Burning Smell from....?

I have a new IR SS-5 compressor with less then 15 hrs on it and I started getting a burning smell, specially in the air.

It is in a 26 x 28 residential garage and wide open to air. I drained the oil and replaced but still the same,

I drained the tank and the first little bit it almost seemed like oil, a black milky water and then came clear approximately about a 1/2 cup in total drained out. I left open for a day then closed up and filled with air and right away the smell came back, any ideas?

Compressing air generates a lot of heat. Some of that heat comes off the motor as it's running against load, and more comes off the compressor head and line to the tank since smashing air molecules together generates a lot of friction, and that generates heat.

When you say the burning smell is in the air, do you mean around the air compressor, or coming out of the air line?

While I don't have details of your compressor model, I suspect it comes with a thermal overload switch, which should shut it off if the motor overheats beyond the norm.

You say you've changed the oil, and the oil level is good.

It may just be "new car smell". As the compressor heats up, the paint may be off-gassing.

I assume it's under warranty?

If it were me, I'd open the tank drain valve part way to let the air bleed, and I'd let it run continuously for a while.

I don't know if it's a continuous duty model or not. If it's not, shut it off after 15 minutes for an hour or so, then repeat.

Keep us posted, OK?
