Spectrum filtration granular media consist of media from Purafil & Kalimati generally spherical, porous pellets formed from activated carbon to provide an enhanced removal capacity for acid gases and other corrosive contaminants in industrial environments.

Activated carbon is an effective material for air filtration, as it can adsorb a wide variety of contaminants from the air. Coconut and charcoal are two common types of activated carbon used by Spectrum. Activated carbon is commonly used in gas filtration because of its ability to adsorb a wide range of gases and vapors. Gas filtration is essential in many industries to remove impurities and pollutants from gases before they are released into the environment or used in production processes.
 
 The use of activated carbon in gas filtration involves passing the gas stream through a bed of activated carbon, where the pollutants are adsorbed onto the surface of the carbon. Activated carbon is highly porous, and its surface area can be as high as 1500 square meters per gram, which makes it an excellent adsorbent material.

Spectrum Carb V-250 is designed to provide high gas adsorbing nature and odour control at high concentration levels. The unique 3 layer filter media comprised of activated carbon sandwiched between two layers of synthetic media which act as a barrier in removing toxic gases. The filter possesses high adsorption capacity due to less adhesive shielding.

Spectra Carbon - Pleated is designed to provide high gas adsorbing nature and odour control at high concentration levels. The unique filter media composed of layers of activated carbon structures which act as a barrier in removing toxic gases. 3-layer activated carbon non woven filter material with high adsorption capacity at targeted basis weight.
