I find 120 Litres / minute free air flow and 40 litre tank way too low even for just using the air boy air gun ,at 116 psi the air boy uses 260 lmp
When cleaning mowers with 120 lpm it takes far too long ,you have to wait a lot of the time for the compressor to.build up but saying this if time is not an issue this 120 lpm will clean mowers but if you use a 260 lpm compressor the difference is huge when cleaning with the air boy gun.
I use a 230lmp with the air boy gun but really should be using a 300 lpm compressor , that's why the cheap air guns only use 2 to 3 cfm (56.63 lpm to 84.95 lpm ) they are made for smaller compressors .
