Yearly filter maintenance runs $900 per year, per generator (quarterly, semi-annually, annually filter changes). I highly doubt any auto dealer in the US actually uses a near pure nitrogen in their tire filling stations. And nitrogen generators do not push high pressures. We push about 75 psi, but our purpose is not based psi but rather volume of nitrogen.

I imagine most places that offer nitrogen for tires get tanks filled by a gas company. Beverage canning facilities use bulk tank nitrogen delivery/storage for canning non carbonated drinks like ice tea.
