The 120 mm axial fan impeller is the main component of an axial fan. It generates pressure to move the airflow. There are many designs for the impeller.
Cable duct axial fan impeller
The cable duct is the space where all the electrical wires and cables lie in a house or building. The area is usually dark, and some places do not get much airflow. In these areas, a two-blade or three-blade axial fan impeller can be used. The plastic or metal blades of the impellers are applied in a way that they do not make a lot of noise when they move. Even though there is very little space for the air between the blades, the airflow is sufficient.
Circular axial fan impeller
This type of rear or hubless circular axial fan impeller has a circular disc shape. The chord width is large, and the angle of the blade is between 15 and 35 degrees. Circular fans with a high blade angle give out more pressure and push the air farther. They are used at the back of the tube in a pocket and need a bigger space to move around. The circular impellers with a lower blade angle need less space to move around. So, they are used in small circular ducts.
Plug axial fan impeller
The impeller has blades that extend from the hub to the tip. The design is based on the DC plug style. This style replaces the DC plug style. The impeller works very well. It moves a lot of airflow against the resistance of high pressure.
The 120 mm axial fan impeller has several vital specifications that customers should know before making a purchase. They include the airflow, speed, static pressure, voltage, noise level, bearing, and energy efficiency.
The main purpose of the impeller is to increase the volume of air flowing into the machine. It accomplishes this task by rotating at a specific speed. The speed of the axial fan impeller can be constant or variable. However, in some models, the speed may translate to a flow rate between 60 and 120 CFM. If customers require a higher volume of airflow, they will need to get an impeller that operates at higher speeds.
The axial fan impeller has to overcome the resistance from the surroundings to increase the flow of air. This resistance is known as static pressure. The 120 mm axial fan impeller working against this pressure will only provide a higher volume of airflow if it is designed to do so. Users may not notice the static pressure in the specifications, but it is an important factor to consider if the goal is to improve airflow.
The impeller operates on different voltages depending on its design. Some models will work optimally with 12V, while others will require 230V. Business buyers should assess the operating environment of the applications in need of the impeller to determine the ideal voltage.
When shopping for the 120 mm axial fan impeller, it is essential to consider the noise level it produces. Ignoring the noise level can lead to a very uncomfortable working environment. Some manufacturers will include the noise level in decibels in the specifications. Models like the brushless DC have a noise level of about 25 to 38 decibels at 12V to 24V. At lower voltages, the noise may be lower.
Other specifications of the axial fan impeller to consider include the bearing and energy efficiency. The bearing affects energy use and operating noise, while the energy efficiency relates to how much energy the impeller consumes operating at its best performance in a given environment.
Taking good care of the air extractor fan impeller can lengthen its life and keep working well. So, it's a good idea to do regular inspections and cleaning. People shouldn't let dust or other things build up on the fan blades because it can lower the airflow. The person in charge should clean the blades every month or two with a dry, soft brush. They should also check the belts and bearings for any signs of damage and lubricate them as required.
The axial fan impeller 120mm is applicable across various industries and fields. In some instances, it is more useful when incorporated into a larger product or system.
Industrial cooling and ventilation
A heavy industry like manufacturing, which operates under high-temperature conditions, requires efficient ventilation to keep workers comfortable. The axial impeller helps to maintain a desirable working environment by dissipating excessive heat from machines and carbon dioxide from employees. Their presence within the manufacturing space reduces the likelihood of heat-related hazards, thereby boosting productivity.
Data centers and server farms
Data centers cannot afford fan malfunctions, as they are critical to keeping servers functioning. Server farms largely depend on axial fans for reliable performance. Fans are strategically placed around servers to ensure they are well circulated and maintained. This prolongs their lifespan and helps the servers do their jobs. Without fans, servers would overheat and shut down.
Computer cooling
Desktop computers and laptops can't work without their tiny but mighty axial fans. In addition to the central processing units (CPUs) and graphics processing units (GPUs), the fans make it possible for these devices to run all day and smoothly. Newer computer models have efficient noise-reducing fans that help keep the machines cool quietly.
Medical equipment
The medical field heavily relies on axial fans for various apparatus to properly work. Medical devices like MRI machines, CT scanners, and X-ray machines, as well as life-support systems, are fitted with fans. They prevent the equipment from overheating during use, ensuring the machinery is functioning effectively, thus offering optimum patient care and safety.
Automotive cooling
Automotive vehicles have axial cooling fans. They support the functioning of the vehicles by keeping the engine as well as the radiator cool while in use. They are an important feature that helps prevents the vehicle from stalling or breaking down due to overheating, which would have resulted in engine damage.
Eco-friendly transportation
Electric cars (EVs) and hybrid vehicles use axial fans to cool their batteries. As a relatively new technology in the automotive industry, hybrid and electric vehicles heavily depend on fans for their batteries. The fans prevent them from overheating and helps extend battery life. This makes it possible for electric and hybrid vehicles to be road-ready.
Agricultural drying and ventilation
Farms employing fan ventilation and drying systems can reap the benefits of preserved grains and livestock products. The axial fan impeller’s airflow helps regulate temperature and moisture levels inside silos, greenhouses, and poultry houses. This keeps the food healthy and stops spoilage.
Choosing the right 120mm axial fan impeller for business needs involves considering various factors to ensure optimal performance, efficiency, and compatibility with existing systems.
Q1: How do buyers determine the airflow of an axial fan impeller 120mm?
A1: They can determine it by examining the fan speed (RPM), the static pressure the fan operates against, the diameter of the fan, the design of the fan blades, and the motor power.
Q2: Can an axial fan impeller 120mm work in a cold room application?
A2: Yes, it can work in a cold room application. The purpose of the 120mm axial fan in the cold room is to create a good airflow which assists in maintaining the desired temperature. Nonetheless, when using the fan in a cold room, one should consider factors like humidity and temperature.Impeller's material should have resistance to corrosion.
Q3: Do buyers need to know the fan's CFM before purchasing an axial fan impeller 120mm?
A3: Yes, they need to know the CFM before buying an axial fan. Knowing the CFM will help them determine if the fan will provide the necessary airflow for their intended application.
