>I probably have a similar compressor and I leave it pressurized all the time. You should open the drain valve at the bottom to blow the moisture out as recommended in your manual.

Piping around your shop should be installed with the maximum air-flow required at the tool in mind. You may find that the compressor is limited in handling these tools even without piping considered. I don't know if your 4.5HP is real HP or the over-inflated numbers some manufacturers use. If it plugs into a 120V outlet then the real HP is more likely to be around 1.5HP. HP is not really the number you want to look at for air compressors/tools. It is the maximum flow that the compressor will deliver at the desired pressure. These are often listed at about 40PSI and 90PSI.

If you are going to use a nailer or just blow dust then any piping will be fine. Threaded steel piping is often recommended but isn't easy for most people to handle due to cutting and threading. Copper water pipe is more expensive but can be easily and safely used with soldered joints although you should make sure you have good soldering technique. Like water use, the more flow and less pressure drop you want means increasing the size of the pipe.

Do not use PVC plastic pipe. The pressure ratings are adequate but for use with air (air is compressible, water isn't) it can rupture and blow sharp plastic shards all over the place. There are plastic pipes rated for compressed air use so if this is your plan make sure you have the right stuff.

Hope this helps a bit to get you started.

>Your compressor is a bit on the small size, so don't expect miracles from it. You should be able to do spray finishing, clearing shavings with a blow gun and similar things with no problem. Sandblasting and other tasks that use huge amounts of air probably won't be possible without a larger compressor.

If you install piping for compressed air, use galvanized pipe and fittings. Forget PVC pipe. I know it's easy to work with, but it's not considered safe for compressed air. In colder temperatures, it can actually explode. Be sure to install your piping with a bit of slope and a valve to drain any moisture that may collect. It's okay not to drain the air from your compressor tank after every use, but don't leave the power on. You should disconnect any air hoses to take off the pressure. Be sure to drain the moisture from your compressor tank frequently, too. Have fun with your new toy.

>Thanks for the replys. Much appreciated. My main use will be for dusting purposes and the occasional nail gun use. I don't anticipate heavy usage.

Thanks again!
