I have the same compressor. I use it to fill tires, run a brad gun, and blow out my 6 zone sprinkler system every fall. It would probably do many more things, I just don't have a need.
Get a good quality 50 ft rubber air hose and a standard air compressor tools kit and you are good to go, with some assembly required.
The 6 gallon one?
How do you blow out the sprinkler system? Where do you connect it?
All sprinkler systems have a blow out port between the zone valves the backflow preventer valve. Mine is just a T-Pipe connector next to my front door step. It is a 1/2' npt with a nylon plug in it during the summer. In the fall I have a male air adapter that has a reducer on it to go from 3/8" to 1/2" that goes in that T-Connector. I bought all that at the depot for about $10.
All I do is shut the isolation valve (in the crawl space so a big pain in the ass to get to) and then cycle one zone to release the water pressure in the system. Then I take out the plug and put in the adapter, set the pressure regulator on my compressor to 30 psi, and plug in the compressor hose to the blow out port. That pressurizes the system. Then I just cycle each zone 1 at a time until I blow water mist out of all of that zone's heads, then I go to the next zone. The compressor runs off and on but works fine. I disconnect the air hose before I shut the last zone off so the pressure bleeds off.
Make sure you set the compressor's regulator to something less than your city water pressure BEFORE you pressurize the system. I don't know what the sprinkler system is rated to in pressure, but I'm sure it wouldn't take the 125 psi that the compressor is set for, at least not for very long.
Takes all of 30 minutes and most of that is standing in the yard watching the system blow out.
Then I put the nylon plug back in and I'm ready for spring
