Air Tank

Air Tank — Brake System Compressed Air Reservoir

An air tank, as part of truck and bus brake systems, is a metal-housed component that stores compressed air produced by the compressor and supplies it steadily to the brake circuit. Safe and reliable brake system operation depends on continuous and adequate air pressure availability; therefore, the air tank serves as the energy storage unit of the system. With every brake pedal press, the required air is already accumulated in the tank and delivered to the system without pressure loss, even during sudden demand.

The product range includes air tanks of various capacities and mounting types, discharge valves that remove moisture and contaminants from the tank, connection flanges, support clamps, and coated housing options that protect the tank surface against corrosion. Additionally, seal kits and fasteners are available to maintain system integrity, providing solutions for both complete replacement and partial maintenance needs.

• Primary and secondary air tanks in various capacities
• Discharge valve, connection flange, and support clamp groups
• Corrosion-resistant coated tank housings
• Seal and fastener kits

When selecting an air tank, correctly determining the volume and connection size to match your vehicle's brake system architecture is essential for efficient operation; parts manufactured to match major truck and bus brands are compatible and reliable across different vehicle groups. During routine maintenance, checking the functionality of the discharge valve, monitoring the tank housing for corrosion or damage, and proper maintenance contribute to long-term and safe brake system operation. Selecting the correct part balances both driving safety and the load on other system components.

Frequently Asked Questions

What is the purpose of an air tank? It stores compressed air from the compressor and supplies continuous air flow to the brake system and other pneumatic equipment.

What are signs of air tank failure? Brake pedal stiffness, pressure gauge drop, moisture accumulation in the tank housing, or air leak sounds are common indicators.

When should an air tank be replaced? Replacement is necessary when corrosion, cracks, or irreparable air leaks are detected, or when the discharge valve loses function.

How to select the correct air tank? Choose a part that matches your vehicle's brake system volume requirements, connection size, and mounting location.

How is the air tank related to other brake system components? Pressure in the air tank provides the necessary air source for healthy operation of components such as ABS, regulator, exhaust brake, dual-circuit protection valve, ABS electronic control unit, and ABS circuit valve.

Why is moisture accumulation in the air tank important? Moisture in the tank over time can cause corrosion in the housing and blockages in valves, so it must be regularly drained.

How is air tank maintenance performed? Maintenance is carried out through periodic checking of the discharge valve, inspection of the tank surface for corrosion, and verification of fastener tightness.
