The WS7040-24-V200 is a 24V DC brushless blower designed for demanding industrial and portable equipment applications. Key specifications include:

Electrical Characteristics

• Rated Voltage: 24VDC (recommended power supply: 24VDC-4A switching power supply).
• Current Range: 2.8A (fully open airflow) / 0.9A (fully blocked static pressure).
• Hall Sensor Electrical Angle: 60°, enabling precise speed control.

Airflow & Static Pressure

• Free Airflow: 280 LPM (liters per minute) at 36,000 rpm.
• Blocked Static Pressure: 6.5 kPa at 46,000 rpm.

Environmental Adaptability

• Operating Temperature: -20℃ to +50℃ (non-condensing).
• Protection Rating: IP54 (dust and water splash resistant).
• Service Life: L10 lifespan of 10,000 hours under rated load.

Noise & Bearing

• Noise Level: 65 dBA (low-noise optimized design).
• Bearing Type: Japanese NMB ball bearings for extended durability and low friction.

Compact Design with High Output
Ultra-compact form factor (68g weight) ideal for space-constrained portable tools or embedded systems, delivering high static pressure (6.5 kPa) and airflow (25.5m3/h) for efficient thermal management.

Intelligent Speed Control

• Compatible with external drivers (WS2403DY01V04) for PWM or 0–5V analog signal-based stepless speed adjustment, adapting to dynamic cooling requirements.
• Hall sensor provides real-time RPM feedback (1Hz = 60 rpm) for seamless integration with automated control systems.

High Reliability & Durability

• F-class insulation and NMB ball bearings ensure stable operation in high-temperature, high-vibration environments.
• Coil withstands 500VDC/1min voltage, complying with industrial electrical safety standards.

Maintenance & Safety Optimization

• Air intake filter recommended to prolong bearing life.
• Counterclockwise (CCW) rotation direction enhances airflow efficiency and prevents performance degradation from incorrect installation.

Industrial Equipment Cooling

• Welding Systems: Critical for welding machine cooling during prolonged high-load operations.
• Motor Drives & Inverters: Efficient cooling for industrial motor drives, photovoltaic inverters, and high-temperature applications.

Medical & Consumer Electronics

• CPAP Ventilators: Serves as core pneumatic pump component for stable negative pressure airflow (e.g., Haibei CPAP series).
• 3D Printing: Cools print heads to prevent thermal deformation during high-precision manufacturing.

As industrial devices trend toward miniaturization and intelligence, the WS7040-24-V200 emerges as a premium solution for precision thermal management due to its energy efficiency, longevity, and adaptive control. Key selection considerations:

• Power Compatibility: Use 24VDC-4A power supplies to avoid overload risks.
• Environmental Adaptation: Install air filters in dusty environments and perform regular bearing maintenance.
• System Integration: Pair with external drivers for intelligent control and optimal energy efficiency.

Widely adopted in industrial, medical, and transportation sectors, this blower shows potential in emerging markets such as UAV thermal management and LiDAR cooling systems.
