What Is A High Flow Carbon Block Filter?
FiltEdge’s high flow carbon block filter is a 4.5-inch OD filter cartridge designed to address high flow and pressure sensitive filtration systems. Relying on advanced sintering technology and progressive porous structure, High flow carbon block filters have a wider filtration surface area and extremely low water flow resistance compared to ordinary carbon filters. They can not only adsorb impurities in your liquid, but also cope with continuous, high load filtration scenarios, such as commercial water purification and Pre RO systems.
Classification Of High Flow Carbon Block Filters
FiltEdge not only has multiple High Flow Carbon Block Filters, but also can customize filters for you.
Compact, suitable for light commercial use, such as small and medium-sized catering terminals and villa front facing.
Doubling the filtration area, specifically designed for medium to large commercial water purification and Pre RO systems.
Deep purification provides higher physical interception and catalytic adsorption accuracy.
The water resistance is smaller and the pressure drop is extremely low, which can ensure excellent chlorine removal effect while maintaining flow rate.
Advantages Of High Flow Carbon Block Filter
FiltEdge relies on advanced sintering technology to provide you with high flow carbon block filters, ensuring the water quality of your filtration system and reducing your operating costs.
A 10 inch high flow carbon block filter can reach a flow rate of 3-5 GPM, and a 20 inch high flow carbon block filter can reach 7-10 GPM, ensuring your continuous water supply.
At rated flow rate, the initial pressure drop is ≤ 2-4 psi, reducing the operating burden of your high-pressure pump and extending the lifespan of your equipment.
Large capacity adsorption, residual chlorine removal rate>95%, eliminating oxidative damage to the post RO reverse osmosis membrane caused by residual chlorine.
It has strong microporous catalytic adsorption ability for volatile organic compounds and total organic carbon, purifying invisible chemical pollution in water for you.
The high flow carbon block filter adopts a “gradient pore size” sintering process with outer sparsity and inner density, which increases the pollutant holding capacity by more than 30% and reduces your core replacement frequency.
Strictly following the internationally recognized 10 “/20” Big Blue industry standard size specifications for design, compatible with mainstream standard fat filter bottles on the market, reducing your consumable costs.
The High flow carbon block filter uses High purity Coconut Shell Charcoal and food grade polymer hot melt adhesive.
Carbon rod integrated molding, no dust falling, rejecting secondary pollution.
Application Of High Flow Carbon Block Filter
The High Flow Carbon Block Filter is widely used and can provide multiple solutions for water treatment in your industry.
The High Flow Carbon Block Filter can be used as a pretreatment to intercept impurities in the water flow, protect the RO membrane, and extend the lifespan of the RO system.
Widely used in business offices, hotels, hospitals, and central water boiler systems.
Efficiently removes odors, residual chlorine, and VOCs from water, suitable for use in milk tea shops, cafes, restaurants, and food processing lines.
Can be applied to villa underfloor heating, water heaters, etc., as the POE front core of villas.
Single or multi-stage filtration systems for various household and terminal usage points provide pure purification guarantee for the inlet pipeline.
Suitable for community direct drinking water stations, small water plants, or municipal water quality secondary upgrading and renovation.

Mainly relying on the adsorption properties and sintering process of activated carbon in the High Flow Carbon Block Filter. The increased surface area and porous structure of activated carbon after sintering are beneficial for adsorbing odors; The catalytic active sites on the surface of carbon will undergo chemical reduction reactions with free residual chlorine in water, converting chloride ions into harmless ions.
The replacement cycle is usually 6-12 months, and it actually depends on the usage of the filter element. If the water flow rate of the system significantly decreases or chlorine penetration is detected, the high flow carbon block filter should be replaced.
High flow carbon block filter is suitable for standard 10 “/20” Big Blue Housing.
