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.
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).
• 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.
Applications for micro-bubble diffusers include pure gas applications (pure oxygen, carbon dioxide), high-density hauling, holding/grow out tanks and emergency aeration.
Note: Diffusers are also known as airstones.
The Point Four Tracker is one of the most reliable, most respected TGP meters on the market. Gas saturation issues can cause many problems in aquaculture systems that typically go unnoticed. This meter allows you to solve the problems and easily identify issues. The assembly includes the meter, probe, 5 meter cable, charger, USB Cable, and carrying pouch. This meter ships free within the US.
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.
Inox stainless steel cartridges from SPECTRUM are the most durable range of cartridges available. 316L stainless steel meshes are resilient in the toughest of fluid environments of high pressure, temperature and aggressive chemicals and when used for solid particle removal, they benefit from being reusable after a cleaning process.Premier cartridges utilise the ultimate in material and construction technology to create a fully TIG welded cartridge capable of performance in environments where pressure differentials of 5 bar at temperatures up to 360°C exist.Features & Information
Constructed from all 316L FDA approved stainless steel, the pleated woven media, support core and fitting are TIG (Tungsten Inert Gas) welded to introduce no other materials
Higher dirt-holding capacity than the standard pleated range
The PPS can be cleaned by means of reverse flow, chemical, ultrasonic and high temperature burn-out
PPS make an economical alternative to conventional polymeric cartridges where environmental issues prevent disposal
Operating in conditions at up to 300°C and 25 bar differential pressure, these cartridges have the greatest tolerance of the range
Each cartridge is integrity tested by bubble point in IPA (Isopropyl Alcohol) with data provided at despatch, together with a unique identification number
Applications & Industries
High viscosity, such as gelatine
Magnetic coatings
High temperature specification
Caustic fluids
Petrochemicals
Corrosive liquids and gases
Chemical solutions
Straining
These smart PRISM systems have been conveniently pre-assembled for easy and quick installation. Costing less than the sum of their individual components combined, the core filter housing systems are anything but economic and are available in 10" and 20" Regular and Large Diameter sizes, with the unique option to select system sump colour. Coming complete with inlet and outlet gauges to monitor and maximise cartridge life, a spanner to assist with sump removal when performing maintenance and cartridge replacement and connectors to configure the 1/4"-1" port sizes with the most common pipework, the extensive combinations in this range provide endless options for applications and flow rates. Filtration systems are tailored to suit individual applications dependant on the level of filtration required. Single housings provide an effective one stage process, used to target specific contaminants for example, bulk solids, sediment or organics. Two-stage systems are implemented when an expensive secondary filter, such as a fine filtration or water treatment cartridge, benefits from prefiltration, prolonging service life. If applications demand a full filtration cascade, a three-stage system is recommended, which delivers a spatial and economic solution.
Utilising a traditional single layer manufacturing method, the PRISM range of bags offers the greatest option in terms of filtration media and neck seal type, providing a suitable solution for most bulk solid removal applications. PRISM polypropylene and polyethylene felt bags also benefit from an all welded seam construction, meaning they are capable of holding several kg's whilst maintaining filter integrity. Heavy duty handles make changeouts simple, avoiding operator contact with the unwanted filtrate.
