Point Four Trac-Lock Diffusers are an economical alternative to the Point Four Micro Bubble Diffusers (MDBs).
A Simple Design
The Point Four Trac-Lock Diffusers are a cost-effective solution for optimising oxygen and carbon dioxide diffusion in aquaculture systems. Featuring a durable ceramic flat plate design, these diffusers ensure even bubble distribution, maximising gas absorption efficiency—up to 100% at depths of 6 meters. The “twist and lock” system allows easy adjustment and cleaning. With a rust-resistant plastic frame and compact design, they integrate seamlessly into fish transportation systems without hindering netting. Ideal for reliable, efficient gas diffusion in aquaculture environments.We recommend using a support when locking three or more bases together.
High Absorption Efficiency
Depends on submerged depth, flow rate and dissolved oxygen concentration. Typically 40% to 50% at 1 m depth; can be as high as 80% or even 100% at depths of 6 m or more.
Features and Benefits
• Plastic frame will not rust or degrade over time.
• Easy to install and use—trouble-free operation.
• Efficient design minimises rising air bubble coalescence.
Base has a diffusing area of 31cm Long x 6 cm Wide and a max flow of 3 LPM
