Jun-Air air compressors are normally sold at industrial compressor and compressed air component distributors, and from some specialty distribution outlets such as dental and laboratory supply houses.

These slick air compressors appeal to the specialty air compressor market because Jun-Air air compressors are among the quietest available, anywhere in the world.

Change Jun-Air oil

There are resources on line that show how. As far as I’m concerned, since the site glass is close to the the lowest point in the sump, the easiest way may be 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 with fresh oil.
