Many consumers believe that children are the same product, pressure delivery when positive pressure blower and exhaust fan exhaust fan fire effect is very similar to using a fan, that the two products can be used interchangeably, then this idea right? Next, we will look at it together. Exhaust fan main role is to discharge smoke at the scene of the fire just happened, when the temperature was 70 degrees when opened, were forced to shut down 280 degrees. Positive pressure blower mainly to the corridor air fans, air corridor to escape at the time of the accident, so more conducive to escape, while a positive pressure in the supply air corridor, that corridor pressure than the other Local smoke will not cause suffocation infiltrated in order to ensure safety. Exhaust fan is carried out in case of fire smoke, transporting gas is 280 degrees; positive pressure blower transport is mainly fresh outdoor air, the gas temperature shows that both transport different, so their structures are not the same. Now Blower motors are generally used temperature is 80 degrees, positive pressure blower can be used directly, but exhaust fan can not be used directly. Positive pressure blower exhaust fan main difference is that, I believe we have some understanding, we must make the right choice, for it to play to give the corresponding performance to improve work efficiency, provide us with a safe living environment.
