IP Protection Level of Cooling Fan

2024-12-31 |

Cooling fans are widely used, and their application environments are different. In harsh environments, such as outdoors, damp and dusty places, cooling fans are generally equipped with waterproof grade, that is, IPXX.

IP is the abbreviation of Ingress Protection, and IP grade is the protection grade against foreign body intrusion of electrical equipment shell, which comes from IEC 60529, the standard of International Electrotechnical Commission, which was also adopted as the national standard of the United States in 2004. In this standard, for the protection of electrical equipment enclosure against foreign objects, the format of IP grade is IPXX, where XX is two Arabic numerals, the first mark number indicates the contact protection and foreign object protection grade, and the second mark number indicates the waterproof protection grade.

IP is the code used to identify the protection level in the world. The IP level consists of two numbers. The first number indicates the range of dust resistance of the equipment, I represents the level of preventing solid foreign objects from entering, and the highest level is 6; The second number indicates the degree of waterproof, P represents the level of preventing water ingress, and the highest level is 8. For example, the protection grade of industrial cooling fan, ventilation system fan and air radiator fan is IP54, which is the most basic waterproof grade for short, namely, three-proof paint. The process is to immerse the whole PCB board. Now, the highest waterproof grade that the cooling fan can achieve is IP68, which is completely isolated from the outside world by vacuum coating or glue filling.

The first digit indicates the dustproof index:

No.	Scope of protection	Description
0	No protection	No special protection for people or things outside
1	Prevent the intrusion of solid foreign objects larger than 50mm	Prevent the human body (such as the palm) from accidentally contacting the internal parts of the appliance, and prevent the intrusion of foreign objects of larger size (diameter greater than 50mm)
2	Prevent the intrusion of solid foreign objects larger than 12.5mm	Prevent people's fingers from touching the internal parts of the appliance, and prevent foreign objects of medium size (diameter greater than 12.5mm) from intruding
3	Prevent the intrusion of solid foreign objects larger than 2.5mm	Prevent tools, wires and similar small foreign objects with a diameter or thickness greater than 2.5mm from intruding and contacting the internal parts of the appliance
4	Prevent the intrusion of solid foreign objects larger than 1.0mm	Prevent tools, wires and similar small foreign objects with a diameter or thickness greater than 1.0mm from intruding and contacting the internal parts of the appliance
5	Prevent foreign objects and dust	Completely prevent the intrusion of foreign objects. Although the intrusion of dust cannot be completely prevented, the amount of dust intrusion will not affect the normal operation of the electrical appliance
6	Prevent foreign objects and dust	Completely prevent the intrusion of foreign objects and dust

The second digit indicates the waterproof index:

No.	Scope of protection	Description
0	No protection	No special protection for people or things outside
1	Prevent the intrusion of solid foreign objects larger than 50mm	Prevent the human body (such as the palm) from accidentally contacting the internal parts of the appliance, and prevent the intrusion of foreign objects of larger size (diameter greater than 50mm)
2	Prevent the intrusion of solid foreign objects larger than 12.5mm	Prevent people's fingers from touching the internal parts of the appliance, and prevent foreign objects of medium size (diameter greater than 12.5mm) from intruding
3	Prevent the intrusion of solid foreign objects larger than 2.5mm	Prevent tools, wires and similar small foreign objects with a diameter or thickness greater than 2.5mm from intruding and contacting the internal parts of the appliance
4	Prevent the intrusion of solid foreign objects larger than 1.0mm	Prevent tools, wires and similar small foreign objects with a diameter or thickness greater than 1.0mm from intruding and contacting the internal parts of the appliance
5	Prevent foreign objects and dust	Completely prevent the intrusion of foreign objects. Although the intrusion of dust cannot be completely prevented, the amount of dust intrusion will not affect the normal operation of the electrical appliance
6	Prevent foreign objects and dust	Completely prevent the intrusion of foreign objects and dust

The Industrial Axial Fans And Advantage Of Axial Flow Fan

2024-04-18 |

An industrial axial fan is a type of fan that is designed to move air parallel to the fan's axis of rotation. Unlike centrifugal fans, which move air at a right angle to the fan's blade, axial fans create airflow in the same direction as the fan's rotation. These fans are commonly used in various industrial applications, such as cooling systems, ventilation, and air circulation in large spaces.

The design of industrial axial fans typically includes blades that resemble airplane propellers. They are efficient in moving large volumes of air, making them suitable for applications where high airflow is required. These fans are often found in industries such as manufacturing, power generation, and HVAC (heating, ventilation, and air conditioning) systems.

Here are some key features and aspects of axial fans:

Blade Design:

Axial fans have blades that resemble those of an airplane propeller. These blades are mounted on a central hub and rotate around the axis of the fan.

Airflow Direction:

The primary characteristic of axial fans is that they generate airflow in the same direction as the fan's rotation. Air is drawn into the fan at one end and expelled at the other.

Applications:

Axial fans are commonly used in various industrial and commercial applications where high airflow is required at relatively low pressure. This includes cooling electronic equipment, ventilation in industrial spaces, air circulation in HVAC systems, and cooling of machinery.

Efficiency:

Axial fans are known for their efficiency in moving large volumes of air. They are particularly effective when the application demands a high flow rate without the need for significant pressure buildup.

Energy Efficiency:

In situations where the primary requirement is a high flow rate of air at low pressure, axial fans are often more energy-efficient compared to other types of fans.

Mounting Orientation:

Axial fans are typically mounted in a way that allows air to flow along the axis of the fan. They can be installed in various configurations, such as wall-mounted, ceiling-mounted, or in-line with ductwork.

Noise Levels:

Axial fans generally produce lower noise levels compared to some other types of fans, especially at lower speeds. This makes them suitable for applications where noise is a consideration.

Variability in Size:

Axial fans come in a range of sizes, from small fans used in personal electronics to large industrial fans used in ventilation systems for large buildings.

While axial fans have their advantages, it's important to consider the specific requirements of the application to determine whether they are the most suitable choice, especially when factors like pressure, space constraints, or noise levels come into play.
