Eastwood sells the same unit with and without the DevilBiss branding. The one that isn't branded as DevilBiss is sold as a complete filtration unit or something like that, which combines drying and filtering functions.It's not a very good setup. You'll get moisture through it pretty quickly.An alternative use is to use it as a desiccant dryer only. They sell silica gel cartridges for this instead of the total filter thing and once spent, it's possible to pry them open and refill the silica countless times. Some people even bake the silica to reuse it but I recommend against that because there's always some compressor oil in it too and you get a nasty mess.Best setup is to first use at least 50 feet of tubing and then a condensation separator to remove most of the water, followed by something like this as a desiccant filter, followed by particulate filters.Even nicer is a refrigerated dryer, of course.
