BISON®'s ROTRON® CP and EN Regenerative Blowers set a new standard for biogas applications, delivering superior safety, performance, reliability, and noise reduction compared to rotary lobe technology

KENT, OHIO - Bison®, a leader in innovative air-moving technologies and a strong advocate for advancing renewable energy production, will showcase its cutting-edge ROTRON® Chemical Processing (CP) and Environmental (EN) Regenerative Blowers at Biogas Americas 2025, April 28-30, at the Colorado Convention Center in Denver. As part of its commitment to sustainable energy solutions, Bison® invites visitors to booth #1008 to experience firsthand how robust and versatile regenerative blower technology is revolutionizing biogas collection and movement in agricultural and environmental applications.

Regenerative blower technology offers a simple yet sophisticated design, providing a compact, non-contact solution that outperforms traditional positive displacement rotary lobe blowers in biogas digester applications. These benefits include improved safety, reliable and consistent performance, exceptional durability, and quieter operation.

1. Safety: By eliminating metal-to-metal contact—a common problem with rotary lobe blowers--the risk of sparking is minimized, which is crucial when handling highly flammable biogas, thus preventing combustion and explosion.

2. Consistent Performance: Regenerative blowers excel at maintaining steady flow rates despite fluctuating system conditions, a critical feature for anaerobic digesters where stable pressure is essential.

3. Durability and Longevity: The non-contact design enhances resilience against particulates commonly found in biogas, which can cause wear in other blower designs. Such durability is vital for maintaining efficiency and extending the equipment's lifespan.

4. Compact Size: The highly efficient regenerative action enables each rotation to generate pressures or vacuums comparable to those produced by significantly larger multi-stage or positive displacement blowers.

5. Low Maintenance: With fewer components, regenerative blowers are not only more durable but also easier to maintain - with no need for oil or filter replacements, they are virtually maintenance-free.
