In our previous article, we introduced Liugong Air Compressors, backed by the Chinese state-owned enterprise Liugong. Today, we’ll take a look at their product lineup and how to select the right model for your project.
When requesting quotes from us, some customers provide a specific model number, while others know the pressure or air volume they need. However, many have no understanding of air compressor specifications or their suitable applications. This requires distributors or manufacturers to have a thorough understanding of the products they sell or develop, as well as years of industry experience, so they are fully versed in the practical applications of air compressors.
First, let’s take a look at the product lineup for Liugong Air Compressors:

Based on the figure above, you can determine the pressure and air flow rate of the air compressor according to the target bore diameter and depth specified in your project brief, and select the appropriate air compressor model. For example, if the target depth is w × 100 m, based on our many years of industry experience, you can choose a w × 10 bar air compressor. Provided the specifications are accurate, this air compressor can generally drill a hole with a diameter of 203 mm and a depth of w × 100 m. If the bore diameter is larger, the depth will be less than w*100m; if the bore diameter is smaller, the depth will be greater than w*100m.
In addition to these two parameters, you can also select the engine type, emission class, whether the unit is skid-mounted, and whether it features variable-frequency starting, among other options.
If you are new to the industry and have not yet received a project or project brief, you can select a suitable model based on the model recommendations we have summarized for different application scenarios:

Electric Screw Air Compressor Solutions for Mining OperationsIntelligent Interlocking: Enables simultaneous interlocked control of multiple air compressors; interlocking modes can be configured according to user needs.
Energy Conservation and Emissions Reduction: Optional variable frequency drives (VFDs) control motor speed based on actual air consumption, intelligently adjusting to the most energy-efficient operating plan.
Lower Costs: Low operating and maintenance costs, with a longer service life. Efficient and Convenient: Plug-and-play containerized air compressor stations offer relatively low total procurement costs. Installation requires only a level site; the unit is easy to hoist into place, convenient to transport, and causes virtually no environmental impact.
Centralized Air Supply Solution: Multiple air compressors operate in parallel to provide centralized air supply, which is then distributed to individual air outlets. This effectively reduces operating costs and improves operational efficiency.
