The WS9070-24-S300 air blower, developed by Ningbo Wonsmart Electromechanical Co., Ltd., is a three-phase brushless DC centrifugal blower engineered for high-performance applications requiring stable airflow and pressure. Featuring Japanese NMB ball bearings and Class F insulation, this blower combines a compact 1.5kg design with robust construction, achieving an IP51 protection rating and operating temperature range of -20°C to 50°C.
With optimized motor design—including 1 pair of rotor poles, phase resistance of 0.56~0.62Ω, and phase inductance of 0.40~0.46mH—the WS9070-24-S300 balances energy efficiency and low electromagnetic interference. This makes it ideal for precision equipment where reliability and minimal noise (80dBA) are critical.
Core Parameters
| Condition | Speed (rpm) | Pressure (kPa) | Airflow (L/min) | Current (A) |
|---|---|---|---|---|
| Fully Open | 28,000 | - | 115 | 1.4 |
| Fully Closed | 26,000 | 13.5 | - | 2.5 |
Key Features
- Longevity: 10,000 hours of continuous operation at 40°C (NMB bearing technology).
- Certifications: ETL, CE-EMC, RoHS, and REACH compliant.
- Power Requirement: 24VDC 8A switching power supply recommended for stable performance.
- Mechanical Design: Sealed structure minimizes air leakage and ensures consistent airflow under varying loads.
Fuel Cell Systems
The WS9070-24-S300 delivers 13.5kPa maximum pressure to optimize oxygen diffusion in fuel cell stacks, enhancing energy conversion efficiency by 5%–8%. Its -20°C cold-start capability suits both automotive and stationary power generation applications, ensuring reliable operation in harsh environments.
Medical Equipment
With ±1% speed control precision, the blower enables accurate airflow adjustment (0.1L/min increments), meeting strict requirements for ventilators and anesthesia machines. The IP51 rating prevents dust and liquid ingress, critical for maintaining sterility in healthcare settings.
Industrial Automation
In soldering equipment and buffer air cushion machines, the blower’s high rotational speed (28,000rpm) supports rapid heat dissipation and efficient air inflation. Customizable impeller designs and control algorithms allow adaptation to specific industrial workflows.
Founded in 2009, Ningbo Wonsmart specializes in miniature brushless motors and blowers, with annual growth of 30%. The company’s 60% export share spans North America, Europe, Japan, and South Korea, supported by ISO 9001 quality management and in-house testing facilities (e.g., automatic winding machines, dynamometers).
Wonsmart’s products, including the WS9070-24-S300 air blower, comply with global standards (ETL, CE-EMC, RoHS) and serve clients like Philips and Siemens.
With 20+ core patents, the company continues to innovate in high-efficiency, long-life blower technology.
