Air-suspended centrifugal blower
The air-suspended bearing double-suction high-speed centrifugal blower is a highly efficient, energy-saving, and environmentally friendly product. It features a simple mechanical structure, few moving parts, good control robustness, and easy maintenance. It uses automotive-grade oil-free high-reliability dynamic pressure air bearings, resulting in no friction and minimal mechanical loss during operation. It adopts advanced permanent magnet synchronous motor technology, with a maximum speed of up to 95,000 rpm, and can reach full speed in just 5 seconds.
Core Features and Advantages of Air-Suspended Centrifugal Blowers
I. Core Product Features
1. Energy Saving and High Efficiency, Intelligent Adaptation
The equipment integrates four core components: air bearings, direct-drive technology, high-efficiency impellers, and permanent magnet brushless DC motors, with no additional friction loss during operation. It can automatically match motor power consumption according to the output airflow (adjustable range 40%-100%), maintaining highly efficient operation at all times and significantly reducing energy costs.
2. Low Vibration and Noise, Easy Installation
Relying on air bearings and direct-drive technology, it eliminates vibration at the source, removing the need for additional soundproofing. The equipment is lightweight, requires no dedicated foundation, and is flexible and simple to install, greatly reducing installation difficulty and cost.
3. Oil-Free and Clean, Widely Applicable
Using air bearing technology, the entire system requires no lubricating oil, delivering clean and oil-free air. It is perfectly suited for special industries with strict air quality requirements, such as electronics, pharmaceuticals, and food. The air bearings can withstand temperatures up to 600°C, completely solving issues related to oil contamination and high-temperature failure typical in traditional oil-bearing systems.
4. Maintenance-Free Design, Stable and Worry-Free
By abandoning traditional fan components prone to wear such as gearboxes and oil-bearing systems, the blower employs a direct-drive impeller-to-motor design paired with an intelligent control system. Key components are made from AL7075 aerospace aluminum. Multiple advanced technologies ensure maintenance-free operation, reducing user maintenance costs and significantly enhancing the stability of the air supply system.
5. Intelligent Temperature Control, Flexible Operation
Supports self-checking of fan speed, pressure, temperature, and flow parameters via a personal computer, enabling unattended operation under all conditions, including constant pressure, load/no-load, overload control, and anti-surge control. Flow can be precisely adjusted by modulating the impeller speed, automatically adapting to changes in intake air temperature and pressure, or manually adjusted to meet different operational requirements.
6. Compact and Lightweight, Investment-Saving
The equipment is light, compact, and easy to install, significantly reducing the investment cost for building space planning and auxiliary electrical control systems.
II. Summary of Core Advantages
High Reliability, Easy Maintenance: The core relies on two high-tech technologies, "high-speed direct-drive motors" and "air suspension bearings," eliminating the redundant components required in traditional single-stage high-speed turbo blowers, such as speed-increasing gears, couplings, lubrication systems, and cooling fans. This greatly enhances product performance and operational reliability, completely avoids secondary pollution from noise, vibration, and waste lubricants, and significantly reduces maintenance workload and costs.
