Screw Air Compressor Pump for High-Speed Train (EMU/HST) Braking, Suspension and Auxiliary Pneumatic Systems Overview This screw air compressor pump is purpose-built for high-speed train (EMU/HST) braking, suspension and auxiliary pneumatic systems, integrating a high-efficiency screw main unit into a compact, lightweight package. It delivers stable, clean, oil-free (or oil-injected, per system design) compressed air to keep braking, door, pantograph and suspension components operating reliably during continuous high-speed operation. Engineered for low noise, low vibration and long service intervals, it meets the strict reliability and safety demands of railway applications. Core Features • High-Efficiency Screw Airend: optimized rotor profile ensures high volumetric efficiency, stable output pressure and low energy consumption. • Rail-Specific Compact Design: integrated structure saves space and weight — critical for underframe and equipment-room installation. • Clean Air Delivery: oil-free or oil-separated options available to protect sensitive pneumatic components and brake systems. • Low Noise & Vibration: precision balancing and acoustic insulation make it suitable for passenger comfort and urban/night service. • Durable & Low Maintenance: wear-resistant construction, extended oil service life and easy filter/oil change reduce lifecycle cost. • Wide Operating Range: performs reliably across extreme temperatures, altitude and high-humidity environments. Technical Specifications (Typical) Item Specification Application High-speed train braking, air suspension, door control, pantograph & auxiliary pneumatics Flow Capacity 0.3 ~ 3.0 m³/min (customizable) Working Pressure 0.8 ~ 1.3 MPa (adjustable) Compression Type Oil-injected / Dry oil-free screw (optional) Power Rating 5.5 ~ 37 kW (AC 380/440 V, 50/60 Hz or DC power) Speed Range 1500 ~ 3000 rpm Cooling Method Air cooling / Water cooling Noise Level ≤ 72 dB(A) (at 1 m) Protection Grade IP54 / IP55 Lubrication Special railway-grade oil, long-life design Mounting Type Direct flange mounting / Flexible coupling Dimensions & Weight Customized per train model and space envelope Benefits • Ensures consistent air supply for critical braking and suspension safety functions. • Reduces downtime with extended maintenance intervals and high reliability. • Lightweight and space-saving design maximizes train payload and interior layout flexibility. • Low noise and vibration improve passenger comfort and meet railway noise regulations. • Long service life and proven durability reduce total cost of ownership. Application Scenarios • High-speed trains (EMU, DMU, HSR) • Urban rail / metro / light rail vehicles • Special pneumatic systems on locomotives and coaches • Braking, air suspension, door, pantograph and whistle systems Why Choose Us?

skid-mounted screw air compressor pump for mining and drilling rigs This vehicle-mounted screw air compressor pump is designed for mining and drilling rigs, integrating a high-efficiency screw airend into a compact, skid-mounted chassis. It delivers continuous, reliable compressed air at the well site, eliminating the need for a separate stationary compressor and greatly improving rig mobility and operating efficiency. Ideal for blast hole drilling, water well drilling, geothermal drilling, and construction piling applications.

The GCU55 integrated compressor unit is an all‑in‑one assembled screw compressor host integrating air‑end, drive motor, dual oil‑gas separators, oil filter, intake valve and complete oil circulation piping system. This highly integrated unit eliminates complicated motor‑host alignment work for compressor OEMs. Constructed with heavy‑duty cast‑iron pressure vessel housing and high‑efficiency rotor profile, it delivers large stable air flow. Spin‑on filter cartridges enable quick maintenance. It is perfect for new compressor manufacturing, host replacement and equipment retrofitting projects for medium‑large industrial compressed‑air systems.

The K10 integrated screw air‑end is a compact pre‑assembled screw compressor host. It integrates rotor assembly, spin‑on oil‑gas separator, oil filter, intake valve, solenoid valve and built‑in oil circuit components into one single unit. This all‑in‑one design greatly simplifies compressor OEM assembly work. Made of high‑strength cast iron housing and high‑precision screw rotors, it offers stable air output, compact footprint and easy maintenance. It is widely used for small‑to‑medium screw compressor manufacturing, air‑end replacement and aftermarket overhaul projects.
