Fine Bubble Tube Diffuser
Fine bubble tube diffuser uses its latest membrane materials, which provide outstanding chemical and fouling resistance. The membrane technology are manufactured with quality EDPM material and comes with two types of perforation: coarse-bubble or fine. Supporting tubes (ABS or PVC material) can be reused when membranes are replaced. The channel pipe is resistant to folding (flexure) tears along the perforation lines. The membrane are fitted over the channeled support pipe, so its nearly impossible to crease.
