Periodically clear debris from the diffuser to maintain performance — there are no consumable parts to replace.

Bubbletech Airprax Tubing

Q: How much Airprax do I need?

Multiply 2.5 LPM per metre by your diffuser length, or divide your total required air flow by 2.5 LPM per metre to get the length of tubing needed.

Q: What bubble size does it produce?

Under 0.5 mm, from around 60,000 laser-made micro-perforations per metre.

Q: What blower pressure do I need?

0.35 bar working pressure at the diffuser, plus enough to overcome the water depth it is set at — a low-pressure blower or compressor is sufficient.

Q: Do I need to soak it before use?

Yes — soak new diffusers in water for a few hours so the microbubbles form as intended.

Q: How does it differ from Oxyprax and the Colorite Aero-Tube range?

Airprax is built for blower and compressor air at 0.35 bar, Oxyprax is the pressurised-gas version at 1 bar for oxygen, ozone and CO2, and Colorite Aero-Tube is a coarser leaky-hose product for blower air at 1 PSI.

Q: What lengths is it supplied in?

1 metre lengths or 50 metre rolls — contact Fresh By Design for pricing and other lengths.
