Features
Low Transmission Loss
The motor of the Forward Curve Centrifugal Fan is directly connected to the impeller, eliminating intermediate links such as transmission belts and pulleys, reducing energy conversion losses by about 5%-10%, and significantly improving overall efficiency.
High-efficiency Impeller
The forward-inclined blade structure adopts a larger number of blades, denser angles, and a larger airflow contact surface compared to backward-inclined or radial blades, allowing the fan to stably deliver up to 20,000 m³/h of air within the rated pressure range.
Vibration Control
Through high-precision dynamic balancing technology, the dynamic balance of the Forward Curve Centrifugal Fan reaches G4.0, and the impeller vibration is controlled below 1.0mm/s, effectively reducing the noise and wear caused by mechanical vibration.
Application
It is widely used in air-conditioning terminal equipment, central air-conditioning systems, ventilation, and other HVAC systems, and is suitable for places that require large air volume and low-pressure air delivery.
Quality Certifications
We hold certifications including ISO9001, ISO45001, CE, UL, and several patents.
Packing
Our fans are usually packed in 120cm x 80cm pallet boxes to ensure the product's transportation safety. We can also provide customized packaging solutions according to customer needs to ensure that the product is delivered intact.
FAQ
Q: What is a Forward Curve Centrifugal Fan?
A: Forward Curve Centrifugal Fan is a centrifugal fan with forward-inclined blades, suitable for low-pressure and high-air-volume applications, and widely used in HVAC systems, air handling units, and other equipment.
Q: What is the maximum air volume and pressure of this fan?
A: The air volume range is 1000 m³/h to 20000 m³/h, and the pressure range is 100 Pa to 900 Pa, which meets the needs of most air conditioning terminal systems.
Q: What are the advantages of the Forward Curve Centrifugal Fan compared with backward-inclined fans?
A: Forward-inclined fans can provide greater air volume output at the same size, operate more efficiently in low static pressure applications, and are particularly suitable for systems with high air volume requirements but low pressure.
Q: Why can the impeller maintain low-vibration operation?
A: Each Forward Curve Centrifugal Fan is subjected to G4.0 level dynamic balancing before leaving the factory to ensure that the vibration speed is less than 1.0 mm/s, which is more stable and has a longer life.
Q: What are the limitations of the applicable working environment?
A: The temperature range is 20℃~40℃, and it is suitable for non-corrosive and non-viscous gas delivery occasions below 1000 meters above sea level.
Q: What are the guarantees for delivery and after-sales?
A: The factory has its production line, and conventional models support fast delivery, provide complete performance curves, drawings, pre-sales technical docking, and after-sales service that responds within two hours.
Q: Is Forward Curve Centrifugal Fan internationally certified?
A: Yes, the product has passed ISO9001, CE, UL, and other international certifications to ensure its stable performance, safety, and reliability, and can be smoothly exported to Europe, the United States, and major global markets.
Q: What typical industries is are Forward Curve Centrifugal Fan suitable for?
A: It is mainly suitable for HVAC terminal equipment, air handling units (AHU), commercial/industrial air supply systems, etc., and is particularly suitable for large air volume and low static pressure occasions.
Q: Is after-sales service guaranteed?
A: It provides a response mechanism within 2 hours, supports remote fault diagnosis, video guidance installation, and debugging services; it can also provide a fast supply of spare parts for long-term cooperative wholesale customers.
Q: What are the things that should be kept in mind for installation and operation?
A: 1) When installing the fan, the air duct weight shall not be applied to the housing, and the shaft must be kept horizontal. And the flexible connector, if any, should not be stretched too tightly.
2) Make sure there is no abnormal sound when rotating the impeller after installation.
3) Stop regularly to check the link bolts, set screws, etc., must be tightened.
4) Keep the fan clean to prevent debris from entering the fan and affecting normal use.
