Description: The Max Flow has a self-adjusting regulator so you can air up and not worry about your output pressure. No other tank on the market can self adjust without the use of a secondary regulator. Forget about pressure spikes that can cause your velocity to jump up or down because players who have to have the best equipment possible designed the Max Flow. The Max Flow avoids spikes by releasing excess pressure thru vents until the pressure equalizes. Another cool feature is the tank screws on and off the main regulator for easy transportation. This tank will work wonders on any marker.
