Product Overview

LEIPOLE’s Centrifugal Fans feature a high-efficiency impeller design that delivers powerful, stable air flow, which is ideally suited for heat dissipation and air circulation in electrical cabinets, ventilation systems, and other industrial equipment. Centrifugal fan has better static pressure and longer delivery distance than axial fan, so it is especially suitable to applying in ventilation resistance is large and the need to deep air delivery of the situation. It can provide powerful wind at a small size with high performance for occasions when high static pressure and low noise in design requirements.

Key Advantages

✅Air duct design: impeller structure optimization, delivery of air volume greatly improved, energy consumption reduced.

✅Strong static pressure output: Suitable for high resistance environment, filtration systems, ventilation ducts and etc.

✅Materials: Heavy duty PA6+GF (glass fiber reinforced nylon) or aluminum alloy impellers for excellent durability and high temperature resistance.

✅Dust and water proof: IP44 protection level, suitable for harsh industrial environments.

✅Automatic protection mechanism: With automatic recovery thermal protection. It improves the safety and reliability of the electric motor.

✅Noise free operation: optimize the design of the fan structure and motor to reduce the running noise, provide a good working atmosphere.

Applications

Use areas of Leipole Centrifugal Fans series:Manufacturing: These are used to cool electrical cabinets on the production line so as not to overheat and not let dust in.Automation: Ensure stable cooling and dust-proof for automation equipment.

Power distribution: Stable operation of power distribution equipment under high temperature environment.

Renewable resources: Used for solar and wind energy equipment cooling and dust control.

Electric vehicle charging station: Avoid overheating of charging equipment, ensuring the charging process is both efficient and safe.

Basic Knowledge

Centrifugal fan working principle: In case the suction area has a narrow opening, there would be an increase in pressure and that in turns increases the velocity through an automatic adjustment.The rotation of the impeller accelerates the air radially, and the shell guides the air into the exhaust duct to generate a higher wind pressure, so that the air can be delivered over a long distance.Used to apply in the environment with high static pressure and large air volume.

FAQ

🔹Q1: What are centrifugal fans and axial flow fans?

💡A1: Centrifugal fans are used for applications with high wind pressures, like filtration, duct ventilation, etc. Axial flow fans are used in low resistance heat dissipation scenarios, like cooling electrical cabinet.

🔹Q2: Is it possible to customize the fan?

💡A2: Yes, we are able to customize centrifugal fan of dffierent air volume, size and installation way according to the needs.

🔹Q3: How much noise does Centrifugal Fans make?

💡A3: The Centrifugal Fans of Leipole are characterized by low-noise, (50~70dB) depending on the model and Air volume.

🔹Q4: Can Centrifugal Fans be installed outdoors?

💡A4: Yes, our Centrifugal Fans have a high IP rating (IP44 for example) and is accordingly available for outdoor or harsh environment.

🔹Q5: The volume and air pressure must be determined by the person using the machine.

💡A5: The air volume and air pressure are determined by the heat generation of the equipment and the ambient temperature. Just offer your requirements and our engineers will give suggestions accordingly.
