Gas Phase Filters

Introduction

Air cleaning through an effective gas phase air filtration system is a way to remove gaseous contaminants from the breathing air. Most gas phase filtration systems use activated carbon to adsorb gaseous molecules.

Application

Activated carbon is a superior adsorbent for food, beverage, agricultural, and pharmaceutical processing applications. The activated carbon filters are used in applications to filter out odour and hazardous gaseous contaminants present in kitchen, industrial, animal house, laboratory exhausts etc. These filters are also effective in controlling the presence of gases or organic vapours.

Media and Its Function

Activated carbon is a porous material consisting mainly of elementary carbon modified to have a large internal surface area. The activated carbon in the form of granules or in the form of impregnated glass fiber media act as an adsorbent. The pores trap the contaminants.

On a microscopic level, activated carbon looks and acts much like a natural sponge, with pores and a vast amount of surface area. As gaseous molecules come into contact with the carbon, they are drawn into the carbon and held into place by a variety of forces.

Construction and Supports

The activated carbon filters are offered in different models to meet the desired air handling capacity. It is offered as flat panel adsorbent filters completely packed with activated carbon granules. The carbon panels can also assembled into a “V” Bank filter to enhance the air handling capacity. Activated carbon impregnated glass fibre media from “Lydall” is used as the filtration media to enhance more quantity of air. This filters can also be assembled in “V” bank form for maximum air handling capacity.
