We’re in the lab in almost any day of the week (not weekends).
We’ve all experienced stubborn dust which are a chore to clean – on grilles, corners of the room and even the keys of our keyboards. The suction of vacuum cleaners just may not be strong enough to dislodge these stubborn dust particles, where high pressure air jets may just do the trick. But its limitation? A whole room full of suspended dust particles which will not be healthy or sightly at all!
Our design mechanism works on incorporating both concepts. A compressor supplies compressed air of high pressure to be blown onto the cleaning area to release the dust particles, while a vacuum automatically sucks up the suspended dust particles so they will not remain in the air. How will they be married? Through the use of novel nozzle designs – consisting of both an air jet outlet and vacuum inlet. This is where our group name – concentric, comes into play. Imagine – two concentric tubes, where the inner smaller one supplies high pressure air, and the surrounding space is attached to a vacuum. Pulsed to optimise air flow and minimise turbulence, our “blowing and sucking” design may just do the trick in revolutionalising household cleaning.
