Activation of smoke purge fan in stair case of residential R2 occupancy. NICET Certification Fire alarms Pop quiz questions...firealarmscertified.com/catego...
These fans are used for large buildings, especially high-rises to literally suck the smoke out if a building were to catch fire so people can exit more safely and fire fighters can see more clearly. The suction power on these is absolutely astounding if you’ve ever seen one in action!
Yea but if power or.fire is so bad wont make difference it will violate it out but fire so big.. all.smoke won't exit in time.it.help.fkr like fire thats not so.big
Most of the whining is coming from the automatic vent opening, you can see it happening through the tube right before the noise stops. You can also see the vent below the fan closing up...
When you're so ready for fire you have a fan to clear out the smoke
It’s a psi fan
Imagine this as a chimney for your kitchen
Who else was lowkey expecting smoke / dust to come out of the fan?

TH-cam recommendations has brought us together once again
School computers when you open word:
They are actually called pressurization fans
Why would they be called so if they push the air out of the building rather than pumping it inside? (Just plain interest, no offence)
@@tituan9152 because they need to pressurize the air to
Force the
Smoke
Out through the exhaust fans
That took some time

What do you mean post fire? What is this for? What fire? Where?

It's a fan that's designed to pull smoke out of the building.
This one is being tested.
That’s a pressurization fan.
looking at the direction the rotor is spinning and the veins of the rotor, it is exhausting the air out.
Noise like a siren 🚨

Paul Grohens I’m guessing is there was a small fire you could clear the smoke like this

Is the motor for the fan BLDC, induction or synchronous?
Most likely induction.
