In order to completely remove the water on that little compressor you will need more than just a water separator attached to the tank. Like Kevin said that small outfit is going to run almost constantly and because of this the air will get really hot which tends to keep the water from condensing in the tank and it will end up being expelled with the air, most of it anyway. A water separator is a MUST have but you can not attach it to the compressor tank outlet because the air is still too hot at this point for the separator to work, it may catch a small amount of water if located on the tank but not enough to make a real difference. Since this is to be a portable outfit you probably will not want to build a metal line air system so you will need to rig up an air cooler of some type to cool the air before it reaches the separator. This can be something as simple as running the air through a coil of hose placed in a tank of cold water or using something like an A/C evaporator core with a fan attached. Using an A/C core has been discussed some here in the past and although no one has gone into detail about a specific set-up it is fairly simple to do just make SURE!! that EVERY part is tested and/or rated for the pressure. Do a search on "Compressor" and you will probably find a lot of answers as this water problem has been covered in detail quite a few times here. Also Boss is right about draining that thing- do not completely drain all the pressure from the tank, there is absolutely no benefit from doing so and it will only add unnecessary wear on the pump/motor (however do drain the water regularly). Draining the tank of pressure often on a larger tank can shorten it's service life and cause premature tank failure due to excessive expansion and contraction but while that may not be much of a problem on a small tank like that 33 gal the pump/motor wear would be a concern.
