5.1 Introduction. Fans and blowers provide air for ventilation and industrial process requirements. Fans. generate a pressure to move air (or gases) against a resistance caused by ducts, dampers, or other components in a fan system. The fan rotor receives energy from a rotating shaft. and transmits it to the air.
All types of blow dryers work by sucking in cool air using a fan. This air is then passed over a heating element which heats it to the right temperature. Finally, the hot air is blown out of the nozzle onto your hair.Cheaper blow dryers use a metal coil to heat up the air.Although this does the job, there is one major downside.The heat produced by these metal coiled dryers is very dry and uneven, and they literally boil the water off your hair.This is why regularly using a cheap conventional blow dryer often results in very brittle and dry hair which is prone to breaking easily. Ceramic blow dryers work differently.heaper blow dryers use a metal coil to heat up the air. Although this does the job, there is one major downside.
