Tomasetto AT12 SUPER RMAT3880 CNG Pressure Regulator for up to 335HP

New redesigned version for 2019, it replaces older AT12 SUPER (code RMAT3820).

Tomasetto CNG pressure reducer model AT12 is a 2 stages pressure reducer for sequential injection systems.

Compact and very reliable, it is certified in accordance with ECE R110, approved in accordance with Enargas, Inmetro and other local regulations, and complies with ISO 15500 standards. The outlet pressure is adjustable from 0.12 to 0.25 MPa to for best performance. The reducer inlet is has adjustable swivel fitting, which has the connection for pressure manometer.

In the new version "year 2019", main body shape has been modified in order to improve heating circuit and to allow the use of bigger water fittings d.16 mm (when needed); it is also possible to put water fittings in 2 different layouts (parallel or at 90° like in previous version) with the aim to ease the installation.

Tomasetto CNG AT12 pressure reducers is available in two versions: STANDARD and SUPER.

  • Model AT12 Standard version is a 2 stages reducer, equipped with a low pressure solenoid valve (to be used with in-line CNG Cut-Off valve).
  • Model AT12 Super version is a 2 stages reducer, equipped with an integrated high pressure solenoid valve at the inlet. This version allows not to use an in-line solenoid valve in the system and gives higher performances, in terms of gas flow.

    Tomasetto Reducer

    Posted by Florian on 11th Feb 2020

    Used it on two cars now. It works very good.
    Compared to the Necam Reducer my Volvo was fitted with before, it is much more easier to understad. It looks like it would last long and would be easy to srevice. Using it on a Volvo V70 I had to reduce the spring tension on the low pressure stage. Volo needs only one Bar on the low pressure side and the Tomasetto reducer adjusting range starts at 1.2bar at sock configuration. Since i am german i am sorry for my bad english.
