The Point Four microbubble oxygen diffuser produces a cloud of extremely fine bubbles – 100 to 500 microns. This is much finer than graphite or carborundum diffusers porous hose and because the diffuser is flat, the bubbles do not coalesce as with circular section diffusers.
The Point Four diffuser uses an ultra fine pore ceramic plate which ensures uniform bubbles across its entire surface. The ceramic is a clean and inert material
One of the simplest ways to dissolve gases, such as oxygen or carbon dioxide, in water is to introduce the gas as small bubbles – the smaller the bubbles the more efficient the absorption of the gas. These aquaculture-duty diffusers are among the most efficient diffusers available, allowing you to increase yield while controlling the cost of expensive gases. Made from premium materials and subject to rigorous testing, Micro Bubble Diffusers provide the kind of performance and reliability our reputation is built on.
Point Four diffusers use a specially developed, ultra fine pore ceramic plate that produces a cloud of extremely fine bubbles of approximately 100–500 microns; far superior to airstones, porous hose or membrane type designs. The flat plate design ensures uniform bubbles across the entire surface and minimizes bubble coalescence to achieve an absorption rate in excess of 80%, depending on depth and flowrate. Bubbling Pressure is 25 to 35 psi. (1.7 to 2.4 bar).
