3. Main objectives: 1. To create smoother flow of air 2. To build a safety home appliance for general usage 3. To reduce the burden in the process of cleaning the fan Other objectives: 1. To create a scented environment 2. To reduce the electricity consumption which leads to energy saving 3. To create a user-friendly product so that it could be commercialized and benefits general consumers 3

4.  "Normal fans chop up the air with the blade, which is very uncomfortable when you are sitting in front of a fan. It buffets you. This is far smoother”, said Sir James Dyson when he unveils his latest invention, The Air Multiplier. (13, 10 2009).

13. 13  Output Voltage = 220 / 240 V  Total Power Consumed = 96 W  Rotational Speed for Fan Motor = 50 / 60 Hz  Rotational Speed for Rotator Motor = 3-4 rpm  Weight = 4 kg  Height = 60 cm

14.  Use more lighter material for upper part (fan frame) – plastics.  Use round shape for fan frame rather than pentagon  Use circular casing for bottom part. 14

15.  The objectives achieved: - Smoother flow of air is created - A safety home appliance for general usage is built - The users are eased during the process of cleaning the fan  Bladeless fan is more efficient and effective than conventional fan. 15
