The HGT850-8 is a diesel-driven screw air compressor designed specifically for mobile field operations. It uses a Dongfeng Cummins engine (QSB5.9-C220-30) that meets China III emission standards, and is equipped with a single-stage screw compressor and air-cooled refrigeration system. With a rated air volume of 24 cubic meters per minute and an operating pressure range of 5-10 bar, it can meet the air supply needs of outdoor scenarios such as construction, mining, and continuous emergency repairs. The equipment boasts advantages such as a compact size (4200×1750×2300mm), flexible mobility (4-wheel design), and high air cleanliness (outlet oil content ≤5ppm). It also features a wide operating temperature range of -10℃ to 40℃, providing stable and reliable power support for high-intensity outdoor operations.

Product Introduction

1. Core Advantages of the Product: Tailored for Outdoor Operations

The HGT850-8 Diesel-Driven Mobile Rotary Screw Air Compressor takes "high efficiency, durability, and flexibility" as its core design concepts. Targeting the characteristics of outdoor operations—such as lack of fixed power supply and variable environments—it has been fully optimized in terms of power, compression, heat dissipation, and mobility:
  • Strong Power Guarantee: Equipped with the Cummins QSB5.9-C220-30 National III emission standard engine, it delivers a rated output power of 157kW and can operate at full load for extended periods. The 300L large-capacity fuel tank reduces the frequency of refueling, meeting the needs of continuous outdoor operations.
  • Efficient Compression System: Adopting a single-stage screw compression structure combined with elastic coupling transmission, it operates at a noise level of only 85±3 dB(A). This design not only ensures a large air supply capacity of 24 cubic meters per minute but also minimizes noise interference in the work environment.
  • Adaptability to Complex Environments: The air-cooled heat dissipation design eliminates the need for a fixed water source. It can start at a low temperature of -10℃ (standard configuration) and operate stably at a high temperature of 40℃. Meanwhile, the 4-wheel mobile structure allows flexible on-site position adjustment, making it suitable for multiple scenarios such as construction sites, mines, and field emergency repairs.

2. Key Performance: Balancing Air Volume, Pressure, and Air Quality

In terms of core air supply performance, the HGT850-8 is strictly tailored to the working conditions of outdoor pneumatic tools (e.g., breakers, jackhammers, pneumatic wrenches):
  • Air Volume and Pressure Adaptability: With a rated air volume of 24 cubic meters per minute, it can drive multiple pneumatic devices simultaneously. The working pressure range is 5-10 bar, which can be adjusted according to tool requirements. The minimum air tank pressure is 4 bar and the maximum unloading pressure is 10 bar, preventing pressure fluctuations from affecting work efficiency.
  • Clean Air Output: The oil content at the compressed air outlet is ≤5 ppm, meeting industrial-grade clean air standards. This effectively prevents oil contamination from clogging internal components of pneumatic tools, extending tool service life and reducing maintenance costs.
  • Stable Operation Guarantee: The screw lubricating oil capacity is 80L (to be replaced per maintenance cycle), which, combined with the engine’s 24L lubricating oil capacity, forms a comprehensive lubrication protection system. This reduces mechanical wear and enhances equipment durability.

3. Application Scenarios: Covering Various High-Intensity Outdoor Operations

With its excellent outdoor adaptability and air supply capability, the HGT850-8 is widely used in the following scenarios:
  • Construction: Provides continuous air supply for equipment such as concrete breakers, road cutters, and pile driving machinery.
  • Mining: Adapts to equipment like rock drills and pneumatic loaders in open-pit mines, meeting the needs of high-intensity mining operations.
  • Emergency Maintenance: Serves as a temporary air supply source for pipeline repairs and equipment troubleshooting in remote areas.
  • Field Engineering: Supports projects without fixed power facilities, such as road construction and bridge building, ensuring the normal operation of pneumatic tools.
