Dryden Aqua manufacture the ultimate in flat plate ceramic
gas diffuser. One DAD300 diffuser will supply sufficient oxygen (carbon dioxide,
argon, nitrogen and other gases) to supply 100% of the oxygen demand of approximately 1000
kg of fish with an efficiency approaching 100% transfer of oxygen into solution. In
seawater applications it can actually be difficult to see the bubbles, since the gas goes
almost directly into solution.
The ceramic plate has been designed to be very strong, the
thickness of the ceramic has been increased over the more conventional plates. The pore
size is also only 0.3 microns which produces a cloud of tiny oxygen bubbles in the water.
There is no better oxygen diffusers or gas diffuser available.
The ceramic flat plate diffusers give a very small bubble size and are
used where a small high rate diffuser with a high oxygen transfer efficiency is required.
The working gas pressure is 25 to 35 psi, do not exceed 50psi as it may result in damage
to the diffuser. The DA flat plate ceramic diffusers all have a 1/4" female BSP
female threaded inlet to which can be fitted either a 1/4"or 3/8"hose
adapter. Compression fitting can also be fitted, sizes available at 6/4mm and 8/6mm hose
fittings
