This is the newer model (Model number should be 0523-101Q-SG588DX) and can easily produce air flow to 18 ft deep. May I ask where you found it? And is all you get for $380 is a compressor, power cord and shipping? The compresor will need an intake air filter which I can tell or show you how to build / create your own homemade version. Outlet & inlet ports will be 1/4" std plumbing thread size.
