Hella UP28

Reference: 8TG009 428-087

The cost savings and energy advantages of conventional brake systems equipped with a pneumatic brake booster can also be applied to advanced vehicle technologies such as future downsized engines and hybrid/fuel cell vehicles by incorporating a vacuum pump. These pumps are able to supply the necessary vacuum independent of the engine technology. The UP28 supplies a vacuum to the brake booster, and when required, to the engine compartment actuators.
