You can do a lot with a simple hammer and a handful of nails, but undoubtedly you can do a whole lot more with some high quality tools. Manpower alone won't get a lot done when it comes to building and demolishing. When you construct great things you need powerful tools.
Air compressors may seem like an expensive toy, but there is nothing like a good German Bostitch compressor or a German Bostitch kompressor as it is called in Dutch to create an instant vacuum, to boost or blow something with a powerful surge of air. What made them stand out from all the other air compressors and caused them to become an instant recommendation is the oil-free operation which is a feature to value in an industrial air compressor.
A regular compressor that operates with oil uses it to fill in all the cavities to ensure air insulation, but after some time the oil inevitably stats leaking through and microscopic parts of oil are not what you want to get on your project parts if you need some compressed air or a total vacuum in there.
Bostitch compressors have also won favor for the great variety they come in. A 20-liter compressor can blow no less than a 100-liter device, but the key point in choosing the right one is the general capacity that you are looking for. And just like an old maxim goes - there is no such thing as too powerful a tool. If you can grant it the necessary power supply (ranging from 110 to 230 V, can be powered through an oil generator) and have the transport for transportation, you should choose a larger model which will save time for it will surely make everything faster. If your priority is a small, but highly efficient device and a compact model that enjoys the same results over a little longer period of time, you may choose a smaller model to perform more precision-oriented tasks.
There is probably just one thing that a good air compressor won't help you build - a sand castle - because it is not a toy, but a powerful tool for construction and installation of some real life no-nonsense formations.
