The Mini SFR is Redline Airsoft's new HPA regulator. The Mini SFR has the exact same performance and features as the class leading standard SFR regulator, but in a smaller package.
The main change is that the UFA has been eliminated and the tank now screws directly into the bottom of the regulator. The regulator is only 2.8 inches tall, with the hose output now on the side rather that the top.
Just like the standard SFR before it, the Mini SFR is a fully balanced regulator. Why is having a balanced regulator important in Airsoft?
Unbalanced regulators are subject to what is known as the "supply pressure effect." That means an unbalanced regulators output pressure is affected by changes to its input pressure.
Unbalanced regulators can have a very large pressure change as their supply tank empties. This can cause a velocity to drop as the supply tanks pressure drops.
Since the Mini SFR is balanced, its output pressure is unaffected by changes to its input pressure. That means even as the tank empties, the Mini SFR's output pressure, and therefore the guns velocity, will remain unchanged. This allows you to shoot the air tank virtually empty with no performance decrease. Effectively giving you more shots per tank.
The SFR and the Mini SFR are the only fully balanced regulators sold for Airsoft use.
