Air pressure vessels
Air tanks store compressed air for braking and other pneumatic systems. They serve as pressure reservoirs and are essential for stable, consistent system operation.
An air tank is a core component in pneumatic brake systems, acting as a buffer for pressurized air generated by the vehicle’s compressor. This air is used not only for braking, but also for auxiliary systems such as air suspension, lift axles, and trailer coupling mechanisms.
Vehicles typically feature multiple air tanks, each assigned to a specific circuit (e.g., service brakes, parking brake). These tanks ensure immediate air availability and help maintain consistent pressure even during repeated brake applications or under heavy loads.
Air tanks are constructed from steel or aluminum and come in various sizes, typically ranging from 5 to 80 liters. They feature threaded ports for fittings, drain valves, safety release valves, and occasionally pressure sensors to monitor internal conditions.
Corrosion, leakage, or mechanical damage can compromise air delivery and lead to braking failure. Routine inspections and proper tank replacement are essential for safety and compliance.
