Abstract

PURPOSE: To supply a pressure uniformly to increase dissolved oxygen in quantity in all regions of the fish farm, by connecting a proper number of diffusion cylinders by a connection tube and proving said cylinders with many narrow holes, and by combining said cylinders in various forms such as the linear form and the ring form.
CONSTITUTION: A proper number of diffusion cylinders 3, 3'... provided with many narrow holes 2, 2'... are connected by connection tubes 4, 4'... and can be combined into various forms such as the linear form and the ring form, and connection holes 6 to air compressor 5 are provided in proper positions of connection tubes 4, 4'..., thus forming diffuser main body 1. In this case, the form of main body 1 can be changed according to the scale of the fish farm, and air of uniform pressure can be supplied to diffusion cylinders 3, 3'... because subtank 7 is provided between main body 1 and air compressor 5 to connect branching tubes 8, 8'... from subtank 7 to main body 1.
