What’s the difference between conventional hand dryer and high speed hand dryer?
A conventional hand dryer uses warm air to evaporate moisture from the hands, while a high-speed hand dryer uses strong airflow to remove water more quickly. Conventional models are generally quieter and provide gentle warm air, whereas high-speed models usually offer shorter drying times, lower energy use per cycle, and more installation options for modern commercial washrooms.
Conventional and High Speed Hand Dryers
Conventional Hand Dryer:
Conventional hand dryers, such as the HK-1800 series, use warm air at a lower air speed. They are commonly selected for schools, offices, libraries, and other locations where lower noise and gentle airflow are important. Models with a rotatable air outlet may also be used for hair or face drying when the product is designed for that purpose.
High Speed Hand Dryer:
High-speed hand dryers use concentrated airflow to blow water away from the hands. Many models can dry hands within 15 seconds, while selected models can operate even faster. High-speed hand dryers are available in wall-mounted, recessed, behind-the-mirror, and deck-mounted configurations, making them suitable for a wide range of commercial washroom projects.
| Comparison Item | Conventional Hand Dryer | High Speed Hand Dryer | Best For / Selection Tip |
|---|---|---|---|
| Drying Method | Uses warm air to dry water off hands. | Uses strong, fast airflow to blow water away. | Choose based on your restroom traffic and user flow. |
| Drying Time | Usually around 25–35 seconds, depending on the model and conditions. | Usually under 15 seconds; selected models may be faster. | High-traffic restrooms should prioritize a shorter drying cycle. |
| Noise Level | Usually quieter because the wind is softer. | Can be louder due to strong wind. Some models (like HK-JA LdB) offer high speed with lower noise. | Schools and quiet offices should check the sound level (dB) carefully. |
| Energy Use | May use more heating energy and operate for a longer cycle. | Usually relies more on airflow than heat and may use less energy per drying cycle. | Green (ESG) or cost-conscious projects should check total watts and speed. |
| Installation | Commonly wall-mounted. | Many options: wall, recessed, behind-the-mirror, or deck-mounted. | Choose based on your bathroom design or space needs. |
