The model AT09 LPG reducer is a single stage reducer for LPG sequential injection systems, homologated ECE 67R-01, originated from the previous model AT07. The AT09 reducer is equipped with an integrated filter unit and an inlet solenoid valve. The pressure at the outlet is adjustable from 0,9 to 1,8 bar (pressures referred to the reducer not connected to the engine).

Available in 3 different versions:

- STANDARD: without additional heating
- ALASKA: with additional post-heating of the LPG at the outlet, that allows higher gas flow and higher gas temperature at the exit.
- ARTIC: with additional pre-heating of the liquid LPG at the inlet, that allows extra higher gas flow and higher gas temperature at the exit.
