Bison® Showcases Regenerative Blower Solutions Designed to “Moooove” Biogas More Efficiently, Quietly, and Safely
KENT, OHIO — Bison a leader in innovative air‑moving technologies and an advocate for renewable energy infrastructure, will showcase its ROTRON® Chemical Processing (CP) and Environmental (EN) Regenerative Blowers at Biogas Americas 2026, taking place May 18–20 in Detroit, Michigan, at booth #452.Bison will feature its “Mooooving Biogas?” theme, a nod to agricultural biogas systems where methane generated from livestock manure—commonly from cows—is captured and moved through digester and renewable natural gas infrastructure.
As biogas digester projects continue to expand across agricultural and environmental applications, regenerative blower technology is gaining wider adoption as an effective alternative to traditional positive displacement rotary lobe blowers. The simple, compact, and non‑contacting design of regenerative blowers provides important advantages in safety, reliability, maintenance, and noise reduction—factors that are increasingly critical in modern biogas systems.
Improved Wear, Noise, and Safety with Regenerative Blowers vs. Positive Displacement Technology
Positive displacement rotary lobe blowers rely on tight metal‑to‑metal clearances to move gas, which can introduce wear, noise, and increased ignition risk when handling corrosive and highly combustible biogas.In contrast, regenerative blowers operate without internal contact, reducing mechanical wear and helping support safer operation while maintaining consistent airflow.
For biogas digesters, stable pressure and flow are essential to support anaerobic digestion and downstream gas handling. Regenerative blower technology is well suited for these requirements, particularly in systems that experience fluctuating operating conditions.
Supporting Safer and More Efficient Biogas Systems
Within biogas infrastructure, blowers play a critical role in transferring gas from digesters to compression, processing, and renewable natural gas (RNG) systems. Regenerative blowers provide dependable performance while offering additional benefits that support efficient system design, including lower operating noise, compact installation, and minimal maintenance requirements.“As more agricultural operations adopt biogas digesters, system reliability and operational consistency become critical,” says Neil Lynch, Senior Applications Engineer for Bison. “Choosing the right blower technology early in the design process can have a long‑term impact on safety, uptime, and overall system performance.”
Long‑Life Performance and Built for Demanding Applications
Bison’s ROTRON CP and EN Regenerative Blowers are designed and manufactured in the United States at an ISO‑9001‑certified facility in Whitsett, North Carolina. Built specifically for demanding biogas applications, these blowers feature corrosion‑resistant aluminum construction, advanced sealing options to reduce leakage, explosion‑proof motor selections for hazardous environments, and long service life exceeding 25,000 hours.These attributes help biogas system designers balance safety, performance, durability, and total cost of ownership.
