Vent-Axia eTempest Hand Dryer 1kW (white) - 444956

This rating is based on the watt hours per dry of the hand dryer which is derived from the rated power and the time taken to dry the hands. We have used the figures based on either the manufacturer’s dry time, if yet to be in house tested or based on the in house testing dry time we have conducted. This will also be based on the most energy efficient setting, if the hand dryer is adjustable for speed and/or heat.

Watt hours per dry:

• 0 – 1.99Wh = star rating 5
• 2 – 2.99Wh = star rating 4.5
• 3 – 3.99Wh = star rating 4
• 4 – 4.99Wh = star rating 3.5
• 5 – 5.99Wh = star rating 3
• 6 – 6.99Wh = star rating 2.5
• 7 – 7.99Wh = star rating 2
• 8 – 8.99Wh = star rating 1.5
• 9 – 9.99Wh = star rating 1
• 10Wh and above = star rating 0.5

This rating is based on the manufacturers stated sound level, usually at 1m. Please see the section titled "how quiet is the." for more information and independent test results, which give a more accurate noise decibel level. These ratings will also be based on the low noise setting, if the hand dryer is adjustable for speed. Therefore at full speed the hand dryer may not be quiet, however it may be adjustable to become quiet if this is required.

Decibels (dB):

• Up to 68dB = star rating 5
• 69 – 70dB = star rating 4.5
• 71 – 72dB = star rating 4
• 73 – 74dB = star rating 3.5
• 75 – 76dB = star rating 3
• 77 – 78dB = star rating 2.5
• 79 – 80dB = star rating 2
• 81 – 82dB = star rating 1.5
• 83 – 84dB = star rating 1

This rating is based on the number of motor life cycles (number of uses) the hand dryer, in theory, will last for. This is based on the motor life expectancy given to us in hours, from the manufacturer.

The number of cycles (uses) has been calculated as follows:

(Number of seconds in the hour / seconds per dry) x motor life hours

For a more individualised longevity calculation based on your own usage numbers please use the life expectancy calculator on each product page.

Number of motor life cycles:

• 1,000,000 and over = star rating 5
• 800,000 – 999,999 = star rating 4.5
• 600,000 – 799,999 = star rating 4
• 400,000 – 599,999 = star rating 3.5
• 200,000 – 399,999 = star rating 3
• 100,000 – 199,999 = star rating 2.5
• 80,000 – 99,999 = star rating 2
• 60,000 – 79,999 = star rating 1.5
• 40,000 – 59,999 = star rating 1
• 39,999 and under = star rating 0.5
