摘要： The diffuser assembly (10) of the present invention includes a first and second diffuser bodies (23, 24) in fluid communication with an air distribution pipe (14). The diffuser assembly (10) further includes a saddle (16) that supports the first diffuser body (23) and the second diffuser body (24). The saddle (16) is connected to the distribution pipe (14) by a hollow core rivet (90). Fluid is forced from the distribution pipe (14) through the hollow core rivet (90) where the fluid passes into the first and second diffuser bodies (23, 24). The fluid exits the first diffuser body (23) through a first diffusion media (35) and exits the second diffuser body (24) through a second diffusion media (36). The first and second diffusion media (35, 36) form the air into fine bubbles that serve to facilitate aeration of the fluid.

摘要： The dual diffuser assembly (10) of the present invention includes a first (23) and second (24) diffuser body in fluid communication with an air distribution pipe (14). The diffuser assembly (10) further includes a saddle (16) that connects the first diffuser body (23) and the second diffuser body (24) to the distribution pipe (14). The fluid received from the distribution pipe (14) passes into the first and second diffuser bodies (23, 24) and exits the first diffuser body (23) through a first diffuser (35) and exits the second diffuser body (24) through a second diffuser (36). The first and second diffusers (35, 36) form the air into fine bubbles that serve to facilitate aeration of the medium.
