Comparison between Air-Suspension Fans and Magnetic-Levitation Blowers
In the industrial energy‑saving equipment sector, blowers—key energy‑intensive devices in wastewater treatment, chemical processing, papermaking, and other industries—have long been a focal point of technological advancement. As the “dual carbon” goals gain momentum, conventional Roots blowers are being rapidly replaced by high‑efficiency suspension technologies. Today, air‑suspension blowers and magnetic‑levitation blowers represent the two dominant technological pathways in the market. Both achieve oil‑free, low‑noise, maintenance‑free operation through contactless levitation; however, their underlying principles and application scenarios differ significantly.

There is no inherent superiority between air‑suspension and magnetic‑levitation blowers; the key lies in precise system matching. The essence of equipment selection is neither blindly chasing cutting‑edge technology nor simply minimizing procurement costs, but rather achieving a holistic fit that considers operating conditions, service life, lifecycle costs, and maintenance capabilities. In today’s era of normalized energy conservation and efficiency gains, prioritizing long‑term value and aligning with specific application requirements is the fundamental rationale for selecting a suspended blower.

Driven by both industrial energy‑saving upgrades and the dual carbon goals, traditional Roots blowers and multi‑stage centrifugal blowers are rapidly being phased out, replaced by oil‑free suspended centrifugal blowers—such as those employing air‑bearing and magnetic‑bearing technologies. Both types, with their advantages of contactless operation, oil‑free conveying, low noise, and maintenance‑free operation, have become the preferred choice for energy efficiency in industries including wastewater treatment, chemical processing, food production, and electronics.

Amid the sweeping wave of industrial energy‑saving upgrades, air‑suspension and magnetic‑levitation centrifugal blowers are rapidly replacing traditional Roots blowers and multi‑stage centrifugal blowers, thanks to their shared advantages of oil‑free operation, zero friction, and high efficiency. However, despite both converging under the umbrella term “levitation,” their underlying technological principles are fundamentally different.

From a physical‑mechanism perspective, air‑suspension blowers achieve non‑contact rotor levitation via gas‑film lubrication, thereby eliminating approximately 60% of the mechanical contact noise found in conventional blowers. However, non‑contact does not equate to silence; residual noise primarily originates from three sources: aerodynamic noise, electromagnetic noise, and structural vibration noise.
