High air output for demanding applications
Designed for applications with high compressed air demand, the range delivers continuous airflow to support intensive daily operations. Whether used for large infrastructure projects, mining activities, geothermal drilling or industrial processes, it provides the performance needed to keep work progressing efficiently.The electric drive system combines strong output with low noise levels and zero on-site exhaust emissions, helping support both productivity and environmental objectives.
Heavy duty mobility for smooth site transfer
This range is built with a heavy duty reinforced structure, balancing large air supply capacity and reliable mobility. Compared with the lighter weight wheels of small-sized range and the regular load capacity of medium sized models, the large range has a significantly improved load bearing capacity and is suitable for towing and transfer by large vehicles. It can handle complex road conditions such as remote outdoor construction sites, rugged mountain roads and muddy sites that are difficult for small and medium sized models to pass and also enables flexible movement within the construction site.
Extended service intervals for maximum uptime
Designed for demanding, high‑duty applications, this large mobile air range features an optimized powertrain and heavy‑duty components that enable significantly extended service intervals. Compared to smaller and mid‑range units, maintenance is required less frequently, reducing planned downtime and minimizing interruptions to ongoing operations. This results in higher overall uptime, smoother project execution, and lower operational overhead. This is especially critical on large‑scale infrastructure, mining, and remote construction sites where access to service support can be limited.
