Air Purifier Filtration Media: Chemical, Odour and Corrosive Gas Removal

The right media for your facility should be selected based on the contaminant gases present, concentration levels, airflow requirements, environmental concerns and room design considerations.

 

Potassium Permanganate on Alumina (KMnO4)

ProGuard 100 removes destructive and odorous gases from air streams. It is typically used in air filtration systems in refrigerators, laboratories, offices and homes. Common contaminants removed by the ProGuard 100 adsorption and chemical reaction process are: ethylene, nitric oxide, formaldehyde and other VOCs. Contaminant molecules are small and removal by-products are typically carbon dioxide.

ProGuard 200 removes toxic, corrosive and odorous gases from air streams. It is typically used in HVAC systems at refineries, steel mills, wastewater treatment plants, hospitals, museums, commercial buildings and labs. Common contaminants removed by the ProGuard 200 adsorption and chemical reaction process are: hydrogen sulfide, sulfur dioxide, nitric oxide and formaldehyde. This media has higher porosity to enable space to be found to store solid by-products of reaction. This media is low dust.

ProGuard 300 is an advanced formulation of chemistry impregnated on alumina that is higher capacity than standard ProGuard 200. This new chemistry provides exceptional protection of sensitive electronic equipment for a longer period. The long life reduces labor for replacing media by extending change out intervals. This new media is due to be launched in July of 2004.

Blend

ProGuard Blend combines ProGuard 200 with carbon for general odor control over the greatest range of gases. It is typically used in updating commercial HVAC systems when multiple contaminants are present and often only a single stage is available. Common contaminants removed by the ProGuard Blend adsorption and chemical reaction process are: hydrogen sulfide, sulfur dioxide, nitric acid, formaldehyde, acetic acid, alcohols and VOCs like benzene, chlorine, garlic, onion, gasoline, ozone, phenol and tobacco smoke. This media is a very popular 'broad spectrum' blend.

Impregnated Alumina

ProGuard 400 removes chlorine contaminants from air streams. It is routinely used in HVAC systems in chemical, drinking water and wastewater treatment, and bleach plants. Contaminants removed by the ProGuard 400 adsorption and chemical reaction process are chlorine and chlorine dioxide. It is very specific.

Plain Activated Carbon

ProGuard 600 is virgin, coconut shell based, granular carbon which removes a broad range of gaseous compounds from the air. It is routinely used in HVAC systems in offices, machine shops, lounges, restaurants and commercial and industrial buildings. Common contaminants removed by the ProGuard 600 adsorption process are: cigarette smoke, VOCs, acetic acid, chlorine, methyl alcohol, ozone, and toluene.

Pelletized Carbon

ProGuard 700 is a coal based carbon that removes a broad range of gaseous compounds from the air. It is routinely used in HVAC systems in offices, machine shops, bars, restaurants and industrial buildings. Common contaminants removed by the ProGuard 700 adsorption process are: acetic acid, alcohols, and VOCs (benzene, chlorine, garlic, onion, gasoline, ozone, phenol and tobacco smoke).

Impregnated Carbon

ProGuard 800 is an acid impregnated carbon and removes base pH gases (8-14 pH) from the air. It removes corrosive gases and is routinely used in HVAC systems in chemical plants, blue print shops, animal labs and zoos. Common contaminants removed by the ProGuard 800 absorption and chemical reaction process are ammonia (NH3) and low molecular weight amines.

ProGuard 900 is an alkali impregnated carbon and removes acid gases (1-7 pH) from the air. It is typically used in HVAC systems in refineries, paper mills, wastewater plants, steel mills, and industrial buildings. It protects computers and people and removes odors. Common contaminants removed by the ProGuard 900 chemisorption process are: hydrogen sulfide, sulfur dioxide, nitric oxides, mercaptans, chlorine.

Desiccant

Dry-208 desiccant replaces any alumina based desiccant media for air or liquid drying. High surface area leads to optimum dehydration and strong physical characteristics result in longer life (sizes 1/16 inches - 1 inch).
