Air compresor outside OK?

Good advice all! Desert Rat, hows that Puma? Same brand as the one I just bought so just wondering on the quality. I will have it next to the garage so really only need a roof and 2 posts to make a shed, leave the top foot open all around or put louvered vents. Yes I will put some pads under it and the breaker is inside the house so I either need a sub panel or a HD switch.
OK I will start on the cement this weekend!
