The Carbon Control Canister System (GAC) vapor phase
canisters are designed for a economical cost effective
approach to air or vapor treatment for short or long term
emission applications. We offer carbon steel and 100%
stainless steel canisters. Systems contain all of the
necessary requirements for use as an effective granular
carbon system for air or vapor phase process treatment
applications.

All GAC Systems include a level and secure carbon bed
support across the entire canister lower sectional area
which creates a plenum region below the support area
for proper inlet distribution across the GAC system. The
GAC canisters are constructed of unlined carbon steel or
T304 stainless steel, both systems offer a stainless steel
perforated screen and angle bed support for use with
activated carbon during air treatment.

The GAC vapor phase carbon adsorber canisters are for
treatment up from 10 to 2000 cfm.

The vapor phase adsorbers are provided with a wide
variety of vapor phase activated carbon products that
can be specific for your air or vapor treatment application.

Features
GAC vapor phase carbon adsorption canisters offer
many important construction features that make the
system an effective value driven option for many
industrial applications:

  • Sturdy Carbon or Stainless Steel Construction.
  • Operating Pressure Range up to 3 psig.
  • No painting necessary and maintenance free
    corrosion resistant materials.
  • 33" Diameter Access Port for easy activated
    carbon installation and removal.
  • Sturdy, Permanent Stainless Steel Bed Support
    across the full canister base sectional area. With
    Stainless Steel 1/16" perforated orifices for even
    vapor distribution across the entire bed for
    maximum inlet volumes and very low pressure drop.
  • 4" Carbon or Stainless Steel Threaded Pipe Nipple
    for process connection.
  • 4" Carbon or Stainless Steel Exhaust Vent Outlet.  
  • Stainless Steel Grounding tube for protection
    against explosion.
  • Stainless Steel Removal Hooks for loading and
    unloading.

Installation
The GAC Canisters are shipped ready for installation
with the activated carbon pre-installed. The GAC system
is fully self supportive and it is preferred to set on a level
accessible area for even vapor introduction. The GAC
system should be as close to the emission source as
possible. The GAC system requires only a flexible
connection and a pipe nipple for easy hookup. The 4"
connection at top may be used for a flexible connection
to remove exhaust away from the area or if preferred left
open to exhaust emissions.

The GAC systems may be directly connected to storage
tanks and other process containers. Air force through
the system may be made by using a positive forced draft
fan or blower or use the pressure within the process tank
or vessel, if the required pressure is sufficient to
overcome the systems pressure drop.

A safety relief valve should be provided on the storage
tank or process vessel for protection against any
blockage or system plugging. A back flow preventer
should be installed between the process vessel and the
GAC system to prevent possible back flow. Should
elevated concentrations of VOC be above 1% by volume
a heat sink in the form of sprayer may be used or simply
add dilution air on the inlet process side.

When controlling organic compounds it is recommended
that the humidity be maintained below 50%. Higher levels
of humidity will fill the carbon pores and reduce the
carbon's ability to adsorb the emissions.
After the treated emissions exceeds the GAC systems containment concentration level or what is termed the
systems breakthrough point, the GAC system's granular carbon should be replaced. Either exchange the
complete GAC system or should replacement on site be preferred isolate the inlet valve and remove the canister's
33" top to begin the vacuum operation. New granular carbon may be placed in the GAC system through the 33"
GAC canister top and refill to the recommended level. American Environmental Fabrication & Supply can provide
a full service solution to include removal, refill operations and waste management of the spent carbon. Call for
more information about our services.
