This is our two-stage screw air compressor, model SAD132 (132KW 175HP), with a power output of 132KW and an outlet size of DN65. It features two-stage compression capability, making it suitable for various industries with different air pressure requirements. The two-stage refers to the compression method, and the screw machine is the main type, with a core structure of dual-screw rotors. The rotors undergo 20 precision-machined processes, ensuring the accuracy, reliability, and effectiveness of meshing compression. The discharge capacity of this model is 175HP, indicating stronger motor power, making it ideal for users with high air production requirements.
In harsh environments such as high temperatures and high altitudes, these conditions can reduce motor efficiency. However, it is still necessary to maintain sufficient gas production capacity, often requiring the use of a higher HP machine to match the environment. For instance, in applications like high-pressure pipeline transportation or precision high-pressure pneumatic equipment, where stable high-pressure gas output is required without tolerating pressure fluctuations, selecting this 175HP air compressor is an optimal choice.
Then you might also wonder, compared to single-stage and other models, which one is better—the two-stage air compressor, and how to choose? We recommend selecting based on your needs. For example, if you are a small or medium-sized factory or an individual business owner, and your usage scenario involves light loads (≤1.2MPa) and low-pressure applications, while also wanting to avoid high upfront procurement costs and potential future maintenance expenses, a single-stage compressor would suffice, as it reduces procurement costs and meets basic requirements. Conversely, if you are a larger-scale business owner, and the air compressor operates under heavy loads (≥1.5MPa) and high-pressure scenarios, a two-stage model would be the better choice, as it ensures energy efficiency and delivers stable performance.
