Diablo Dry Air System

I run the Diablo filter housing with a Filter Techs sourced Lawrence Factor 13X Zeolite and Activated Carbon filter cartridge on my AV. No issues.

I run the Diablo Dry Air System and have an AV Compressor. The combination has worked flawlessly so far on about 15 fills of my 4500 PSI AV 74 CF carbon fiber Tank. The AV compressor does a good job of removing oil and water from the output via a metal cooling coil and a vertically mounted cotton filter. The weak links of the Diablo, in my opinion, are the input foster fitting shape and the output side hose (which is unamed and unmarked and these 2 characteristics always raise a red flag for me when dealing with HPA). I have been unable so far to determine the fitting thread size used on the Diablo - it is not BSP or NPT so I am guessing it is M10 x 1. I have some M10 fittings on order from Best Fittings UK. Hopefully one of these will fit. I intend to replace the foster fitting and replace the stock Diablo hose with an AV Compressor Output hose which is made in Germany and is rated at a Working Pressure of 630 BAR.

Regarding the AV compressor, it has exceeded all of my expectations and I am very happy with the performance. I run Coleman Powermate PX FULL Synthetic Oil and a mixture of filtered bottled water and Purple ICE. With this combination, in fills from 2500 to 4500 psi, my temps never get above 65C indoors.
