Exaclty, that's the whole purpose of a holding tank. Still need a regulator/moisture trap when using a compressor with a holding chamber.....if you happen to be a scuba diver, you can use a scuba tank too. You'll just need to have it refilled when air is depleting. There's also little attachments sold around if you want to use a tire....yep, a tire...but the air that comes out is really stagnant. Stinks to high heaven!! lol
