I have Ohmeda Excel 210 machine with ventilator supply power issue

I have Ohmeda Excel 210 machine with ventilator supply power issue, we don’t know the exact voltage that’s why we can’t solve its problem, I think its voltage supply is changed, also ventilator is not working because we install this ventilator on 220V instead of 110V

Technician checked this ventilator and told us that he can’t resolve it unless same ventilator is not here, he will resolve this issue by comparison of both ventilator’s supply and resolve its voltage
