Automatic hand dryers are devices that use hot air or high-speed air to dry your hands after washing them. They are usually installed in public restrooms, such as restaurants, offices, hotels, and airports. They are more hygienic and eco-friendly than paper towels, which can create waste and spread germs.
There are many types and models of automatic hand dryers available on the market, each with its own features and benefits. Some of the factors that you should consider when choosing a hand dryer are:
• Power: The power of a hand dryer determines how fast and effective it can dry your hands. A higher power means a shorter drying time and a lower energy consumption. However, it may also mean a louder noise and a higher cost. The power of a hand dryer is measured in watts, and it can range from 950 watts to 1800 watts
• Air velocity: The air velocity of a hand dryer is the speed of the air flow that comes out of the nozzle. A higher air velocity means a more powerful and efficient drying performance. However, it may also mean a more turbulent and noisy operation. The air velocity of a hand dryer is measured in meters per second (m/s), and it can range from 50 m/s to 95 m/s
• Drying time: The drying time of a hand dryer is the average time it takes to dry your hands completely. A shorter drying time means a more convenient and satisfying user experience. However, it may also mean a higher power consumption and a higher temperature. The drying time of a hand dryer is measured in seconds, and it can range from 7 seconds to 15 seconds
• Temperature: The temperature of a hand dryer is the heat level of the air flow that comes out of the nozzle. A higher temperature means a warmer and more comfortable drying sensation. However, it may also mean a higher risk of overheating and burning your skin. The temperature of a hand dryer is measured in degrees Fahrenheit (°F), and it can range from 68°F to 135°F
• Sound level: The sound level of a hand dryer is the loudness of the noise that it produces during operation. A lower sound level means a quieter and more peaceful environment. However, it may also mean a lower power and a lower air velocity. The sound level of a hand dryer is measured in decibels (dB), and it can range from 50 dB to 90 dB
• Body material: The body material of a hand dryer is the substance that covers the outer surface of the device. It affects the appearance, durability, and maintenance of the hand dryer. Some common body materials are stainless steel, reinforced polymer, ABS plastic, and metal. They have different advantages and disadvantages, such as resistance to corrosion, wear and tear, damage, stains, and overheat.
• Motion sensor: The motion sensor of a hand dryer is the device that detects the presence and movement of your hands near the nozzle. It activates and deactivates the hand dryer automatically without requiring any physical contact. It makes the hand dryer more hygienic, convenient, and smart. However, it may also malfunction or misfire due to interference or obstruction.
• Best Pick: Melfi™ Automatic Hand Dryer: This is a premium hand dryer that has a heavy-duty metal housing, speed and sound controls, rib reinforcement for extra durability, and an infrared sensor for touchless operation.
