Redline SFR Full Air Regulator System

The Redline SFR is the Ferrari (or Lamborghini/Pagani/whatever your favorite is) of airsoft regulators. Designed specifically for airsoft in mind the SFR is the successor to the popular Redline Firebase.

SFR stands for "Super Fast Refresh" which is exactly what it does. With the high flow refresh by this regulator your shot to shot consistency with your HPA system of choice is outstanding.

The SFR is a fully balanced regulator. Why is that important? Unbalanced regulators are subject to what is known as "supply pressure effect." That means the 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. Importantly on some types of regulators, that pressure change can cause the regulators output pressure to rise as the supply tanks pressure drops.  That can result in an undesirable situation since any rise in output pressure will cause a corresponding rise in velocity.

The SFR's output pressure is unaffected by changes to its input pressure. That means even as your tank empties, the SFR's output pressure and therefore your velocity, will remain unchanged.
