Charge Modified Filter Cartridges

3M Purification Inc. offers a full line of charge modified depth cartridges (Zeta Plus™ Series) composed of cellulose and diatomaceous earth materials, trapping contaminants smaller than the rated pore size via electrokinetic adsorption.

Zeta Plus™ A Series: Designed for general industrial and utility applications requiring efficient filtration in the 1 - 20µm range.
Zeta Plus™ Activated Carbon Series: Carbon containing cartridges capable of removing trace organics without the cleanup problems associated with bulk activated carbon.
Zeta Plus™ U Series: Designed for high efficiency and cost effective filtration of resins.
Zeta Plus™ U2 & UW Utility Series: Designed for removal of particle contaminants and moisture from dielectric oils. Commonly used in the power generation industry.

Large Diameter Cartridge Systems:

740 Series: 7" diameter, 30" & 40" length cartridges containing high efficiency polypropylene or polyester microfiber media in a unique radial pleat configuration. High dirt holding capabilities designed for use in high contaminant applications (amine, coolant...). Utilizes specially designed housings available in a variety of sizes, materials, and configurations.

High Flow: 7" diameter cartridges containing high efficiency polypropylene microfiber media in a unique radial pleat configuration. Available in 10", 40", and 60" lengths. High flow capability (up to 500 gpm 60" cartridge) makes it ideal for large flow, low contaminant applications (pre-RO, process water...). Utilizes specially designed housings available in a variety of sizes, materials, and configurations. High flow cartridge capability reduces required housing size for a given flow rate optimizing housing foot print and capital costs.

Bag Filter Products:

NB Series: Polypropylene & Polyester felt and Nylon Monofilament nominally rated filter bags providing cost effective filtration for industrial applications.
DuoFLO™ Series: Graded porosity polypropylene & polyester felt media in a unique two cylinder design providing for higher dirt holding capacities and up to five times the life of conventional nominally rated bags. Easily retrofitable for use in bag housing systems.
100 Series: Single layer high efficiency polypropylene microfiber media in a bag configuration. Ideal for oil contamination removal.
500 Series: Multi layer high efficiency polypropylene microfiber media in a unique wrapped bag configuration. High dirt holding capacity allows for much longer life than conventional bags.

Specialty Filter Products:

NanoSHIELD™ Series: Hollow fiber polypropylene media, polyethylene potted cartridge filters designed for critical applications in the electronics industries.

CTG-KLEAN™ Systems: Sealed filter pack system that eliminates direct contact of contaminated filter reducing system clean-up requirements and operator exposure. Available in many filter types and sizes.

Activated Carbon: Polyethylene cartridges containing an activated carbon bed for removal of trace organics in industrial applications.

Metal Filter Cartridges

For those applications where use of reusable metal based cartridge is preferred, 3M Purification Inc. offers the below products:

Auto-Klean™ Series: Metal edge filters capable of filtering highly viscous fluids. Spacing between two metal surfaces determines the degree of filtration. Typical applications include lubricating oils, fuel oils, hydraulic fluids, and greases. Auto-Klean filters cleaned by turning a handle, resulting in solids removal and full flow restoration. Larger capacity Auto-Klean filters available with self cleaning capabilities. Two-stage filtration version of Auto-Klean filters available capable of removing particles down to 37 micron (nominal).

Micro-Screen™: Stainless steel screen mesh elements ideal for corrosive fluids and other fluids that cannot be filtered by fiber type media.

Poro-Klean™: Stainless steel filter elements formed from porous sheets of sintered powdered metal, ideal for high temperature liquids and gases and corrosive fluids.
