Carbon cloth offers highest flow rates

Charcoal Cloth International (CCi), a subsidiary of Chemviron Carbon, has developed a new, high-performance filter medium, Zorflex HF, which has highest flow rates to date for any activated carbon cloth medium.

The carbon cloth, which is designed for use in dynamic filtration, adsorption and separation processes, combines high purity filtration and fast adsorption capacity with lower reduction of air or fluid pressure (pressure drop) and resultant higher flow rates. Before the launch of Zorflex HF filter media, activated carbon cloths were considered too restrictive in dynamic airflow applications, as air pressure dropped sharply when passed through the cloth, CCi says,

Activated carbon cloth is re-usable and offers a long service life. It can be easily regenerated by passing a direct electrical current through the fabric to remove deposits.

"With the new Zorflex HF filter media, we're delighted to bring the higher filtration performance and faster adsorption benefits of Zorflex activated carbon cloth into areas demanding higher flow rates and lower pressure drop," said CCi marketing manager, Mark Oberholzer.

CCi can modify Zorflex cloth with various weaves and widths that can be cut, slit and laminated to a range of textiles to be made into products including bag, pleated or disc filters.

Zorflex HF is available in two grades - a standard version, Zorflex HF10, and Zorflex HF70 for even higher adsorption capacity.
