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).
Applications for micro-bubble diffusers include pure gas applications (pure oxygen, carbon dioxide), high-density hauling, holding/growout tanks and emergency aeration.
Point Four Plastic Micro Bubble Diffusers (PMBD) are one of 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, PMBDs provide the kind of performance and reliability our reputation is built on.

• Robust construction—ceramic plates set in an injection moulded plastic base with solid brass connection fittings.• Flexible, modular design lets you easily add or subtract diffusers as your needs change.

Note: Diffusers are also known as airstones.
WEDGE-LOCK™ uses an ultra fine pore ceramic producing a high Absorption Efficiency (AE) allowing you to increase yield while controlling the cost of expensive gases
The Point Four WEDGE-LOCK is a modular system of microbubble diffusers and end sets that fit together to form a bank of up to eight units. Oxygenation capacity can be increased (or decreased) as your needs demand by simply changing the number of diffusers used for greater flexibility and minimal downtime.Designed for total ease of use, WEDGE-LOCK™ modules ‘Twist and Lock’ together to form an air-tight seal without the use of tools. Hose with push-in fittings connects the diffuser banks to the gas supply, significantly reducing set-up time and effort.Manufactured from tough plastic, WEDGE-LOCK™ will not corrode and is resistant to the Sun’s ultraviolet rays. The diffuser’s streamlined wedge shape improves stability in tanks with high water flow and offers less resistance in self-cleaning tank systems.
