Purafil II Chemisorbant Media, 50# Pail

PURAFIL CHEMISORBANT MEDIA (PURAFIL)

Purafil Chemisorbant Media consists of generally spherical, porous pellets formed from a combination of activated alumina and other binders, suitably impregnated with potassium permanganate (KMnO4). The potassium permanganate is applied during pellet formation such that it is uniformly distributed throughout the pellet volume and is completely available for reaction with target gases.

Purafil Chemisorbant Media has been specially engineered to provide an enhanced oxidation potential thus assuring the highest overall performance. The chemisorptive process removes contaminant gases by means of adsorption, absorption, and chemical reaction (oxidation). Harmful gases are trapped within the pellet and converted into harmless solids which remain in the pellet, eliminating the possibility of desorption and release back into the environment.

Purafil Chemisorbant Media demonstrates a higher working capacity for broad-spectrum contaminant control in applications where there are undefined sources such as: outdoor air cleaning, general odor control, and off-gassing from building materials and office furnishings. This media is often used with Purakol media to provide broad-spectrum contaminant control.

Quality Control
Each lot of Purafil Chemisorbant media is thoroughly tested prior to shipment according to the procedures described in Purafil’s ISO 9001 Quality Systems Manual. This testing includes but is not limited to: bulk density, potassium permanganate content, moisture content, crush strength, and abrasion.

Media Life Analysis
Samples of Purafil Chemisorbant media should be sent on a regular basis to the Purafil laboratories for testing to determine remaining media life. This provides for scheduled maintenance, avoids downtime, and assures ongoing protection for processes, products, and personnel.

Disposal
Purafil Chemisorbant media should be disposed of according to local, state, and federal guidelines.

Purafil Chemisorbant media is UL 900 classified for flammability.
