INTRODUCING THE LW351...
The LW351 is a piston-sensed pressure regulator, designed specifically for drone and lightweight hydrogen fuel cell applications.

With a low 0.15% decaying pressure effect, it offers accurate control in a single-stage pressure reduction. When weight is a critical consideration for your application, the LW351 is the perfect solution. It's compact size and lightweight design (down to 0.2kg) fits the bill, and additionally offers direct mounting to the Hydrogen cylinder.

PLEASE CONTACT THE PRESSURE TECH OFFICE FOR PRICING.
