2) because it's hard to fill an airplane tire with a vacuum pump - prior to this, they used a 12v air compressor I sent them (which got stolen)
3) that said, volume and the need for oil in a vacuum pump. they do use the air compressor to create suction.
4) weight - again.
5) few parts? on the vacuum pump are fletches - each of those can wear, so I'm not sure where you get fewer parts.... two pistons, two reed valves is this air compressor.
but even if you disagree... go back to number 1. and if next week the dentist gets a brilliant idea for a vacuum pump compressor - I'll build that too.
