Calcium scale and biofilm gradually block the ceramic pores; soak the diffuser in a dilute acid bath, then rinse thoroughly before returning it to service.

Angel Aqua Flat Ceramic Oxygen Diffuser

Q: How many diffusers do I need?

Divide your total oxygen flow in LPM by the per-diffuser rate – 2 LPM for the DY101CF-E, 4 LPM for the DY101CF-C or 8 LPM for the DY101CF-A – and round up.

Q: What pressure is required to run it?

It operates between 1 and 2.5 kg/cm2 (14.2 to 35.5 PSI), so it needs a regulated high-pressure oxygen supply rather than a low-pressure blower.

Q: Does it suit pure oxygen or air service?

It is built for pure oxygen from cylinders, bulk supply or a high-pressure oxygen generator; a standard air blower will not reach its working pressure.

Q: Why choose the flat type over the cylinder type?

The flat profile minimises bubble coalescence, so oxygen is distributed more evenly across the diffuser face.

Q: How does ceramic compare with a rubber membrane diffuser?

Ceramic gives far finer bubbles – 100 to 400 microns against 1 to 3 mm for a membrane disc – for better transfer, while membrane discs move much more air at low pressure.

Q: What oxygen transfer efficiency can I expect?

Approximately 40% at 1 metre water depth, with deeper water giving longer bubble contact time and better transfer.

A flat fine-pore ceramic diffuser for dissolving pure oxygen into tanks and holding systems, shaped to spread bubbles evenly across its surface.

Product Information

Key Features

Flat fine-pore ceramic diffuser for high-pressure oxygen — cylinders, bulk oxygen supply or high-pressure oxygen generators
Flat profile reduces bubble coalescence, giving more even oxygen distribution than round diffusers
Fine bubbles of 100–400 microns for a high gas-to-water surface area
Approximately 40% oxygen transfer efficiency at 1 metre water depth
6 mm barb fitting that screws into a 1/4″ BSP female fitting for a secure connection
Suited to transport tanks, fish grading and harvesting, and emergency oxygen supply
Operating range 1 to 2.5 kg/cm² (14.2–35.5 PSI)
Sizing — divide your total oxygen flow by the per-diffuser flow rate below (2, 4 or 8 LPM) to get the number of diffusers required.
