Hi friend thank you so much for the opportunity to write here :)i'm looking for a solution to make it work in Italy an USA air dryer.The air dryer is compatible with 120V/60hz 15amp, in Italy we use 230V 50HZ. I am looking to design my own frequency converter / circuit even rewinding he motor, Another option is to make it work with an inverter which should still provide the correct voltage & 60Hz frequency sinewave output.
as you can imagine i am looking any way possible to make this air dryer work in italy, i really need his particular model to work in Italy and implement it in my wife air saloon. :D:cool:
Thank you really in advance everybody that give me any support and even willing to work with me on his project
Best regards Andrea

You should use a work site isolation transformer (230-to-115V) to get the right voltage. You'll have to live with the frequency difference which will manifest itself as a slightly slower motor speed (depends on the type of motor actually).

If you can separate the motor from the heater elements you could power the motor using a simple inverter as the power consumption of the motor itself will be quite reasonable.

If this has a Universal motor, (AC/DC) the frequency does not matter.

thank you so much for the repl :D sorry for the late interaction with this forum but I had lost track of the notifications...

about matter of the frequency I think it is very important because I read online that several people have tried a step down transformer but they burned the motor i even wrote an email to support let me paste here what they wrote:
"Our device just won't work outside of a native 120V/60Hz outlet unfortunately! If you try to use it in something like a 230V/50Hz outlet with a step-down converter, there are two things that may happen. The first is that it might display a "P" to indicate an internal power failure and it won't turn on. The second is that it may start up momentarily and the motor will spin so fast that it will burn out and become unusable. Our team has tried many solutions to try to get the device working with different voltages and frequencies, but we haven't found anything yet.

and it is also written in the spec tab of their product

For the last time, your problem is the voltage conversion which is a right pia costly process and not worth the effort.
The frequency change won't be a problem compared to the former.

I call BS on that statement. Either its a conventional motor (which would either work with 'any' frequency or run slower if the motor is the frequency-dependent type) or it's a 'digital' motor in which case the frequency is totally irrelevant as it will be driven electronically.

My impression is that they simply don't want the unit used anywhere except North America. We could easily prove this if you could show pictures of the innards.......

I'm also suspicious of its claim to require 15A from 120V - that's the equivalent of nearly 2kW of heat and you'd 'fry' (or frizzle) anyone under it....

Air saloon...?????
Buy a new one.........locally.
thank you so much sir for your reply, actually this particular hair dryer is on my priority list becouse in my place there are a lot of foreign woman who are looking for this particular hair dryer, becouse none of Italian hair dryer is working for theyr hair texture, so after a survey many new client are willing to join my wife hair saloon for this product

sir thank you so much for your reply, i'm sorry if i write in different forums, my hunger to find a solution lead me to writhe in which i was considering the best electronics community out here, thank you so much for your time, will try to provide the picture as soon as possible .

ok sir noted :D
