needed to complete this project. Also it does not have just a power plug can one be added for this and how should the wiring be done. It is a jun air of332 the label says 110v and 220v i suppose it can be configured for your needs.

Thanks for any help

Couple things –
Where are you? By which I mean what Voltage are you dealing with at the outlet?
I don’t see a 110/220V version – how about you send a pic of the label that says that?
The model you have has no tank at all? Then you need to come up with one rated at 200psi or so, given the 175psi of the ‘motor’ (what Jun-Air calls it). There’s an alternative to that, but it’s probably wasteful.
Finally, what brushes are you planning to use? What pressure and CFM are they?

I have a jun air compressor oil less has two 240v electric motors the model is 4000-40BD3 and has no power connector plug.it also has 2 sets of wires 3 each and I need help with the power plug connection wiring? Any assistance will be greatly appriciated

You can google electric plug connections for your country and get your answer.
