Introducing the all-new Empire FLO Pro series 4500psi HPA tank regulator. The result of three years of development and refinement, the FLO Pro regulator gives you the perfect combination of reliable performance and optimized features.

An industry first, the FLO Pro allows you to adjust its bonnet to your liking while your air system is under pressure*. With this feature, you will never have to worry about the regulator's fill nipple or pressure gauge digging into your wrist.

The FLO Pro regulator's balanced piston allows for optimal airflow and delivers consistent pressure to your marker. Speaking of pressure, the FLO Pro's output pressure is adjustable from 500psi to 800psi**.

Available in Black, Red, Blue, and Gold, the FLO Pro regulator also features all-new low profile fill nipple, gauge, and burst disk assemblies.

* An Empire FLO Regulator Tool (Sold separately) is required for bonnet adjustment when air system is under pressure. If you do not have the FLO Regulator Tool, you will need to degas your air system prior to adjustment.

** The air system must be completely empty before adjusting your FLO Pro regulator's output pressure.
