FBT Series Ceramic Tubular Fine Bubble Diffusers

The FBT Series Ceramic Tubular Fine Bubble Diffusers provide many of the same performance advantages offered with the Ceramic Dome Diffuser. They are capable of delivering a curtain of diffused gas in the treatment basin as opposed to the plume shape provided by its dome-shaped counterpart. Many applications necessitate the gas transfer flow to

be delivered is with this type of pattern. Different configurations of how much agitation is required as well as many other variables. The FBT Series Tubular Ceramic Fine Bubble Diffuser is capable of delivering up to 4 CFM. Different porosity ceramic tubes are available to meet the needs of a variety of applications. The FBT Series Diffuser is comprises of four simple components---a 3/4 NPT threaded 304 or 316 series stainless steel inlet, the ceramic diffuser tube, an end cap and a tie rod assembly.

The gas is introduced to the diffuser through a fitting connected to the header assembly and slightly pressurized the chamber within the ceramic tube. The gas permeates through the ceramic diffuser body with the fine bubbles being formed by the porous structure of the material and the surface tension of the liquid on the surface tension of the liquid on the exterior of the ceramic tube. The constant flow of fine bubbles then rise from the diffusers to the surface in a constant stream.


The FBT Series Ceramic Tubular Diffuser delivers a curtain of diffused gas in the treatment basin as opposed to the
plume-shaped configuration provided by its dome-shaped counterparts. It is capable of delivering up to 4 CFM.
