Activated Carbon Media Basics

Activated carbon is a porous material with high surface to volume ratio, and is ideal for chemical pollutant removal. It can be made from raw materials that include coconut shell, coal, wood, bamboo, or palm nuts.

Factors to consider in selecting which type of carbon to use include cost, activation level, pore size range, hardness / dusting and functional group.

Adsorbent Options

• Aerolace with high activity coconut carbon is used for organic gases such as toluene, PMEA, benzene, etc.

• Aerolace with impregnated activated carbon (acid or alkaline) neutralizes the target gas by causing a chemical reaction between the chemical impregnate and gas.

• Aerolace with in exchange resin (cation or anion exchanger) removes alkaline and acid gases, respectively.

• Aerolace with potassium permanganate mpregnated aluminum oxide nullifies formaldehyde and organic acids, and other gases, through oxidation.

• Aerolace process impregnates any functional granule between 20 and 60 mesh that can withstand a curing temperature of 15°C.


How Aerolace Activated Carbon Media is Different

Aerolace technology uses an aerodynamic process to simultaneously integrate proprietary fiber, and granular activated carbon, to form a homogeneous filter media.

As granule and fiber join to form a sheet of filter media, air passages develop between adjacent granules. The Aerolace process ensures that these air passages are small and uniform, maximizing the residence time of chemical molecules in the filter media, and the opportunity for adsorption.

Aerolace media is adhesive-free, leaving the external surface area of the activated carbon unobstructed. It is also reagent-free, and will not prematurely react with chemicals embedded within the media.

Aerolace has a flexible microstructure: the patented manufacturing process allows the Aerolace structure to be tailored to the converting and performance requirements of your filter.

Manufacturing Flexibility
Aerolace production technology is compatible with numerous materials, including activated carbon, ion exchange resin beads, activated alumina impregnated with potassium permanganate, and zeolite.

Aerolace particle sizes are 10 to 80 mesh. Particle loading ranges from 100 g/m
2 to 1500 g/m2 in one pass. The homogeneous structure cannot separate into layers. Other manufacturing features include:

  • Standard with edge sealing to allow for cleaner converting process.
  • Media structure may be adjusted to accommodate permeability, pleatability, and other converting requirements.
  • Can be produced with blended materials.
  • May be laminated with other materials, such as melt blown or triboelectric particle media.


HVAC filters
The innovative, controllable microstructure of Aerolace media delivers high
efficiencies for applications involving AMC concentrations in ppb.
IAQ filters
Aerolace media can be chemically impregnated to remove most harmful gases as well as particulate.
Automobile cabin filters
The controllable microstructure of Aerolace media makes it ideal for low pressure drop applications.
Respirator filter
Aerolace activated carbon media is ideally suited for respirators and disposable facemasks, where removal of nuisance odors, paint fumes and light industrial gasses is required. Aerolace media can also be chemically impregnated to remove gases that are not easily physically adsorbed.
Water filters
Aerolace media can be rolled to form a low resistance, high efficiency water filter. It is particularly suited to non-powered applications. Because carbon's active surface area is not obstructed by resin binders, filtration efficiency is optimized.
