In a FIR filter the ratio between the bandwidth and the sampling frequency is costant? I mean, if I use the same coefficients but with the double Fs, will I have also double BW?

Yes, the filter characteristics are normalised with respect to the sample rate, so if you double the sample rate then every frequency parameter for the filter such as cut-off points, bandwidth, etc, will also be doubled.
