How many boxes of HBOS-Carb will I need to order refill my vapor adsorbers ?
There are many types of vapor adsorbers currently used in the industry. The image to the left is one of an older style "coffin" type adsorber that utilize a "bottom-up" air flow design.
Changing out the pellets in these systems involve removing many bolts along the top, cleaning out the old pellets, cleaning and/or replacing the screen material at the bottom of the unit, and then putting the new carbon into the unit. It is also critical to be sure the gasket material is still adequate to properly seal the unit after the top is repositioned and the fasteners are reapplied prior to starting up the unit.

Fiberglass Square or Rectangular Tanks
How much carbon needed is usually based on how many CFM the unit is designed to deliver, and fiberglass units take more pellets than stainless steel units of same CFM size. With that in mind, the following table applies to most fiberglass vapor adsorbers in use, regardless of manufacturer:
Fiberglass Units How many boxes
Unit CFM of HBOS-Carb
200 13 boxes
500 26 boxes
1000 50 boxes
2000 76 boxes
4000 151 boxes
Fiberglass Units How many boxes
Unit CFM of HBOS-Carb
200 13 boxes
500 26 boxes
1000 50 boxes
2000 76 boxes
4000 151 boxes
Stainless Steel or Aluminum Round or Oval Tanks
Stainless Steel units are typically not square shaped like the first generation fiberglass vapor adsorbers, so they generally take less carbon than the same size stainless steel unit. They are also available in more sizes. Here are typical pellet needs for stainless steel vapor adsorbers:
