I live in northern Indiana and sometimes in the winter it gets below 0 I have a 60 gallon two stage 5 hp compressor with an open frame motor, so it is exposed to the dust. I have been thinking about putting in the lean-to out side in order to get it out of the dust and make some room, not to mention get the noise out of the shop. I am just concerned about it out in the cold as far as the oil being to cold and the lines condensating with the change in temp as the air comes in the shop and causing problems. I just don’t shorten the life on a compressor that should last another 20+ years. any thoughts???

I live in the St Louis area so I get my share of cold weather . I have my compressor outside in it’s own small insulated building. Wired in a small electric heater to a thermostat that goes down to 30 degrees so I set it just a little higher so it won’t go below 32. Also installed a remote wireless thermometer that reads inside so that I can insure that the heater and thermostat are working.

To compensate for the heat buildup during the summer, I set up the roof so that I can prop it open it to let the excess heat escape.

Inside the shop, the air goes through over 40 ft of copper tubing to act as a cooler to keep the condensation reduced. After the 40 ft, the air then goes through a water separator to get rid of more condensation. After the separator, it is plumbed out to each station where there is a drip leg installed to catch more condensation. The drip legs are drained every month whether they need it or not.

Your going to have condensation where ever you put it that is just a fact with air compressors. Put a moisture separator on it (install the separator where it won’t freeze) and moisture traps with drain valves at all your drops. Drain the tank of moisture periodically. The moisture doesn’t harm the compressor so much as contaminating the surface of whatever your blowing off or finishing. I’ve worked in a lot of shop where the compressor was in an unheated area and as long as the system is installed properly to catch and drain moisture. They have lasted a long time.

Puzzleman was posting same time. Everything he said is good. If you don’t have room for 40 ft of line before the water separator. You can get by without it. All the lines should drain toward the water traps or drip legs. The heater is a good idea. Insulate the lean-to well. The whole deal with the moisture is to trap it and drain it before it can contaminate your work. Moisture is a by product of compressing air The higher the humidity and the greater the temp changes the more your going to have.

Forgot to mention that the compressor has an automatic drain valve that keeps the moisture out of the tank by releasing pressure every 10 minutes for 4 seconds.

I did not see any one mention useing synthetic oil .May just fix the problem . I remember it would get so cold truck would start moving before i put it in gear ,changed out all my gear oil and also made the truck feel smoother .seems like changing your compressor over is a no brainer , it will also most likely improve it’s life .I did my compressor when framing in colorado and it solved the slow start problem .

When I lived in the mountains, a local garage had problems starting his compressor. The oil would get so thick that the circuit breaker would trip when starting. Switching to a synthetic oil solved the problem.

Josephf, that was going to be my suggestion.

I put synthetic oil in all my compressors regardless of where they are used, just helps them start easier and they last forever. I have one I bought in 1985 and it still runs fine…
