Could Dyson Bladeless Fan Idea work for CPAP?

[James @ Intus]

You can't have missed this in recent months. Dyson launched a fan without blades.

It's called the Air Multiplier and uses some clever engineering to combine air into a steady stream.

Here's a Telegraph feature on how it works:

And for the TF-like engineers among us, a scientific explanation:

Some embedded video's:





A traditional CPAP is of course much like a fan. It has a blower which pressurises air so it comes out at a pressure higher than that in the room. That keeps your airway open and there you are, good sleep.

I wonder... Could this bladeless fan system be applied to CPAP? Would it make it more quiet? More efficient? Less energy?

Does anyone here have, or has anyone seen this Dyson bladeless fan?

If it could make a difference for CPAP, ResMed or Respironics, if you read this, PM me for my bank account details

I have seen these for sale at a large membership type trade/retail outlet, and whilst they look amazing and i think the Dyson is a genius, the price is astronomical.

A standard 16" fan can be brought for around 30 - 40 pounds, the one of these I saw was over £300

Ho hum!

The same principal has been used in ships since I don't know when to pump bilges and drain ballast tanks. Not to mislead - the bit in the fan where a small volume of air at 55 mph is used to draw in large quantities of surrounding air.

I want to buy one, how???!

They sell these at comet/currys £200 though!

athough bladles they are noisyer than some desktop fans, we had one but returned it as it was no more as powerfull as our 12" £10 quid job from argos,

i think they are mostly for design rather than performance, claiming also to be safer too, they still however use the same princaple of a fan except the fan is actualy in the base,

it has a similar fan to what is already in cpap machines which is mostly known as an impeller, a fan which sucks in air then throws it out at a accelerated rate similar workings to a turbo in a car exept the fuel is electricity not exaust gasses,

most cpap machines use 2 impellers to generate more compressed air at lower motor speeds reducing the noise output, i know resmed already use this technology in there machines, as with some other popular brands,

anyways the same type of proccess of the dyson happens in the cpap machine just at a higher rate, one would need to have a high torque motor spinning more impellers to run more efficently at lower speeds and to allow instaint rpm increase to cope with the vairiable rate of the air flow, i know cpap stands for constaint airway pressure but infact it dosent operate at a constaint pressure it does allow for breathing variations to occur atleast i think it does.

i think hopfully there will be tech available in the not to far future to allow a much quieter approach to cpap, i think much of the noise comes from the mask its self, so perhaps a redesign on the masks venting system would be a good place to start
