"Centercut"I agree with @LDP concerning the filter. It certainly doesn't look like the "gold" filter we've been using with Zeolite. It appears to be the same as the AV, with the cotton tampon inside. The "built in dessicant filter" is the same as the Tuxing outlet valve block, pretty much useless, holds about 20 to 25 beads tops, enough for maybe one fill if you're lucky. Best thing to do with that is to remove the silica beads that come with it before they become wet and cause corrosion, and replace with another small cotton tampon filter. If you buy the Hatsan, it'll still be a good idea to add a "gold" filter with Zeolite 13X.
The Hatsan still appears to be built on the Tuxing two cylinder platform, as is the AV, but adds the digital gage/control center and the auto blowdown feature. Right now, for the money, the best deal in compressors is the "like new" Daystate 115vac models they have at AoA for $1895. And the runner up, in my book, would be the Alpha Carette (AC).
In all fairness in disclosure, I do not own the Daystate or AC compressors. I own a two cylinder Tuxing which has worked well for about 1/2 a year now, no problems. I do have the "gold" filter that I use with 13X Zeolite and "salt" the beads with color changing Silica beads. Its hard to accrue much run time since it tops off my 60 min (88 cubic feet) SCBA tanks very quickly, less than 15 minutes normally from 3200 to 4500 psi. I only have about 4 hours run time on mine. The cooling system modifications I made are working great with no issues or problems.
