Point Four Trac-Lock Diffusers are an economical alternative to the Point Four Micro Bubble Diffusers (MDBs). Like the MDBs, they are good for use with pure oxygen and/or carbon dioxide.
A Simple Design
The ceramic flat plate design ensures bubbles across the entire surface. The slim design will not hinder fish netting and will accommodate most fish transportation systems. The "twist and lock" design allows for easy diffusing area adjustment, or for simple removal of sections for cleaning/servicing. We recommend using a support when locking three or more bases together.
High Absorption Efficiency
Depends on submerged depth, flowrate 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 minimizes rising air bubble coalescence.
Base has a diffusing area of 12.25" L x 2.5" W (31 x 6 cm) and an optimum flow of 6.5 cfm (3 Lpm).
