Product Introduction
The air-bearing, double-suction high-speed centrifugal blower is an efficient, energy-saving, and environmentally friendly product. It features a simple mechanical design with few moving parts, offering excellent control robustness and ease of maintenance. Equipped with automotive-grade, oil-free, highly reliable hydrodynamic air bearings, the unit operates with zero friction and minimal mechanical losses. Powered by advanced permanent-magnet synchronous motor technology, this blower can achieve speeds of up to 200,000 rpm, reaching full speed in just 5 seconds. The motor boasts an impressive efficiency of up to 97%, meeting the stringent dual-level Tier 1 energy efficiency standards. Additionally, the blower incorporates a wide-range, high-efficiency three-dimensional impeller that overcomes key technical challenges associated with low specific speed designs, ensuring exceptional performance. The integrated, specialized design of the main unit ensures noise levels remain below 75 dB(A) and vibration is kept to less than 12 μm. With its stepless adjustment capability, the blower enables rapid start-and-stop operations, supporting continuous on/off cycles exceeding 200,000 times without degradation.
Product Features
Our air-bearing blowers feature long lifespan, compact size, oil-free operation, energy efficiency, easy maintenance, cloud-based intelligent control, and low noise—among other key advantages.
Long-lasting, low-noise
The bearings are frictionless, and the design life of the core components is greater than 20 years.There is no mechanical vibration and the noise is less than 85 decibels.
Small in size
The integrated design has a large power density, which is 1/3-1/5 of the volume of traditional blowers. It is simple to install and can be placed directly without foundation.
Oil-free and environmentally friendly
The use of advanced air bearings, no friction, no need to refuel and lubricate
Cloud smart management
User mobile and PC cloud management, real-time return of operating data, interconnection with the customer's central control system, easy to provide timely analysis and services.
Easy to maintain
Only need to clean the filter cotton regularly according to the system prompts.
High-efficiency and energy-saving
Integrated high-speed permanent magnet synchronous motor, high-efficiency centrifugal impeller, air bearing, and adjust the operating state of the blower according to the load, which can save 20%-50% compared with traditional fans.
