Young Ankai Haige bus dryer assembly (with four-circuit valve)
KL3511FG
Product Description
Safeguard the integrity and safety of your bus’s pneumatic brake
system with the KL3511FG Air Dryer Assembly, expertly manufactured
by Nanjing Dingguan Auto Parts Co., Ltd.
This is a mission-critical component designed for Youngman, Ankai,
and Higer buses. Its primary function is to efficiently remove
moisture, oil, and other contaminants from the compressed air
before it enters the air tanks and braking system. By delivering
clean, dry air, this assembly prevents internal corrosion, valve
freeze-ups in cold climates, and premature failure of pneumatic
components, significantly extending the life of your entire brake
system.
What sets this unit apart is its integrated four-circuit protection valve, a vital safety feature. It intelligently isolates the air supply
into independent circuits for the front brakes, rear brakes,
parking brake, and auxiliary systems. This ensures that a sudden
pressure loss in one circuit does not compromise the entire braking
system, maintaining critical stopping power and ensuring maximum
vehicle safety.
Key Features & Benefits:
- Part Number: KL3511FG
- Application: Youngman, Ankai, Higer Buses
- Enhanced Safety: Integrated four-circuit valve preserves braking function in case
