Spoke with a plumber years ago who said he could use a 2.5 gallon pancake compressor to blow out sprinkler lines and he had a knowing grin when he said it. I got the impression it was one of those " oh well you COULD do it, but there are much better ways". Like if you wanted to travel coast to coast you COULD walk it, but car, bus, rail or flying are all better options.
Sprinkler companies use giant compressors that hold a huge volume of air and they blow out the lines at low pressure….around 40 psi….well below the pvc limits. It is the safest and best way to do it….but they charge you every year and we're on Slickdeals looking to save money.
In order to use this you would have to run this multiple times per sprinkler zone. You'll have to let it fill and then open the zone and open the compressors valve to start the process. The 10 gallons will run out relatively quickly and you'll still have water in the lines. You'll have to close the compressors valve and wait for it to recharge. In 1/3– 1/2 acre yard would estimate you'll have to cycle the compressor at least 4-6 times through EACH zone waiting for it fill each time. It's going to take up a LOT of time.
Harbor Freight has a 20 gallon McGraw compressor that goes on sale periodically for around $230 that would make the job much easier. You might need to use it 2x per zone.
In my neck of the woods sprinkler companies get $60-$80 to blow out a typical 6-8 zone sprinkler system.
If you use it 3-4 years, your savings have paid for the compressor, anything after that is gravy, plus you'll have the compressor should you need it for anything else.

If you mean inground sprinkler system….it is possible, but you're probably not going to want to.

Don't know your line lengths or number of zones, but I purge mine every year with my 8 gallon 1hp Cali air tools compressor with no issue. I have 3 zones on a 1/4 acre property.
It does take two rounds of waiting for the compressor to fill again and then turning the spigot back on to let the air through. Regardless of the PSI that I set, the CFM just isn't there so I just let it go full blast.
Last winter was my 5th year. Not the best sample considering how warm it was, but I have no complaints at the end. Machine paid for itself 3x over

Probably the same here. May have once had them turn on for the spring and noticed it was so easy that I wouldn't pay for it again.
It's a super simple process:
- Close the secondary valve or spigot that is there to avoid water traveling down the line if the main sprinkler shut off valve or spigot should have a slight drip. Typically it's located right next to the main shut off valve.
- Open the main valve or spigot
- Turn your sprinkler timer/clock to ON position
That's it. Your done.
One thing they do at openings is check to make sure all the heads are working, etc. They'll replace heads (for more money) at that time.
With systems over 10-15 years old it's pretty common to have to replace a couple of heads a year.
You can watch YouTube videos and replace them yourself.

You could use this 10gal, it's not as good as professionals but like another comment mentioned, water expansion is minor, if you blow out till most of the water is out you're good. Learn a little about blowing out your system and this pays itself off pretty quickly
Good to know.
It's going to depend on yard size and the length and diameter of the sprinkler lines.
My yard has some long runs.
Even if yards are the same size, the line lengths could be very different depending on how it was run. One example is if sprinkler line was installed under the driveway or not. If not, they had to make longer runs around the entire property.
For me spending the extra $50 for the 20 gallon McGraw one is worth it for the peace of mind, time saving, and higher general usefulness for the compressor.
Understand others may not see it the same way.
