When using a hot air blower in a humid environment, waterproof performance is a key factor that must be considered. The following is a specific analysis and suggestions:
Key indicators of waterproof performance
Waterproof grade standard:
Hot air blowers that meet IPX4 or higher waterproof standards can effectively prevent water vapor and water droplets from entering the internal circuits, ensuring the safety of electrical components. IPX4 rating can withstand water splashing from all directions, IPX5 can prevent continuous low-pressure water spraying, and IPX6 can prevent excessive water spraying.
For instance, the Emmett bathroom heater with IPX4 water resistance can be used normally in a damp bathroom environment, but it is necessary to avoid direct water exposure.
Moisture-proof and anti-corrosion design
High-quality hot air blowers should have moisture-proof performance to prevent short circuits or component corrosion caused by damp environments.
Some models adopt special processes (such as vacuum coating and potting) to enhance their waterproof performance. For instance, the 28080 cooling fan, through the fourth-generation low-pressure vacuum potting technology, has achieved an IP68 waterproof rating and can operate underwater for a long time.
The influence of a humid environment on hot air blowers
Motor and insulation performance:
A humid environment can easily cause condensation inside the motor, affecting insulation performance and even leading to short circuits.
When the air humidity exceeds 94%, metal parts (such as iron cores and silicon steel sheets) are prone to rust, reducing the efficiency of the motor.
Bacterial growth and aging
High-temperature and high-humidity environments are prone to bacterial growth, accelerate the aging of insulating materials, and increase the risk of short circuits.
Purchasing suggestions
Give priority to choosing models with a high waterproof rating:
For damp environments such as bathrooms, it is recommended to choose a hot air blower with an IPX4 or higher waterproof rating.
For industrial or outdoor damp environments, it is recommended to choose models with a water resistance rating of IPX6 or above.
Pay attention to moisture-proof and anti-corrosion design:
Choose a hot air blower with moisture-proof and anti-corrosion functions, such as a model that adopts a sealed waterproof structure and an environmentally friendly fireproof and waterproof three-proof paint process.
Regular maintenance and inspection:
Hot air blowers used in humid environments need to have their sealing performance checked regularly. Any abnormalities found should be repaired or replaced in a timely manner.
Special scene recommendation
Bathroom scene:
We recommend models with IPX4 waterproof rating, moisture-proof design and overheat protection function, such as the Emmett Graphene Bathroom heater HP20-K6-3. Its triple waterproof design and graphene heating technology make it suitable for bathroom use.
Industrial humid environment
It is recommended to use a hot air blower with a high waterproof process (such as fully automatic low-pressure vacuum potting), such as the 28080 cooling fan. Its IP68 waterproof rating and anti-corrosion design make it suitable for humid environments in coastal areas, chemical plants, etc.
