Fading text, from top to bottom

I’m looking for a way where I can fade text with a sweeping effect from the top to the bottom. Go to Ohrbits section “Service” to see exactly what I mean.

I tried dividing my text into different sections and then fading them individually with a slight delay for each one using the timeline. This didn’t work that good so my guess is that they’ve done it using some other method. Can someone point me in the right direction here?

Thanks in advance!
