Power. Precision. Proven Hertz Reliability.

The Hertz Kompressoren HDD 30 – 40 HP rotary screw air compressor is designed for businesses that need dependable compressed air without compromise. This oil-injected, direct-drive system delivers exceptional energy efficiency, low operating noise, and industrial-grade reliability — all backed by Hertz’s legendary engineering and innovation.

Efficient Performance You Can Trust

The HDD 30 Series delivers up to 207 CFM @ 100 PSI, providing smooth, consistent airflow for demanding industrial and manufacturing applications. The direct-coupled IE4 IP55 motor eliminates belt losses, reducing maintenance costs while maximizing efficiency and longevity.

Smart Cooling and Rugged Durability

Featuring independent radiator segments and a low-speed radial cooling fan, this compressor keeps internal temperatures low and stable — even in harsh environments up to 113°F ambient. A precision-machined screw block with next-generation rotor profiles ensures reduced torque requirements, quieter operation, and long-term reliability.

Intelligent Control System

Equipped with a user-friendly controller, the HDD 30 allows real-time monitoring of operating conditions, load/unload cycles, and maintenance intervals. It supports ModBus communication and Master/Slave synchronization for two-compressor systems, making it a perfect choice for multi-unit installations or expanding facilities.

Simplified Maintenance

Removable hinged panels and a hinged oil tank cover provide fast, easy service access. The quick-service coupling system enables maintenance on the drive assembly in under 30 minutes — minimizing downtime and keeping your operation running at peak efficiency.
