External regulator from the Czech manufacturer Altaros for filling cylinders with a valve with a standard DIN (G5/8) thread. This model can be used with all PCP air rifles that have a filling adapter with hose connection. The regulator maintains a stable pressure in the air cylinder and thus positively affects shot consistency and accuracy.
Thanks to the bleed screw, you can also use the regulator as a standard filling adapter. The pressure gauge and bleed screw can be rotated 360°. The package also includes a 300 bar hose with a G1/8 thread and a quick coupler adapter.
Pressure adjustment is done via a plastic screw that can be turned with a flat screwdriver. The total range from 100 to 210 bar corresponds to roughly 1.5 turns. Make each adjustment by a maximum of 1/4 turn and then check the resulting pressure on the pressure gauge. Unscrewing or tightening by more than two turns may cause the regulation to stop working. To increase the pressure, turn the screw counterclockwise; to decrease it, turn it clockwise.
