Overview
INTRODUCING THE AUTO438...
The AUTO438 is an EC79 approved piston-sensed pressure regulator, designed specifically for Hydrogen fuel cell buses and trucks. During the EC79 testing process, it has been put through over 100,000 cycles by external certification body, KIWA Nederland B.V. - equating to 10 years life time on a typical installation!

With a balanced main valve as standard, it offers stable control of outlet pressures up to 20 bar (290 psi) from a maximum 438 bar (6,350 psi) inlet pressure.
