Recommended Hand Dryers and Energy / Cost Comparisons:
The table below shows the recommended hand dryers we put forward to the school. Some of the recommendations are based on the quiet noise level produced by the hand dryer as it has been found that young children may have a fear of using loud hand dryers. Some of the hand dryers recommended are also adjustable, hence the variation in figures. The adjustable features include heater element disengagement and motor speed reduction.
