Direct Drive Delta Hybrid Blowers For Energy-Efficient Wastewater Aeration: AERZEN On The Water Online Show

Aeration can represent 50% to 60% of a municipal wastewater treatment plant’s operating costs, making blower efficiency a significant opportunity for savings.

Aerzen’s Delta Hybrid direct-drive screw blower combines the broad operating range of positive displacement technology with high energy efficiency, while design improvements address real-world considerations such as turndown, footprint, maintenance, and future capacity needs. An independently driven oil pump enables turndown of up to 5:1, helping plants better match airflow to changing demand and avoid unnecessary power consumption. New larger sizes, including the D120 at approximately 4,000 CFM, extend these advantages to higher-flow applications.

Learn how direct-drive hybrid technology can help utilities balance energy efficiency, process flexibility, serviceability, and long-term infrastructure planning.
