- Adjustable output pressure up to 140 PSI
- CNC-machined T6 aluminium construction
- Designed for low-pressure and high-flow HPA engines
The MechLabs FLO MAX is a high-flow HPA regulator designed to provide a stable, consistent supply of air, even when paired with demanding HPA engines. Its enlarged internal air channel increases airflow capacity, helping prevent air starvation during high-rate-of-fire and high-demand setups, including the Nexxus full-auto firing mode.
The FLO MAX is designed to work across a wide range of HPA engines, from lower-pressure systems through to high-flow platforms. Its high-volume airflow helps maintain consistent performance under load, while the integrated TS On/Off module provides greater control when pressurising and depressurising the regulator.
The On/Off function allows the regulator to be safely pressurised or depressurised at the press of a button, reducing stress on the regulator threads and helping prevent accidental shots during handling or maintenance. The redesigned module also improves internal airflow for smoother and more consistent air delivery.
Built for durability, the MechLabs FLO MAX features a CNC-machined T6 aluminium body with an anodised finish for increased resistance to corrosion and wear. A quick-connect (QC) valve also makes maintenance and cleaning straightforward, while output pressure can be adjusted using a standard ⅛" hex key.
