General Carbon’s Vapor Box Series of carbon adsorbers are versatile high airflow units. Each filter is easily transportable via the fork skids or lifting lugs. The full plenum chamber and large bed surface area in each model allows for the efficient treatment of higher airflow rates. The Vapor Box adsorbers are constructed of mild steel and have two part epoxy coatings on the inside and outside to provide long service life. The boxes are equipped with 24 inch manholes for easy access during carbon change-outs.  A drain allows for the removal of condensation from the vessel.  Standard carbon is GC 4x8S Coconut Shell but other sizes and grades are available for special applications.  Please call General Carbon if you have any questions about your application.

                                                              1 Dimensions and/or specifications can change without notice.

                                                              2 Maximum CFM rate is at 60 fpm superficial velocity.

                                                              3 Weight is standard carbon.  More or less weight of other carbons may be fit in vessel.

Installation & Start UP - Vapor Box series adsorbers require no special procedure for start up. Remove the shipping plugs from the inlet and outlet and make the proper connections to your system. The unit is now ready for service and can be started up. Unions or quick connect fittings are recommended if the unit will be disconnected frequently. Multiple units are usually connected in series with testing advised between the units to determine when the first unit needs to be changed out.

Maintenance - When in use, the only maintenance the Vapor Box Adsorbers require is testing for contaminants in the influent and effluent streams, and checking the operating pressure of the system. Monitoring the contaminant concentration level into the last unit in a series arrangement is the recommended safeguard against having breakthrough in the final outflow. When the concentration of contaminants in the flow coming out of the lead unit equals the concentration of the flow into the unit, the unit has reached its removal capacity and should be removed from service. The working life of each adsorber is dependent upon the type of contaminant in the air as well as its concentration and the airflow rate. A pressure relief device is advised to prevent damage to the adsorber in the event of excessive pressure buildup.

Recharging - Once the carbon is saturated by contaminants, the unit should be taken off line. If connected in series mode, the next down stream unit should be moved into the lead position and a fresh unit put at the end of the train. All shipping plugs must be replaced when the unit is to be transported. To purchase replacement carbon or to arrange for carbon changeout, please contact our office.

Disposal - Dispose of the spent carbon in accordance with Federal, State and local regulations.

Caution!
Wet activated carbon removes oxygen from air causing a severe hazard to workers inside carbon vessels. Confined space/low oxygen procedures should be put in place before any entry is made. Such procedures should comply with all applicable local, state and federal guidelines.
