This is the dust collection system I installed in my shop. It uses a 2 HP dust collector installed in a room next to the shop which helps cut down on the noise.
I ran 6″ galvanized pipe to strategic locations by the dust producing tools in the shop. Each tool has its’ own blast gate that can be opened or closed based on which tool is being used.
I also recirculate the conditioned air back into the shop so I don’t lose cool in the summer or heat in the winter.
