Fine Bubble Disc Diffuser

These diffusers are made with compression moulded membranes to specifically increase its precision quotient. As an added benefit of using compression moulded membranes, the tear resistance of the parts is now multi-directional improving durability. The perforations are based on detailed studies in OTE (Oxygen Transfer Efficiency).
