Introduction
The Double Inlet Centrifugal Fan is a type of centrifugal fan designed with two air inlets. This unique design allows the fan to draw air from both sides simultaneously, increasing airflow capacity while maintaining a compact structure.
Features
Stable Airflow
The fan adopts a double-inlet symmetrical structure design, which allows the impeller to inhale airflow from both sides at the same time, reducing the single-sided load and axial thrust, effectively improving the airflow balance and operation stability.
High Ventilation Efficiency
Double Inlet Centrifugal Fan is equipped with a wide-blade backward-inclined impeller, which can efficiently promote large-volume air circulation, with a maximum air volume of 500,000 m³/h, meeting the needs of rapid ventilation in large spaces or high-concentration exhaust in factories.
Flexible Installation
The machine can achieve a large air volume output through a double-inlet structure without increasing the size of the equipment. Under the same air volume conditions, it requires less space than traditional single-inlet fans and can be installed more flexibly in projects with limited space.
Applications
HVAC Systems
Double inlet centrifugal fans are widely used in HVAC systems for efficient air circulation, ventilation, and temperature control.
Air Handling Units (AHUs)
These fans are integral to air handling units, supplying fresh air and maintaining indoor air quality.
Industrial Ventilation
Double inlet centrifugal fans are used in industrial environments for ventilation, dust extraction, and pollution control.
Air Curtains and Air Purifiers
In air curtains, these fans create a strong air barrier that prevents hot or cold air, dust, and insects from entering buildings.
Boilers and Heating Units
Double inlet centrifugal fans supply combustion air in boilers and heating units, ensuring efficient fuel combustion and even heat distribution.

FAQ
Q: Can you provide us sample of centrifuge blower duct fan, is it free or need to pay?
A: A Free sample is always available, freight cost on the customer's side.
Q: What's your payment term?
A: 30% deposit and 70% balance before shipping by LC, TT on FOB terms.
Q: Is there an MOQ for your blower fan?
A: Yes. The MOQ is between 100- 500 pieces for different models after sample approval. And it's also okay for us to accept smaller lots for the initial order.
Q: What is a Double Inlet Centrifugal Fan?
A: A Double Inlet Centrifugal Fan is a type of blower with two air inlets positioned on either side of the impeller, designed to draw air from both sides and discharge it radially. This design enhances airflow and efficiency.
Q: How does a Double Inlet Centrifugal Fan work?
A: Air enters through both inlets, is accelerated by the impeller blades, and is then discharged at a 90-degree angle from the inlet. This setup increases airflow while maintaining compact dimensions.
Q: What are the key features of a Double Inlet Centrifugal Fan?
A: These fans offer high airflow rates, efficient operation, and compact design. They provide stable performance and low noise levels, making them ideal for HVAC and ventilation applications.
Q: What are the common applications of Double Inlet Centrifugal Fans?
A: They are widely used in HVAC systems, air conditioning units, air handling units, ventilation systems, and industrial processes requiring efficient air movement.
Q: What materials are used in Double Inlet Centrifugal Fans?
A: Typical materials include galvanized steel, stainless steel, aluminum, and sometimes plastic for lightweight applications. These materials ensure durability and corrosion resistance.
Q: What are the advantages of using a Double Inlet Centrifugal Fan?
A: They deliver high airflow rates, operate quietly, are compact, and can handle large volumes of air efficiently. The double inlet design maximizes air intake.
Q: What are the limitations of a Double Inlet Centrifugal Fan?
A: They are less suitable for high-pressure applications and can be sensitive to dirt and debris buildup, which can reduce efficiency. Proper filtration is necessary.
Q: How do you select the right Double Inlet Centrifugal Fan?
A: Consider airflow requirements, pressure, noise levels, installation space, and environmental conditions. Check the performance curves to ensure compatibility with the system.
Q: What maintenance is required for Double Inlet Centrifugal Fans?
A: Routine maintenance includes cleaning the impeller and airways, inspecting for wear and tear, lubricating bearings, and ensuring secure motor connections.
Q: Can Double Inlet Centrifugal Fans be controlled for variable speeds?
A: Yes, using variable frequency drives (VFDs) or multi-speed motors allows precise speed control, optimizing airflow and energy efficiency based on demand.
