An axial flow fan, also known as a tube axial fan or an axial fan blower, forces air to flow in the same direction as the shaft as it operates. In terms of both design and operation, an axial flow fan differs greatly from a centrifugal fan.
Consequently, the variations make each one suitable for distinct use. Axial fans are mostly used to ventilate and dissipate heat from mechanical equipment, including electrical cabinets and other such items.
The generated wind airflow wouldn’t be affected externally. To improve production, guides or stator vanes serve to straighten or fix the wind stream. Axial stream fans are often appropriate for larger flow rates with a reasonably small pressing factor acquired and centrifugal fans for smaller flow rates and a significant rise in a pressing factor.
They are used to deliver fresh air, draw air from return air channels, draw air from rotating channels, deplete air, and other functions. The size and materials of the fan are chosen based on the purpose and volume of air handled.
But certain things are to be kept in mind while buying axial fans so that you can get the comfort for what you are paying for.
Following are some of the tips for buying axial fans from Swifter fans, a reputed supplier of axial fans:
1. Fan bearing configuration
An important component to consider when evaluating the performance of an axial fan is its bearing. It is mostly used for ball bearings and sleeve bearings. The customer should select the appropriate fan with the suitable type of bearings based on their needs.
Customers also need to be aware of the axial fan engine in addition to the specific factors mentioned above. The accompanying business variables should be taken into consideration when purchasing axial fans.
2. Sound volume
A noise meter is set to 1 m from the airflow passage at the 90-degree point when an axial stream fan is operating. The tested fan operates with open airflow, little background noise, and no reverberation.
3. A fan’s operational point
The fan characteristic curve and the airflow system characteristic curve will be chosen once the airflow system has been constructed to fulfill the requirements of the fan. How do I choose?
The airflow volume and air pressure of the intersection must fulfill the requirements of the airflow volume and air pressure of the fan cooling system. Designers must test the drag characteristic curve, resistance characteristic curve, and fan characteristic curve of the cross graph.
4. Weighing and measuring
The axial fan’s weight will assist you in selecting the best options for your requirements. The difficulties that arise when trying to stack an axial fan that weighs more than 15 kilos are usually the reason why they are not favored.
Axial fan diameters are also very important. Axial fans that are either too little or too large are poor choices that might not produce the desired effects. The most prevalent type of axial fans on the market has a diameter of roughly 50 centimeters, which is the industry standard.
5. Airflow system
The proper kind of vane axial fan for your application must take airflow into account. The fan’s total efficiency is significantly influenced by the amount of air it can move. The amount of power used to move the air will depend on the density of the air, which is another factor to take into account.
The fan’s construction must be examined before purchase. The motor sealing is another reliable sign of how much emphasis was placed on safety and security throughout the production of the product. Other elements to look at include the carry handle and the exterior mesh that shields users from the blades.
Before making any purchases if you are unfamiliar with the product, it is a good idea to actively speak with service providers and get their recommendations for the safest brand or variety.
While keeping the aforementioned considerations in mind, one should always focus more on their budget. It’s crucial to avoid excessively stretching your budget to get a pricey axial fan. Keep your budget flexible enough to avoid making investments in cheap, short-lived products. Making a decent buy requires striking a balance.
A high-quality axial fan that complies with industry standards shouldn’t cost more than $700. Prior to making a purchase, getting a reasonable estimation of the market is essential. It enables you to benefit while making prudent financial decisions.
The above is some of the main things to keep in mind for buying an axial fan. However, you must conduct research and gain experience to determine whether or not axial fans are appropriate for your requirements.
These fans have grown significantly in favor in recent years across a variety of industries due to their effectiveness and efficiency in the field of all-purpose cooling. Axial fans have long been used in air conditioners, but they are currently used in practically all air conditioners around the world.
Buying an axial fan can be a complex task as there are many factors to consider. When shopping for an axial fan, it’s important to keep in mind the size, nozzle length, air flow rate, power consumption, and noise level. Additionally, one must also consider the environment the fan will be used in and the materials the fan is made of. With all these factors in mind, consumers can make an informed decision about which fan is best for their needs and budget. Ultimately, it is important to purchase an axial fan that is safe, efficient, and reliable, so that it works as intended and lasts for a long time.
