- Remove a wide range of chemicals from airstream to allow
ductless exhaust fume purification
- Bonded-charcoal design minimizes voids, improves efficiency, reduces particle sloughing
- Improves conditions for technicians working with chemicals or applications that create fumes
- Custom sizes available—call Terra with your specifications
These carbon filters, manufactured
from coconut-shell based activated charcoal of 8-12
mesh size, are used to remove a broad range of organic
compounds and solvent fumes. Special processing ensures
a large surface area per gram weight. They function
through physical adsorption of molecules in the pores
of the activated charcoal by van der Waals forces.
Carbon filters are designed for use in the Terra
systems listed in the ordering table below (other sizes
can be custom ordered). Typically, each Terra ductless exhaust
system includes a filter housing that holds the desired
purification filter along with any prefilter or postfilter
required. For optimal filter effectiveness, Terra recommends
use of a prefilter to extend the time that the exhaust fume
is exposed to the filter medium. In particle-sensitive environments,
a HEPA or ULPA filter may be added.
Note: Terra recommends thorough testing of filter performance
in each application prior to exhaust release, and assumes
no responsibility for damage or injury that may result as
a consequence of improper filter selection or use.

Chemical Filtration Table for Activated Charcoal (AC)
The
table below indicates the filter recommended for use with a
wide range of chemicals commonly found in laboratory and manufacturing
environments. For each chemical, it also provides an estimate
of filter capacity.
Unless otherwise specified, filter efficiency with the chemical
indicated approaches 100%. An asterisk (*) indicates poor
adsorption by any filter; use of the specified filter is not
recommended with these chemicals except where they occur in
low concentrations, and frequent exhaust testing is advised.
Filter capacity is given as the equilibrium saturation capacity,
a standard test procedure for activated carbon (ASTM-D3467).
The capacity is expressed as the final filter weight at saturation
as a percentage of initial filter weight. The actual capacity
obtained will depend on the conditions of use (concentration
of contaminant feed, temperature, humidity, etc.).
Note: All data below represent
typical, not guaranteed, test results. Terra recommends thorough
testing of filter performance in each application prior to
exhaust release, and assumes no responsibility for damage
or injury that may result as a consequence of improper filter
selection or use.
