Introduction
Backward Curved Plug Fan is a highly efficient and energy-saving centrifugal fan with a backward curved impeller design.
Features
High Efficiency
The Backward Curved Plug Fan uses an advanced electromagnetic winding structure and a high-efficiency motor constructed with low iron loss silicon steel sheets. The overall energy efficiency is as high as 92%, which can save about 30% of the operating power cost compared to traditional fan systems.
Easy Installation
The backward curved fan adopts a plug-in structure, which supports flexible docking in multiple directions (horizontal or vertical), and reserves standard mounting holes and quick-connect interfaces, which can be quickly docked with the ventilation system without the need for additional brackets or structural modifications.
Good Stability
The backward-curved structure of the fan reduces internal airflow turbulence and reduces operating vibration, which is suitable for application scenarios with high requirements for airflow uniformity.
Low Noise
The machine uses a backward curved impeller, the tail end of which is tilted in the opposite direction of rotation, which optimizes the airflow introduction path, reduces impeller impact and turbulence, and reduces operating noise by about 3~5 dB compared to traditional forward impeller fans.
Applications
- Hot air delivery for industrial furnaces: supports stable hot air delivery under high temperature conditions to ensure production continuity.
- Ventilation and ventilation system: suitable for air circulation and ventilation in factories, warehouses and other places to improve the quality of ambient air.
- Dust removal equipment: cooperate with dust collectors to efficiently remove dust and protect the health of equipment and operators.
- Clean workshop ventilation: provides low noise and stable air volume to meet cleanliness control requirements.
- Air conditioning and refrigeration system: Backward Curved Plug Fan can achieve uniform air delivery and improve the overall efficiency of the system.
- Other industrial gas delivery: applicable to gas delivery and emission needs in various industrial processes.

FAQ
Q: What information do you need to provide when inquiring?
A: Air volume, air pressure, and whether there are heat resistance requirements, explosion-proof requirements, anti-corrosion requirements or other requirements.
Q: What is the working principle of the backward curved plug fan?
A: The backward curved plug fan drives the impeller to rotate through the motor. The backward curved blades of the impeller give the air centrifugal force, flow along the volute and be discharged, and at the same time, the central area forms a negative pressure to inhale new air.
Q: What are the requirements for the installation position of the backward curved plug fan?
A: The backward curved plug fan should be installed in a place where the air flow is smooth, away from obstacles, and ensure that the air inlet and outlet are unobstructed, so as to effectively inhale and exhaust air and improve ventilation efficiency.
Q: What is the relationship between the wind pressure and air volume of the backward curved plug fan?
A: Within a certain range, the wind pressure of the backward curved plug fan increases and the air volume will decrease. Because the increase in wind pressure means that the air flow resistance becomes larger, resulting in a decrease in the amount of air passing through the fan per unit time.
Q: How to judge whether the motor of the backward curved plug fan is damaged?
A: If the backward curved plug fan does not run and there is no obvious mechanical failure, the motor does not hum after power is turned on, or the motor housing is overheated and has a strange smell, it may be that the motor is damaged and needs further inspection.
Q: Does the backward curved plug fan need to be debugged after installation?
A: It needs to be debugged. Debugging can ensure that the backward curved plug fan operates normally, check whether the air volume and air pressure meet the requirements, and whether the fan has abnormal vibration and noise, and adjust it in time to achieve the best operating state.
Q: How should the backward curved plug fan be stored if it is not used for a long time?
A: The backward curved plug fan should be cleaned and placed in a dry, ventilated environment without corrosive gases. The fan can be disassembled into components for storage, and the key parts can be wrapped with protective covers to prevent dust and moisture erosion.
Q: When can I get the quotation?
A: We usually quote within 24 hours after we get your inquiry. If you are urgent to get the price, please send the message on trade management or call us directly.
Q: Do you accept OEM manufacturing?
A: Yes! We do accept OEM manufacturing. You could give us your samples or drawings.
Q: How to control the products quality in your company?
A: With professional quality team, advanced product quality planning, strict implementation, continuous improvement, the quality of our products is well controlled and consistent.
Q: Can you provide detailed technical data and drawing?
A: Yes, we can. Please tell us which product you need and the applications, we will send the detailed technical data and drawing to you for your evaluation and confirm.
Q: How long is the delivery time?
A: It depends on the order quantity ,Usually it takes about 30 days to produce a full 20'contanier.
Q: Can you send me your catalogue?
A: Yes, please contact us.We can share with our catalogue for you by email.
