Introduction
Direct Drive Fan is a ventilation device in which the motor is directly mounted on the fan shaft. The fan speed is determined by the motor's RPM, offering simple and efficient operation.
Features
High-efficiency Direct Drive System
The Direct Drive Fan use permanent magnet synchronous motor direct drive technology, with a transmission efficiency of 98%, which is 15-20% more energy-efficient than traditional belt drive systems.
Accurate Speed Control Capability
Our products are equipped with a variable frequency speed regulation system, with a speed control accuracy of ±1 RPM. Through a closed-loop control system, the air volume can be precisely adjusted within a pressure range of 500-25000Pa, with a response time of less than 0.5 seconds, which is 3 times faster than a mechanical speed regulation system.
Wide Temperature Range Stability
Our products use a high-temperature resistant motor design, with an insulation grade of H (180°C), and with a 0-200mm adjustable insulation layer, they can operate continuously at ambient temperatures of 20°C to 600°C.
Applications
Building and Commercial Building HVAC System
Widely used in air handling units (AHU), duct supply and exhaust systems, fan coils and other equipment in central air conditioning systems.
Data Center Cooling System
Used in cold aisles, hot aisles, and inter-row cooling equipment to ensure constant temperature operation of server equipment.
Medical Institutions and Negative Pressure Wards
In hospital operating rooms, negative pressure wards, isolation areas and other places, direct-drive fans can provide a stable negative pressure environment to ensure safe airflow control and prevent cross infection.

FAQ
Q: What is a direct drive fan and how does it work?
A: A direct drive fan connects the fan blades directly to the motor shaft without belts or pulleys. The motor's rotation directly drives the fan, resulting in a more compact design and fewer mechanical parts.
Q: What are the advantages of a direct drive fan?
A: Direct drive fans offer lower maintenance, improved energy efficiency, quieter operation, and compact size. Since there are no belts to adjust or replace, they are ideal for continuous operation with minimal service needs.
Q: Where are direct drive fans commonly used?
A: They are widely used in HVAC systems, cleanrooms, laboratories, small spray booths, and air handling units. They're suitable for applications requiring reliable, low-maintenance airflow with moderate static pressure.
Q: How does a direct drive fan compare to a belt drive fan?
A: Direct drive fans are more efficient and require less maintenance but offer limited flexibility in speed control. Belt drive fans allow for adjustable fan speeds and higher static pressure capabilities, making them better for large-scale or variable airflow systems.
Q: What should you consider when selecting a direct drive fan?
A: Consider airflow rate (CFM), static pressure, motor power, voltage, noise level, and space constraints. Also, ensure the fan is suitable for the air type-whether clean, dusty, or corrosive-based on the application environment.
