1972 Jun-Air Model 6... as vintage as me.

1972 Jun-Air Model 6... as vintage as me.

I am looking for any info related to a 1972 Jun-Air Model 6 and what is appropriate oil to use/where to get it. Any other pointers to DIY support to maintain and/or rebuild are also greatly appreciated. The compressor is a USA model with a 15 liter tank under it and a .5HP motor.

replacement for holding tank/SteveUK
by: Martha

Hey StevenUK. Totally missed your post. I did find someone to do some MIG welding on the hole. So good so far. Do you still have the holding tank? By now I guess it has been long gone. ??

Hi I have the same old unit (same gold/green colors). It's in nice condition and I want to change the oil.

Did the SJ-27 oil work for you?

THe model number
by: Martha

Hi . . me again. THat model is so old and when it was made Model 6 was it's only designation. They had not yet started creating the 6-X naming system. By all visible examination the Model 6 is the first version of 6-15 exactly. But I have been told by USA rep that none of the Newer 6-15 parts will fit on my old Model 6.

Jun-Air Model 6 vintage 1976
by: Martha

Oh my goodness. I cannot find parts etc. They all want to sell me a new on and all I need is a new air holding tank. I've had my compressor for sometime. about 18 years or so.

I have problems with my tank. A small hole has developed on the underside of my holding tank and It is spraying out air etc. I've been told it's obsolete etc. No parts available.

Not sure about having that hole welded or having someone replace the whole lower half of the tank itself. So frustrating. The motor runs perfect. Never had any problems with it EVER. . . til now.

The last time I ordered Syn oil it was from the USA jun-Air in MI I think. Anyway it was the SJ 27 made in Denmark.

I got no help from statewide reps on my tank issue. I'm preparing to write to Denmark etc, but I have this bad feeling that the company has been sold off. If that's the case it does not make me happy at all.

If you ever decide to sell give me a holler. I just love mine. . so sad it needs a new tank. . . : ((

oil alternatives
by: alison

If my compressor uses the SME 7050 synthetic compressor oil SJ-27, Can't i just switch to using a 10W synthetic compressor oil?

Juna-Air Rep Replied
by: Jan

The regional rep. said that they only have the SJ-27 and did not know what the specs were for SB-42, the original oil spec back in 1972. Bambi still has an oil they call SB-42/46 available in the UK. I am going to try the SJ-27 and see if it works OK.

Oil specified
by: Jan Nelson

The Model 6 here does not have any other designation e.g. -XX however it is attached to a 15 liter tank, so might be equivalent to the current Model 6-15.

There is a label on the motor that specifies using SB-420IL oil. I have no cross reference for that. Does anyone know if the current synthetics are direct replacements for that spec lubricant?

Jun Air Oil
by: Bill

As noted earlier, the specs call for SJ-27 synthetic compressor lubricating oil. Since that is the recommended oil for Jun-Air compressors, by Jun Air, I can only assume it would suit your compressor.

An email to Jun-Air wouldn't hurt, I would say.

Re: 6-XX, could be. There is no sign of just a Model 6 in today's line up at Jun Air.

Model definition
by: Jan Nelson

The labels only show Model 6 without any -XX after. Since it is mated to a 15 liter tank, would that imply a 6-15?

The oil indicated on a label on the unit is SB-420IL. Is there a cross reference for this?

Oil for Jun Air Model 6
by: Bill

The specs call for SJ-27 synthetic compressor lubricating oil.

Complementary alternatives are available: SME 7050 Synthetic Compressor Oil SJ-27 Compatible 24oz

You can browse for the most competitive source for the lube oil.

Typically the model 6 also had a suffix, such as 6-4 or 6-15. Can you determine if your model has such?
