It will run a sprayer, but not very well, you will have to make a "T" to feed into a large truck type tyre so that you have a large reserve of air at no more than about 40PSI. This will give about 10 mins of spraying before you have to wait for the tyre to pump up again.
We have also used a type of sprayer where the air is going through the sprayer all the time, but the airflow was slightly too low to get a good result.
