Description

11-62 Multi-Wings Centrifugal Fan

* Model No.3E to No.8E of 11-62 (E-type) multi-blade centrifugal fan adopts a belt-driven design, improved from the 11-62 A-type direct-drive model, consisting of a multi-wing impeller, scroll casing, belt pulley assembly, and heavy-duty motor. ·

* The impeller features multi-forward curved blades with optimized aerodynamic profile, revised by strict static and dynamic equilibrium, ensuring smooth operation, large air volume, and low noise. ·

* The fan is available with two motor configurations: E-type top-mounted motor and E-type bottom-mounted motor, both with a compact structure and aesthetic appearance, suitable for modern commercial building ventilation systems. ·

* The belt drive system allows flexible speed adjustment via pulley changes, meeting variable airflow and pressure demands in different application scenarios. ·

* The casing and impeller are made of high-quality steel plate, with the impeller treated for anti-corrosion and wear resistance, suitable for long-term continuous operation in catering and commercial environments.

11-62 Model Features

Material Properties

Featured by large air volume, low noise, compact structure, and flexible belt drive design, 11-62 (E-type) centrifugal fans are ideal ventilation equipment for modern hotels, restaurants, dining halls, and as matching units for air conditioning systems. They are widely used for air supply, exhaust, and air exchange in public and commercial buildings.

Standard models are equipped with ordinary three-phase asynchronous motors. Explosion-proof variants (B-11-62) with flameproof motors are available for spaces with volatile flammable gases. Stainless steel customized versions (F-11-62) can be provided for conveying corrosive gases, with the same performance parameters and installation dimensions as the standard model.

Benefits

The transporting medium is air or other non-corrosive, non-explosive, and harmless gases. The conveyed gas shall not contain any adhesive substances, excessive dust, or hard particles with a concentration exceeding 150mg/m³, and the medium temperature shall not exceed 80℃. With an explosion-proof motor, the B-11-62 variant can be used for ventilation in environments with volatile flammable gases.

Fan Structure

The belt-driven design of 11-62 (E-type) offers advantages such as easy maintenance, flexible speed adjustment, and reduced motor vibration transmission. The fan is available with two motor installation configurations: top-mounted and bottom-mounted, allowing adaptation to different installation space requirements. The fan has obtained the National Industrial Product Production License (QS mark) for refrigeration equipment.

Model Selection

The series supports multiple rotating speeds from 560r/min to 1420r/min with power ranging from 1.1kW to 30kW. Diversified speed-power collocations cover a wide airflow and full pressure scope to satisfy different commercial building ventilation and pipeline resistance requirements.

Q1: What is the main difference between the 11-62 E-type and A-type fans?
A1: The 11-62 E-type adopts a belt-driven design, offering larger air volume, lower noise, and flexible speed adjustment compared to the direct-drive A-type model, making it more suitable for variable ventilation demands in commercial buildings.

Q2: Can this fan be used for kitchen exhaust applications?
A2: Yes, the multi-blade design and low noise level make it ideal for kitchen ventilation and smoke exhaust in restaurants, hotels, and dining halls.

Q3: What are the two motor configurations for the E-type fan?
A3: The E-type fan is available with top-mounted and bottom-mounted motor configurations to adapt to different installation space requirements in commercial buildings.

Q4: Can I adjust the fan speed to meet my specific airflow requirements?
A4: Yes, the belt-driven design allows speed adjustment by changing pulley sizes, enabling flexible matching of airflow and pressure to different working conditions.

Q5: What is the maximum allowable temperature of the conveying gas?
A5: The standard model is suitable for conveying gases with temperatures up to 80℃. Special high-temperature versions can be customized for higher temperature applications.

Q6: Is an explosion-proof variant available for use in environments with flammable gases?
A6: Yes, the B-11-62 explosion-proof variant with a flameproof motor is available for ventilation in spaces with volatile flammable gases.

Q7: Can the fan be customized with different outlet angles?
A7: Yes, the fan can be provided with multiple outlet angles (0°, 90°, 180°, 270°) to match existing ductwork layouts in your building.

Q8: What certifications does this product have?
A8: The 11-62 (E-type) series has obtained the National Industrial Product Production License (QS mark) for refrigeration equipment. CE-certified motors can also be provided for European customers.

Q9: What maintenance is required for the belt-driven E-type fan?
A9: Regular belt tension checks, bearing lubrication, and impeller cleaning are recommended to ensure long-term stable operation. The belt drive design also allows for easier maintenance compared to direct-drive fans.

Q10: Can the fan be installed in both horizontal and vertical orientations?
A10: The fan can be installed horizontally or vertically according to the installation space and duct layout requirements, as long as the motor and bearing assembly are properly aligned and lubricated.
