PRODUCT BULLETIN OVC 4x8 Coconut Granular Activated Carbon Description Specifications OVC 4x8 is a granular activated carbon is designed for odor and VOC removal in vapor applications. It is made from select grades of coconut shell that imparts a hardness that is necessary for the long life expected in many applications. Produced under rigidly controlled conditions by high temperature steam activation, OVC 4x8 carbon exhibits high surface area, fine pore structure, high density and high volume activity. The granular shape results in excellent gas distribution properties and allows the carbon bed to operate at lower pressure drops..

Typical Pressure Drop (4x8 Granular) The design of an activated carbon adsorption system is dependent on the adsorbate type, influent concentration, temperature, flow rate,performance objective, relative humidity and other factors. Calgon Carbon can help evaluate the suitability of activated carbon to satisfy specific needs and assist in the design of an adsorption system. In addition to the supply of activated carbon, Calgon Carbon offers adsorption systems and carbon reactivation services to meet particular treatment objectives. When designing a vapor phase activated carbon adsorption system, Calgon Carbon Corporation recommends using the dense-packed pressure drop for fan sizing since activated carbon will settle during use. The loose-packed pressure drop will probably occur during start-up of the system. To determine what is best for your application and assistance with the design please contact Calgon Carbon Corporation by calling 1-800-4-CARBON.

In closed or partially closed containers and vessels, oxygen depletion may reach hazardous levels. If workers are to enter a vessel containing carbon, appropriate sampling and work procedures for potentially low oxygen spaces should be followed, including all applicable federal and state requirements. Please refer to the MSDS for all up to date product safety information.
