The materials of Blower fans are diverse, each with its own advantages and disadvantages. The following is a comparison of several common materials:

Metal material

Cast iron

Advantages: It has excellent wear resistance, corrosion resistance and compressive strength, capable of withstanding high pressure and load, and is suitable for some industrial applications with high strength requirements. Meanwhile, cast iron material has better shock absorption performance, and the vibration and noise generated during operation are relatively small.

Disadvantages: Due to its high density, the overall weight of the blower fan is relatively heavy, making installation and maintenance rather inconvenient. Moreover, the processing performance of cast iron is relatively poor, the production cycle is long, and the cost is also high.

Carbon steel

Advantages: High strength, good toughness, and capable of maintaining stable performance in various working environments. Carbon steel has excellent processing performance and can be made into complex shapes through various processing techniques to meet the design requirements of different types of blowers and fans. In addition, the cost of carbon steel is relatively low and it has a high cost performance.

Disadvantages: It has poor corrosion resistance and is prone to rust in damp or corrosive gas environments. Special anti-corrosion treatments, such as spraying anti-rust paint or galvanizing, are required; otherwise, it will affect the service life and performance of the blower fan.

Stainless steel

Advantages: It has excellent corrosion resistance, oxidation resistance and high-temperature resistance, and can operate stably for a long time in harsh working environments without frequent anti-corrosion maintenance. The surface of stainless steel is smooth and the resistance to gas flow is small, which helps to improve the efficiency of the blower and fan.

Disadvantages: The cost is relatively high, and the price is much higher than that of ordinary carbon steel materials. Moreover, the processing of stainless steel is rather difficult, with high requirements for processing techniques and equipment, which increases the cost and difficulty of production and manufacturing.

Plastic material

Common engineering plastics

Advantages: Light in weight, easy to install and maintain, and it also has good insulation performance and chemical stability, and is not easily corroded by acids, alkalis and other chemical substances. The molding process of plastic materials is simple and the production efficiency is high. It can be made into blowers and fans of various shapes and sizes to meet the needs of different users.

Disadvantages: It has relatively low strength and rigidity, and cannot withstand high pressure and load. It is generally suitable for some small Blower fans with low pressure requirements. In addition, plastic has poor heat resistance and is prone to deformation in high-temperature environments, which affects the performance and service life of fans.

High-performance engineering plastics

Advantages: It has high strength, rigidity and heat resistance, and can to a certain extent make up for the deficiencies of ordinary engineering plastics. Some high-performance engineering plastics also have good wear resistance and self-lubrication, which can reduce the friction loss during fan operation and improve efficiency.

Disadvantages: The cost is relatively high, and the price is usually much higher than that of ordinary engineering plastics. Moreover, the processing of high-performance engineering plastics is rather difficult and requires the adoption of special processing techniques and equipment.

Composite material

Glass fiber reinforced composite material

Advantages: It features light weight, high strength, corrosion resistance, good insulation performance, etc. It also has excellent formability and can be made into various complex-shaped blowers and fans. Glass fiber reinforced composites have good weather resistance and can be used for a long time in outdoor environments without significant performance degradation.

Disadvantage: Compared with metal materials, its rigidity and hardness may be slightly inferior. When subjected to significant external force impacts, it is prone to damage or cracking. In addition, the repair of composite materials is relatively difficult. Once damage occurs, the repair cost is high.

Carbon fiber reinforced composite material

Advantages: It has extremely high strength and rigidity, yet is very light in weight, making it an ideal high-performance material. Carbon fiber reinforced composite materials also have excellent corrosion resistance, high-temperature resistance and fatigue resistance, and can maintain stable performance under extreme working conditions.

Disadvantage: It is extremely expensive and is currently the most expensive material for blower fans. Its processing technology is complex and has high requirements for production equipment and technology, which limits its large-scale application.

Blower fans made of different materials vary in performance, cost, service life and other aspects. When making a choice, it is necessary to comprehensively consider factors such as the specific usage environment, work requirements and budget to determine the most suitable material.
