Hand dryer install

[Stuart Parker]

I have hand dryers to install
Can these be spurred off a ring main circuit
Or do they have to have dedicated circuits
They are 10A units and the ring main only supply computers radios so nothing with a heavy load.

Usually a hand dryer would just be put on the ring circuit using a FCU (Fused Connection Unit) as they are no more onerous a load than a kettle. Of course, having checked it is RCD protected...

You don't say how many dryers you are installing … I have 3 to install on Tuesday, and will be putting in a new circuit, because they will all get used repeatedly at the same time (break time).

4 but they are located in different area so only 1 per circuit

That should be ok with FCU isolator.
As above, RCD protection required on the supply circuit.

Why is RCD protection required on the supply circuit for a hand dryer fed from an FCU, whether from a dedicated circuit or an existing ring? There may be specific instances such as the alteration or addition including a buried cable but otherwise a blanket statement that RCD protection is required is misleading.

Most hand dryers are a waste of time and money imo. They make a lot of noise and do not even dry your hands invariably, unless you have ten minutes spare and manage to activate them consistently. I think the blade dryer is good though having said that. I always recommend paper towels on a radial.

. I always recommend paper towels on a radial.

Now THAT’s a brilliant energy-saving suggestion.

You don't see driers in hospitals they carry germs into the air paper towels more hygienic but costly in longer term

It's to replace hand towels due to covid 19

a bit of science fact by washing you hands and using a hand drier will spread what is on your hands with any spores left over will fly through the air by using paper dry you hands will elimanate the spread of any germ .

Mythbusters did a thing on this. As above paper hand dryers are a lot better.

You've got that backwards, hand dryers should be removed and replaced with paper towels because of covid 19

And so folk wash their hands instead of giving up because there is a queue waiting for the single dryer trying to cover 4 or more hand basins that provide 4-6 toilets and/or urinals (that was put in to replace a single paper towel dispenser)

you see that at motorway stations all the charp on the walls when you use them .

Those dyson ones are the worst, you have to put your hands into the narrow gap and try like hell to not touch either side of it as the jet of air is trying to strip the skin from your hands.

Who said anything about paper towels.
It's a material roll dispenser.

My apologies, in that case my post should say 'you've got that backwards, you should be replacing roller towels with paper towels due to covid 19'

Ok, so I had it slighly wrong.
If you have cleaned your hands properly with soap, then there is no bacteria on your hands once you have finished.

If you don't clean your hands properly then a hand blower is a lot worse than paper hand towels as paper hand towels remove more left over bacteria than blowers and don't blow the bacteria around the surrounding area.

Yes, the blowers do blow water from your hands to the surroundings but it is bacteria free.

Conclusion for this thread: As @davesparks has said, replace roller towel with paper towel.

Only if everybody usimg it has washed their hands properly, but then they still end up creating a warm damp enviroment on the handdryer itself for bacteria to grow in.
Plus all the fluff and junk that gets collected in the air inlet filters allows bacteria to collect and breed there too before being blown out of the nozzle.

Totally agree mate.
I definitely wouldn't be advising anyone to have blower hand dryers now.
I would tell them the truth, that paper towels are a lot better, especially regarding Covid 19.

No wonder England is worst for corona deaths /sigh (idiots abound)

Yeh, I have cleaned a few out it is disgusting what collects inside a hand dryer, worse than kitchen cleaning when you get inside. Also, a lot of hair.
