What is the difference between IP65 and IP55 filter fans?

IPXX Dust and Water Resistance Rating is suitable for all equipment that requires dust and water resistance.

Dust resistance rating (indicated by the first x).

0: No protection.

1: Prevent the intrusion of large solids.

2: Prevents the ingress of medium-sized solids.

3: Prevent small solids from entering and intruding.

4: Prevent the entry of solids larger than 1mm.

5: Prevent harmful dust accumulation.

6: Completely prevent dust from entering.

Waterproof rating (indicated by the second x).

0: No protection.

1: Water droplets dripping into the shell have no effect.

2: When the shell is tilted to 15 degrees, the water droplets dripping into the shell have no effect.

3: No effect of water or rain from 60 degree corners to the enclosure.

4: Liquid splashed into the shell from any direction has no harmful effect.

5: Rinse with water without any harm.

6: Can be used in the environment in the cabin.

7: It can withstand water immersion (1m) in a short time

8: Immersion in water for a long time under a certain pressure.

IP65, which means that the product can completely prevent dust ingress and can be washed with water without any harm.

IP55, which means that the product prevents harmful dust accumulation and can be washed with water without any harm.

There is a difference in the dustproof effect, and the IP65 filter fan is static and dynamic, and no dust enters the device. IP55 filter fan prevents dust from entering when static; When dynamic, it does not prevent dust from entering. IP65 filter fans are suitable for electrical equipment with high dust protection requirements.

IP55 filter fans are suitable for electrical equipment with low dust protection requirements for power distribution.

The IP (Ingress Protection) protection rating system is drafted by the International Electronic Technical Commission (IEC), which classifies electrical appliances according to their dustproof and moisture-proof characteristics.

The IP protection level is composed of two numbers, the first number indicates the level of dust proof and prevention of foreign objects (the foreign objects referred to here include tools, and human fingers cannot touch the live part of the electrical appliances to avoid electric shock), and the second number indicates the degree of airtightness of the electrical appliances against moisture and waterproof immersion, and the larger the number, the higher the protection level.

1、The role is differentIP65 is protected against low-intensity splashing water; IP66 is to prevent high-intensity splashing, shallow water can also be put in, and the E7 in the cloud is IP66.

The application is differentThe common waterproof levels of outdoor lighting products are generally IP65 and IP66, which are enough to meet the needs of daily outdoor lighting applications, while lamps and lanterns that may be subject to water-immersed conditions such as buried lamps are generally IP67 and IP68.

Different, IP66 and IP65 waterproof levels are different, so there will be a gap between the two models of the same brand, and generally IP66 is higher than IP65.

Understanding of IP Ratings

IP protection level refers to the ability of the product to be dustproof and waterproof, the IP protection level is composed of two numbers, the first number indicates the level of dust proof and prevention of foreign objects intrusion, and the foreign objects referred to here include tools, human fingers, etc., can not touch the live part of the electrical appliance, so as to avoid electric shock. The second digit indicates the degree of containment of the appliance against moisture and water intrusion.

If the product is used in a short-term immersion environment, you can choose IP67, if the product does not involve short-term immersion in water, only outdoor land ordinary use, IP66 can meet the requirements of the use environment.

IPXX dust and water resistance rating.

Dust resistance rating (the first x indicates) Water resistance rating (the second x indicates) 0 : No protection.

1: Prevent the intrusion of large solids.

2: Prevents the ingress of medium-sized solids.

3: Prevent small solids from entering and intruding.

4: Prevent the entry of solids larger than 1mm.

5: Prevent harmful dust accumulation.

6: Completely prevent dust from entering.

0: No protection.

1: Water droplets dripping into the shell have no effect.

2: When the shell is tilted to 15 degrees, water droplets dripping into the shell have no effect3: Water or rain from the corner of 60 degrees to the shell has no effect4: Liquid splashed into the shell from any direction has no harmful effect.

5: Rinse with water without any harm.

6: Can be used in the environment in the cabin.

7: It can withstand water immersion (1m) in a short time

8: Immersion in water for a long time under a certain pressure.

Therefore, the display instrument is marked as IP65, which means that the product can completely prevent dust from entering and can be washed with water without any harm; Labelled IP66, it means that the product is completely protected against dust ingress and can be used in the cabin environment.

It can be said that there is no difference in appearance, the difference between IP65 and IP55 is in the sail state in the dust-proof field test, but the test method of 6 and 5 is exactly the same, but the qualification criteria are different, 6 is not allowed to have powder next to the car to shout dust in, 5 is to have a small amount of dust in.

The "6" in the protection level IP65 of the explosion-proof motor is 6 level dustproof, and "5" is level 5 waterproof.

IP55 filter fan, after the fan is powered on, it cannot achieve IP5X dustproof filtration, because IP5X filter fan is the dustproof effect when the fan is not powered on, that is, static operation, once powered on, dynamic operation, it is not dustproof at all;

If you need the fan to be dustproof when the fan is powered on and ventilated, you need to choose an IP65 filter fan.

We use Yuanding Electric SOTOP, they can reach IP55, and there is an authoritative certification.

Shanghai Tingxiang has it, we have been using it, the effect is very good, there is a third-party certification.

Dustproof and waterproof [from: Wanken motor dustproof and waterproof IP level detection device] The protection level adopts the IP rating standard recommended by the International Electrotechnical Commission (IEC), and the level is different for different installation sites. You can refer to the instructions below to select the details.

In the rating standard, " is a two-digit number, with the first digit indicating the degree of protection against solids and the second digit indicating the level of protection against liquids. There are 7 levels of solid protection, which are represented by 0-6; There are 9 levels of liquid protection, which are expressed from 0 to 8.

Dustproof rating. 0: No protection.

1: Prevent the intrusion of large solids.

2: Prevents the ingress of medium-sized solids.

3: Prevent small solids from entering and intruding.

4: Prevent the entry of solids larger than 1mm.

5: Prevent harmful dust accumulation.

6: Completely prevent dust from entering.

Waterproof rating. 0: No protection.

1: Water droplets dripping into the shell have no effect.

2: When the shell is tilted to 15 degrees, the water droplets dripping into the shell have no effect.

3: No effect of water or rain from 60 degree corners to the enclosure.

4: Liquid splashed into the shell from any direction has no harmful effect.

5: Rinse with water without any harm.

6: Can be used in the environment in the cabin.

7: It can withstand water immersion (1m) in a short time

8: Immersion in water for a long time under a certain pressure.

Test Method: For example, if there is a scale or display meter marked IP65, it means that the product can completely prevent dust ingress and can be washed with water without any harm.

The provisions of the IPXX rating for waterproof testing.
