Hertz HGS 4 Fixed Speed Compressor

Meet the Hertz HGS 4 Fixed-Speed Rotary Screw Air Compressor—a compact, oil-injected unit built for reliable performance in small to mid-sized workshops. Powered by a 4 kW fixed-speed motor (5.5 hp) and paired with an energy-efficient IE3 drive, it delivers consistent air while helping to reduce operating costs. Its compact screw block provides durable, efficient airflow with minimal wear, and quiet operation at 67 dB(A) keeps noise-sensitive environments comfortable. Configure it to fit your space with base-mounted, tank-mounted, or tank-mounted with dryer options, designed for easy installation in tight areas. Advanced cooling is handled by an aluminum combi-cooler and a dry-type intake filter, maintaining reliable performance up to 45°C with minimal maintenance. Maintenance is straightforward thanks to an electropneumatic suction valve, full-flow oil filter, and a user-friendly PLC control unit. Flexible pressure options of 110, 125, or 145 psi enable free air delivery from 10.2 to 19.2 cfm depending on pressure. Backed by a 5-year warranty, the Hertz HGS 4 is engineered for continuous operation in busy shops.
