Introducing a new technology for liquid filter cartridges!

4.5 “ OD (CLIMB™ FILTER) ---
BCFW CLIMB™ filter machines can produce the standard 2.5” filter. The 4.5” (aka “Big Blue”) which is pictured above, was produced on our BCFW machine. Our BCFW machines can produce melt blown cartridge filters with carbon located at any point within or throughout the entire filter using CLIMB™ technology.

CLIMB™ filter technology is a Patent Pending process for infusing layers of Granulated Activated Carbon (GAC) into melt blown filter cartridges. Now you can have all the advantages of polypropylene gradient filter with the chlorine removal offered by activated carbon! CLIMB™ technology creates a filter that has discrete layers of melt blown with alternating layers of carbon. The carbon can be introduced into the filter at any stage of the winding process or in areas of the filter where desired. The amount of melt blown separating the carbon and the amount of carbon separating the melt blown can be increased or decreased with state-of-the-art recipe driven software. The carbon is accurately metered and secured between the layers of melt blown. This method of filter manufacturing creates a filter with very high flow rates, minimal pressure drop, and high filtration efficiency. The result of this manufacturing process is a melt blown gradient density filter cartridge containing carbon with an extremely high carbon surface area with very low initial pressure drops. It eliminates the problems of fouling and face-loading of extruded carbon block filters. By having several layers of melt blown near the center or core, it also eliminates the need for pre-wetting or washing carbon fines from the filter prior to use. |
CLIMB™ filters can be heavily saturated with carbon to the point where the melt blown fibers make up only a small fraction of the total filter weight. CLIMB™ Technology was developed by PMI America, Inc. in Braselton GA.
CLIMB™ LAYERS DECONSTRUCTED
The CLIMB™ process creates discretely metered layers of melt blown and discretely metered layers of carbon within each full stroke of the machine.

CLIMB™ CARBON LAYERS ---
Granulated Activated Carbon (GAC) is infused into the polypropylene (PP) Melt Blown layers and permanently adheres to the PP fibers. The GAC is uniformly disbursed and will not migrate.

CLIMB™ Technology Up Close
The images here are from our digital microscope. As you can see from the first image, the carbon particles are uniformly disbursed and evenly coat the PP fibers. Having the appearance of “barbed wire” the carbon particles can be seen attached to the exterior surface of the fibers.
CLIMB™ filters offer higher surface area and greater void volume than carbon block filters. The result is a depth filter that has a minimal initial pressure drop, high flow rates, and long life.
The CLIMB™process exposes more of the GAC surface area than other types of carbon filters by creating space and open area. The particles do not clump together or migrate, so less carbon can be used to achieve the same chlorine removal as extruded carbon block filters.
A typical carbon block filter will contain upwards of 900 grams of carbon, compared to a CLIMB™ filter containing 80 grams.

GAC INFUSION
The fibers in the photo above are approximately 3-5 microns in diameter and are completely coated with carbon nano-particles. Miles of surface area is created with only a few grams of material.

The VARIABLE ADD-ON
The CLIMB process is variable and can completely coat the PP fibers, or it can be limited to only partially coating the fibers. The photo above shows the uniformity of coating even at very low levels.

Competitive Product
The photo above is from a competitive product claiming to have carbon in the melt blown filter. As you can see, all of the carbon is contained within the PP fibers leaving none of the carbon exposed. These filters are totally ineffective.
