The Knorr K179470 dual air pressure sensor (Part Number: K179470) is a critical pneumatic safety component designed for FAW J6, JH6, and J6P heavy trucks. Fitted to the air dryer assembly, it safeguards brake system air supply and pressure management.
Essential Protection for Heavy Truck Pneumatic Systems
Maintaining stable compressed air pressure is essential for air brake safety and auxiliary system performance on long-haul commercial trucks:
- Pneumatic Brake Safety: Monitors dual air circuits to prevent brake drag or pressure loss while hauling heavy payloads.
- Air Dryer Cycle Control: Delivers accurate pressure feedback to manage air compressor unloading and desiccant purging cycles efficiently.
- Chassis-Grade Durability: Built to withstand harsh under-chassis exposure, temperature swings, and vibration on highway and construction transport routes.
