Fine Bubble Tube Diffusers
Fine bubble Tube diffusers can either be connected on one side or in pairs. The connection can be made to rectangular or round tubes (ABS material) with the appropriate adaptor.
Premium EPDM material is used to manufacture the membranes. The bubble perforation can either be fine or coarse.
The support tubes (ABS or PVC material) can be reused when the membrane is replaced.
The units offer maximum performance at minimum cost and require minimum maintenance.
