WS145140-48-170-S300: High-Performance 48VDC Brushless DC Blower with High Airflow & High Static Pressure

In industrial air-moving applications-including equipment cooling, ventilation, air supply, and purification systems-demanding working conditions require components that deliver high airflow, powerful static pressure, and long-term reliability.

Wonsmart (Ningbo Wonsmart Motor Fan Co., Ltd.) introduces the WS145140-48-170-S300, a premium brushless DC blower engineered for high-load, high-standard environments. This model combines superior airflow, ultra-high wind pressure, and excellent environmental adaptability, making it a trusted air-moving solution for industrial manufacturers worldwide.

Powered by a 48VDC high-efficiency brushless three-phase motor, the WS145140-48-170-S300 balances rotational speed, airflow, and pressure across three typical operating conditions-outperforming standard blowers in its class.

• Speed: 18,000 RPM (±5%)
• Airflow: 95 m³/h (±10%)
• Current: 14.5A (±10%)

When the air outlet is fully open, the blower rapidly delivers large air volumes for efficient heat dissipation and rapid ventilation-ideal for open-space air circulation and overall equipment cooling.

• Speed: 14,500 RPM (±5%)
• Static Pressure: 86 kPa (±10%)
• Current: 58A (±10%)

Peak static pressure enables the blower to overcome resistance from dense pipelines, filter screens, and complex confined spaces-solving air supply challenges in high-resistance environments.

• Speed: 16,600 RPM (±3%)
• Static Pressure: 42 kPa
• Airflow: 57 m³/h
• Current: 38.5A (±10%)

Under standard daily operation, the blower maintains consistent, efficient air output-avoiding performance fluctuations caused by load changes and reducing equipment failures.

The WS145140-48-170-S300 features a mature integrated design with standardized dimensional tolerances for key inlet and outlet components, simplifying installation and enabling embedded assembly in various devices.

Wiring (200mm three-wire scheme):

• Pin 1 (Yellow) – Phase U
• Pin 2 (Blue) – Phase V
• Pin 3 (White) – Phase W

The intuitive wiring sequence reduces assembly errors and lowers the user's installation threshold.

Driver Compatibility:
The blower works seamlessly with Wonsmart's dedicated WS4860ZX01V01 driver. The matching drive system supports precise PWM speed regulation, allowing flexible adjustment of speed, airflow, and pressure based on real-world needs-reducing unnecessary power consumption and improving overall energy efficiency.

Built for harsh operating conditions, this blower offers exceptional temperature and humidity resistance.

Whether in high-temperature industrial workshops, low-temperature cold storage, or humid enclosed spaces, the blower maintains stable performance without aging damage or parameter degradation..

Thanks to its dual strengths of high airflow and ultra-high static pressure, the WS145140-48-170-S300 serves multiple industries:

• Industrial equipment centralized cooling
• Medical ventilation equipment
• New energy fuel cell air supply
• Intelligent dust removal systems
• Automatic cleaning equipment
• Duct pressurization and high-resistance air supply

Compared to conventional blowers, it offers stronger environmental interference resistance, higher working efficiency, and longer service life.

Wonsmart specializes in the R&D and production of high-performance DC blowers, with extensive experience in air-moving component design and manufacturing. Each WS145140-48-170-S300 blower undergoes strict factory testing on speed, pressure, airflow, and durability-ensuring every delivered unit meets high-quality standards.

If you need a high-efficiency, stable, and cost-effective high-pressure, high-airflow blower to upgrade your equipment performance, the WS145140-48-170-S300 is the optimal choice.
