DESCRIPTION

The Coconut Shell Carbon series is made from select grades of high quality coconut shell, activated under rigid process control conditions by high temperature steam activation to yield a strong, dense, very active product designed for vapor phase application.  This product provides high surface area; fine pore structure, high density, high volume activity and ease of regeneration. This carbon has a uniform absorbent profile with well-developed pore structure, allowing for a wide range of absorbate retention.

CAUTION: WET ACTIVATED CARBON DEPLETES OXYGEN FROM AIR.

Whenever workers enter a vessel containing carbon, all precautions must be taken since dangerously low levels of oxygen may be encountered.  Atmosphere sampling and work procedures for potentially low oxygen areas should be followed.
