Package of Air Conditioner Fan Blade

Air conditioner fan blade is manufactured by injection molding from engineering plastics, serving as core components in ventilation equipment such as blowers and HVAC systems. Its rotation generates airflow, facilitating air circulation.

Constructed from plastics including PP, ABS, FRP, polyurethane resin, PET, and nylon, air conditioner fan blade offers advantages such as lightweight construction, low cost, and corrosion resistance, making them ideal for indoor and outdoor applications in commercial, residential, and industrial settings.

Owing to the low melting point of plastics and their high malleability, fan blades can be engineered with enhanced aerodynamic properties. Examples include backward-curved or olive-shaped blades featuring complex surfaces, which effectively boost airflow volume and pressure while reducing energy consumption.

    8 Common Types of Air Conditioner Fan Blade

    Cross Flow Fan Blade

    Cross Flow Fan Blade

    The plastic cross flow fan blade is a long cylindrical structure, which is made by injection molding and ultrasonic welding. Its unique cross-flow design can form a wide and uniform airflow coverage layer, providing a stable laminar air barrier.
    Plastic Blower Fan Blade

    Plastic Blower Fan Blade

    Plastic blower fan blade is the “heart” of many ventilation and heat dissipation equipment. It rotates at high speed driven by the motor, forming centrifugal force to suck in air axially and throw it out radially, thus generating a continuous flow of air.
    Axial Fan Blade

    Axial Fan Blade

    The profile of efficient axial fan blade is wing-shaped, rather than flat, and this design produces greater wind pressure and reduces drag. The resulting airflow is parallel to the rotating shaft, pushing large amounts of air along a straight line.
    Centrifugal Fan Blade

    Centrifugal Fan Blade

    The centrifugal fan blade consists of a front disc, rear disc, blades, and hub. Air is drawn in axially, rotated 90℃ within the impeller, and then ejected radially at high speed. It is suitable for systems that require overcoming pipeline resistance.
    Backward Curved Fan Blades

    Backward Curved Fan Blades

    The top of the backward curved blades is bent in the opposite direction to the rotation direction of the impeller. This design forms a strong structure, so that it can maintain a stable power even when the wind volume is too large, thus protecting the motor.
    Forward Curved Fan Blades

    Forward Curved Fan Blades

    In contrast to the backward curved type, the forward curved fan blades bend in the same direction as the impeller rotation. At the same size and speed, it can produce higher static pressure. It is compactly designed and cheaper to operate.
    Plastic Exhaust Fan Blade

    Plastic Exhaust Fan Blade

    The design and material of the blades directly affect the performance, efficiency and noise level of the exhaust fan. The plastic blades are corrosion resistant, lightweight, low noise, easy to process, suitable for kitchen, bathroom, industrial ventilation, etc.
    Air Conditioner Fan Motor

    Air Conditioner Fan Motor

    Motors are widely used in air conditioning units, commonly found in condenser fans, blowers, and combustion fans. They power ventilation systems to ensure proper operation of air conditioners. We offer a comprehensive range of options for your selection.

    Features of Air Conditioner Fan Blade

    Light Weight

    Light Weight

    ABS plastic blades can be more than 30% lighter than metal blades, effectively reducing the load of the motor, thus saving energy consumption.
    High Plasticity

    High Plasticity

    Plastic material can be molded into a variety of shapes. You can also use reinforcement to improve the rigidity of the blade and prevent deformation.
    Resistance to Corrosion

    Corrosion Resistant

    Plastic blades will not rust, especially suitable for humid, dust or chemical gas environment, such as workshop ventilation, sewage treatment station ventilation, etc.
    Cost-effective

    Cost-Effective

    The raw material and production cost of plastic is usually lower than that of metal blades, achieving higher cost effectiveness.

    Metal vs Plastic Air Conditioner Fan Blade

    Metal blades are made of materials including stainless steel 304/316, copper alloy, and aluminum alloy. Plastic options include PP, reinforced AS, ABS, and ABS with Glass Fiber. If you’re unsure whether to choose plastic or metal blades, keep reading for the detailed comparison between them.
     
    Metal fan blades are generally durable and can withstand high temperatures, making them ideal for high-performance or industrial applications where high heat and durability are required. They are heavier than plastic, resulting in higher stability; however, they require more powerful motors.
     
    Plastic fan blades are lighter, and more corrosion-resistant than their counterparts. It saves cost, that is ideal for home and other light commercial fans. They operate with less noise and are easier to install and move.
    Metal vs Plastic Fan Blades

    Applications of Air Conditioner Fan Blade

    Household Air Conditioner

    Household Air Conditioner

    Both indoor and outdoor units of household air conditioners require blades. The indoor unit typically uses through-flow or centrifugal blades, while the outdoor unit employs axial-flow blades. These components function through distinct structural designs and operational principles to guide airflow in specific directions, ensuring the air conditioner operates efficiently.
    Automotive Air Conditioners

    Automotive Air Conditioners

    Compared with household air conditioners, cars require more space for the blades, so compact centrifugal or axial flow blades are popular in car air conditioners. These plastic blades have high rigidity and can adapt to the high temperature and vibration environment inside the car.
    Air Curtains

    Air Curtains

    Cascading air blades are the ideal choice for air curtains. They are usually installed above the door to create a uniform, continuous curtain of air that effectively blocks outdoor microbes such as dust, smoke, odors and insects, and prevents indoor heating and cooling from escaping, saving electricity.
    Water Cooling Air Conditioner

    Water Cooling Air Conditioner

    Water-cooled air conditioners are often located in humid environments, so corrosion-resistant plastic blades are the perfect choice. They effectively resist corrosion from moisture and chemicals, preventing rust like metal blades do, thus ensuring long-term stable operation of the equipment.
    Fan Heaters

    Fan Heaters

    The plastic fan blades in the heater need to withstand high outlet temperature. Engineering plastics, such as PPS, can maintain stable shape and function at a certain high temperature, and its axial flow design can effectively blow hot air uniformly.
    Elevator Ventilation Blower

    Elevator Ventilation Blower

    The ventilation system of elevator cabins has a very limited space and high noise control requirements. Small axial flow or centrifugal plastic blades can well balance air volume, volume and noise, ensuring fresh air in the cabin and keeping the operating sound at a low level.
    Commercial Air Conditioning

    Commercial Air Conditioning

    Commercial air conditioners are located in large shopping malls, supermarkets, hospitals or other public areas, which require higher durability, air volume and noise control of the blades. The glass fiber reinforced plastic blades can operate stably for a long time and meet the requirements of low noise in commercial occasions.
    Air Purifier

    Air Purifier

    The multi-blade centrifugal fan is the core of the air purifier. It can generate stable and continuous pressure under the premise of low noise, forcing the air to pass through HEPA filter, activated carbon and other multiple filter layers to achieve high efficiency purification.
    Tower Cooling Fans

    Tower Cooling Fans

    The large axial flow fan blade used in cooling tower needs to have high strength and weather resistance, so as to withstand the harsh outdoor environment, such as sun, rain, temperature difference, etc., and maintain long-term efficient operation, so as to ensure the heat dissipation efficiency of cooling tower.

    Mold Manufacturing Process

    Our Mechanical Design services include complete structural design, Stack-up design, tolerance analysis, material selection DFMEAFM and DFA., one of Design Integrity’s most valuable tools in new product design is the failure modes and effects analysis (FMEA).
