Double Chamber Air Tank Air Receiver Compact Integrated Air Tank for Railway Freight Wagon

Double Chamber Air Tank Air Receiver Compact Integrated Air Tank for Railway Freight Wagon

Product Overview

Double chamber air tank, also known as double chamber air receiver, is a specialized integrated pressure vessel for railway freight wagon air brake systems. Unlike traditional split dual-tank setups and general-purpose compact air tank products, it combines two fully independent air chambers in a single welded cylinder. This integrated design eliminates the drawbacks of scattered installation, heavy weight and complicated piping of conventional dual air storage systems.

Built with an internal solid partition, this double chamber air receiver features completely isolated 50L auxiliary and 11L operating chambers with zero cross air leakage. Its compact one-piece structure saves substantial underframe space, reduces pipelines and fasteners, and lowers wagon tare weight. Engineered for harsh railway operating conditions, this reliable compact air tank is widely compatible with K3, K13 hopper wagons and GQ70, GN70 tank wagons, serving as a core component for standard railway freight brake systems.

Differentiated Core Advantages (Vs. Ordinary Dual & Compact Air Tanks)

• 1. Railway-Grade Isolated Dual Chambers: Ordinary compact air tanks adopt single or semi-separated structures with air mixing risks. Our double chamber air tank uses a thickened integral partition to ensure 100% independent air storage for auxiliary and operating circuits. A stable 0.6MPa working pressure delivers accurate brake response, adapting to railway vibration, jolts and extreme temperatures.
• 2. Ultra-Compact & Lightweight Integration: Replacing bulky split dual-tank assemblies, this double chamber air receiver integrates two functional chambers into one unit. It saves over 30% installation space and 25% supporting accessories, perfectly fitting limited wagon underframe space, reducing vehicle weight and lowering operational energy consumption.
• 3. Strict Pressure Vessel Quality Assurance: Made of premium Q245R/Q345R pressure vessel steel, all welds undergo 100% NDT. Every unit passes 1.2MPa hydrostatic and 0.7MPa air tightness tests before delivery. It meets TB/T and GB150 standards, with optional EN 286 certification for EU markets, outperforming ordinary industrial compact air tanks in safety and durability.
• 4. Customizable Heavy-Duty Corrosion Resistance: Featuring professional sandblasting and railway-grade heavy-duty anti-corrosion coating, this double chamber air receiver withstands long-term outdoor use and ocean transportation. Optional hanging brackets, drain plugs and customized port layouts meet diverse railway assembly and customization needs.
