How does gas phase filtration system work ?

The process of gas phase filtration is simple. The contaminated air first passes through pre-filters which trap the suspended particles, and then through the required chemical media beds, which chemically destroy or retain any remaining gaseous impurities. The chemical media can be activated carbon and / or activated alumina impregnated with proprietary chemicals, used alone or in combination – depending on the types and concentrations of the impurities present in air stream. Ecoscrub Systems are designed to operate and maintain contaminant gas levels at 1 ppb (parts per billion) or less.

Range

Bry-Air offers various type of gas phase filtration systems depending on the method of purification and known parameters related to airflow, types and concentrations of impurities present in air, space availability and desired media life, the following systems can be selected:

Deep Bed Systems

Essentially consist of either single or multiple, perforated hollow housing(s), also called bed(s) filled with chemical media, of at least 305 mm (12” or 1’) thickness. These beds are placed perpendicular to the direction of flow of air. Deep bed systems are used for ‘pressurization’ applications in Industry, wherein level of air borne contamination is very high and good quantity of media holding is a necessity for prolonged uninterrupted use, before media gets completely spent and replacement becomes inevitable. Deep bed systems are powered units of horizontal configuration.

Thin Bed Systems

Consist of either single or multiple stages of hollow, perforated, retractable ‘V’- shaped module(s), also known as cassette(s) filled with chemical media, of either 25 mm (1”) or 75 mm (3”) thickness. These cassettes are placed in the path of airflow. The other major parts include a set of pre-filters, final filters, fan/blower assembly and control panel, other than pressure-drop measuring gauges. Thin Bed Systems are used for ‘re-circulation’ applications in Commercial / Industrial sector, as well as for ‘pressurization’ in industrial environments where air contamination levels are on the lower side. Media holding capacity and pressure drops are smaller than Deep Bed units, in this case. Thin Bed systems can be powered as well as un-powered units of both horizontal and vertical configurations.
