Hertz HGS 5.5 Fixed Speed Compressor

Introducing the Hertz HGS 5.5 Fixed-Speed Rotary Screw Air Compressor, a compact, oil-injected workhorse designed for reliability in small to mid-size shops. This 5.5 kW fixed-speed model of the HGS series pairs an energy-efficient IE3 motor with a durable screw block to deliver steady, high-quality compressed air for automotive bays, workshops, and light manufacturing. At only 67 dB(A), it keeps noise to a minimum in noise-sensitive environments. Choose from base-mounted, tank-mounted, or tank-mounted with dryer configurations to fit your space and workflow. Advanced cooling and filtration—an aluminum combi-cooler and a dry-type air intake filter—support reliable operation up to 45°C with minimal maintenance. Maintenance is straightforward thanks to an electropneumatic suction valve, full-flow oil filter, and a simple PLC control unit. Pressure options include 110, 125, or 145 PSI, with free air delivery of 14.5–25.2 CFM depending on pressure. Backed by a 5-year warranty (Ts & Cs apply).
