Media

 

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. PreMark's technical support team and wide range of media products guarantee your gas phase filtration requirements will be met.

 

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 Pro Guard 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.
 
Pro guard 300: has proprietary chemistry, along with potassium permanganate, that sets a higher standard for acid gas removal capacity.


Blend

Pro guard Blend: combines Pro guard 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 Pro guard 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

Pro guard 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 Pro guard 400 adsorption and chemical reaction process are chlorine and chlorine dioxide. It is very specific.


 

Plain Activated Carbon

Pro guard 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 Pro guard 600 adsorption process are: cigarette smoke, VOCs, acetic acid, chlorine, methyl alcohol, ozone, and toluene.


 

Pelletized Carbon

Pro guard 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 Pro guard 700 adsorption process are: acetic acid, alcohols, and VOCs (benzene, chlorine, garlic, onion, gasoline, ozone, phenol and tobacco smoke).


 

Impregnated Carbon

Pro guard 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 Pro guard 800 absorption and chemical reaction process are ammonia (NH3) and low molecular weight amines.

Pro guard 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 Pro guard 900 chemisorbing 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).
