11kW Permanent Magnet Variable Frequency Screw Air Compressor
Products Description
The 11kW permanent magnet variable-frequency screw air compressor is a high-efficiency, energy-saving air supply unit designed specifically for small-to-medium-sized fiber laser cutting machines and industrial pneumatic systems. Equipped with a high-efficiency permanent magnet motor and precision screw rotors, the unit offers stable operation, low noise levels, and exceptional durability. It is perfectly suited for 3000W–4000W laser cutting equipment, fully meeting the rigorous air supply requirements of applications such as metal cutting and engraving.

Featuring an all-in-one integrated design, the unit combines air storage, drying, and precision filtration functions. It effectively removes moisture, oil, and impurities from the compressed air, delivering a clean, dry air supply that prevents issues such as laser lens contamination, nozzle clogging, and cutting surface defects. This significantly enhances workpiece quality while reducing equipment failure rates and maintenance costs. Utilizing intelligent variable-frequency control technology, the compressor automatically adjusts output based on actual air demand to minimize no-load energy loss, achieving energy savings of over 30% compared to traditional fixed-speed equipment.
Technical Specifications
The equipment features a compact design with a small footprint and offers easy, plug-and-play installation, making it widely applicable across industries such as sheet metal processing, hardware manufacturing, and signage production. Compliant with CE and ISO international standards, the product is suitable for export to global markets, including Southeast Asia, the Middle East, and Europe. Thanks to its stable performance, exceptional service life, and convenient after-sales maintenance, it has become the preferred gas supply solution for small and medium-sized laser processing enterprises both at home and abroad.
