When planning the bathrooms for your building, the type of hand dryer you select has an impact on the perception of the facilities. The sleek, modern designs of the Mitsubishi Electric Wave range are a popular choice and help to create an attractive and quiet environment for users, as well as being highly efficient and quiet in use.

Choosing between hands-in and hands-under designs has an impact on how the dryers should be installed, and it is also important to consider the needs of users when deciding which system is best for your bathrooms.

Hands-Under Hand Dryers

Hands-under hand dryers are a more conventional design that most people are familiar with. Modern jet hand dryer designs such as the Mitsubishi Electric Wave u02 are much quieter than conventional warm air hand dryers and use less energy.

Design and Operation:

Hands-under hand dryers operate by users placing their hands below the unit. The air is blown downwards to dry hands, usually from a single nozzle or multiple nozzles.

These dryers are straightforward and easy to use, with a design that fits well into most bathroom designs. A choice of colours is available including both black and metallic finishes to match the décor of your building.

Benefits of Hands-Under Hand Dryers:

This type of hand dryer is intuitive for users as the drying method is so familiar. Designs are compact and can easily fit into smaller spaces. The design is also ideal for children as it can be mounted closer to floor level, making it easier to reach.

Mounting Height:

Hands-under hand dryers need to be mounted slightly higher on the wall than alternative designs. There are recommended heights for different users to ensure comfort and accessibility:

• Adult male: 1,170mm
• Adult female: 1,120mm
• Children Aged 4 – 7: 810mm
• Children Aged 7 -10: 910mm
• Children Aged 10 – 13: 1,020mm
• Children Aged 13 – 17: 1,120mm
• Wheelchair users: 940mm

Hands-In Hand Dryers

Featuring a more futuristic design, hands-in hand dryers like the Mitsubishi Electric Wave i01 are an increasingly popular choice, especially in public bathrooms where they fit seamlessly into almost any décor.

Design and Operation:

Hands-in hand dryers are designed with a slot or opening into which users insert their hands. High-speed air jets located on either side of the slot blow air at high velocity to dry hands quickly and efficiently.

These dryers often feature a unique design that directs the airflow to remove water from hands, collecting the water in a built-in reservoir or drip tray to prevent puddles on the floor.

Benefits of Hands-In Hand Dryers:

Hands-in dryers are known for their fast-drying times, typically taking 10-15 seconds, and the design also makes them quieter in use as the drying area is well shielded. They are a very hygienic choice. The touchless design and HEPA filters, coupled with an antibacterial surface means that they help stop the spread of germs.

A major benefit of hands-in hand dryers is that they catch the water from the user’s hands which keeps the floor of the bathroom dry and reduces the risk of slipping.

Mounting Height

Hands-under hand dryers need to be mounted lower on the wall than hands-under designs. In most cases, the recommended mounting height is 120mm lower to allow easy access. While hands-in dryers can be used by younger children, the design can be more difficult to use, so they may

• Adult male: 1,050mm
• Adult female: 1,000mm
• Children Aged 13 – 17: 1,000mm
• Wheelchair users: 875mm
