RailMac BT-2.6/10AZ2

The BT-2.6/10AZ2 air compressor is a specialized power equipment designed exclusively for Dongfeng series diesel locomotives. Adopting electric motor drive, direct-drive structure and air-cooled heat dissipation, it features a rated power of 24kW, rated discharge pressure of 1000kPa, and nominal volume flow rate of 2.6m³/min. Capable of continuous and stable operation in extreme ambient temperatures ranging from -40°C to 55°C, it provides a reliable air source guarantee for locomotive braking systems and other pneumatic devices.

Advantages of BT-2.6/10AZ2

The direct-drive transmission minimizes energy loss, boosting efficiency and stability. With 24kW rated power and 2.6m³/min flow rate, it quickly maintains 1000kPa pressure, meeting locomotive pneumatic systems’ instantaneous and continuous air demands. The S1 duty cycle supports 24/7 uninterrupted operation, matching locomotives’ long-term operation requirements.
Operating in -40°C to 55°C temperatures, it performs reliably in extreme climates for diverse regional railway operations. The air-cooled structure eliminates water reliance, simplifying maintenance. Custom-built for Dongfeng series locomotives, it features high integration and perfect compatibility with installation spaces and pneumatic interfaces.
The direct-drive structure reduces vulnerable components, lowering failure rates and extending service life. The air-cooled system cuts operational costs by eliminating waterway maintenance. Its stable full-condition operation ensures safe air supply for critical systems like braking, minimizing locomotive outage risks.
Combining direct-drive and air-cooling, it has a compact footprint for easy installation in limited locomotive engine compartments. The low-noise motor drive creates a comfortable working environment and reduces electronic interference. Compliant with strict railway standards, it offers excellent shock resistance and durability against operational vibrations.
