| 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. |
