YN5-47 High-efficiency,Low-noise,air Cooled High-temperature Resistant Boiler Fan

The YN5-47 II/III series boiler fan features high efficiency, low noise, air cooling, and high-temperature resistance. It is a new type of boiler fan with high efficiency and low noise.The motor uses Y2 aluminum alloy die-casting material, which significantly reduces weight, realizes lightweight and convenient installation, and adopts an innovative design. The motor components adopt high-temperature resistant materials (including high-temperature bearings, high-temperature grease, high-temperature resistant materials, etc.). The high-temperature resistant connecting seat is connected to the fan shell, and the motor is cooled, ensuring the stable operation of the motor in high-temperature environments.It is widely applied in heating furnaces, air heaters, numerical control boilers, steam boilers, drying equipment, chemical food processing, grain machinery and other related industries. The normal operating temperature range of the fan is 160°C - 200°C.

    CHARACTERISTICS

    1. 1.Volute centrifugal structure with strong pressure boost, effectively overcomes duct and filter resistance, suitable for long-distance air supply and centralized extraction.
    2. 2.Equipped with copper-coil asynchronous motor with high insulation grade, reliable operation and long-time continuous running.
    3. 3.All-metal housing with anti-corrosion coating, robust and durable for complex industrial environments.
    4. 4.Standard square inlet and round outlet with universal interface for quick duct and equipment connection.


    • · YN5-47 II Type Impeller: Backward-inclined wide blade design with black finish; fewer blades, large air volume, moderate pressure, smooth airflow and low resistance.
    • · YN5-47 III Type Impeller: Forward-curved multi-blade design with riveted natural metal structure; dense blades, higher pressure, uniform stable airflow and strong suction capacity.

    Applicable scenarios

    Equipment cooling, industrial duct supply/exhaust, workshop dust removal, light material conveying, oven exhaust, fume purification, equipment extraction systems.


    • · Type II Impeller: General ventilation, workshop air circulation, equipment cooling, low-pressure duct exhaust, low-resistance scenarios with high air volume demand.
    • · Type III Impeller: High-pressure extraction, dust collection, material conveying, fume purification, high-resistance ducts with high air pressure demand.

    Advantages

    1. · Dual impeller grading: Two impellers cover low-pressure large-volume and high-pressure small-volume conditions, precisely matched to duct resistance and airflow demand.
    2. · Excellent pressure performance: Centrifugal boost overcomes filter, elbow and long duct resistance for long-distance delivery and centralized suction.
    3. · Stable & durable: Industrial motor + all-metal structure for 24/7 continuous operation, long service life and low maintenance cost.
    4. · Flexible installation: Standard interface, supports horizontal and vertical mounting, suitable for built-in equipment, in-duct series connection and more.
    5. · Smooth quiet operation: Dynamically balanced impeller with low vibration and noise, suitable for indoor and workshop environments.
