A good house ceiling fan needs about 300mm space between the ceiling and the blades. The Arlec would have 200 mm because the small motor and the blade design does not require more. The short down rod would have sent a very BIG signal to me and the electrician should have known that and questioned your product choice. Beware of people telling you to choose a fan with longer blades, bigger fans require a greater space between the blades and ceiling and are more suited to higher ceilings. Longer blades also generate more noise due to the blade's higher tip speed. Fans also need an open lower swept boundary layer for peak circulation cooling efficiency because that is where the coldest air is. Having a fan sitting over furniture is less efficient than having it sit over an open area. Always give any fan its best opportunity to perform well. BigAss fans are superbly designed to aeronautic principles and are highly efficient and economical. The large BigAss fans in Bunnings incorporate numerous aerodynamic narrow blades that add to the swept solidity ratio without increasing drag whereas wide blades have greater surface air flow separation (pressure drag). The winglets that you will also see at the end of the aerofoils are there to reduce bleed and parasitic vortex drag. I am sure that you have seen passenger jets also fitted with winglets, they are fitted for the same reason. If you see a fan with multiple narrow blades and winglets, it has been designed for engineered excellence rather than point of sale appeal like fans with wooden rattan blades are. Fans are bought to serve a purpose and if you want good function, you have to be prepared to invest more to buy engineered quality. I personally like the BigAss Haiku range, not only for their efficiency but also because they are a modern stylish feature, not just an attachment. 3in1 Supadiverta.
