CARBON FILTER EFFICIENCIES
Typical filter efficiencies are >99% and this efficiency is maintained for most of
the filter life.
Filters should be changed when efficiency has reduced to below 90%.
ABSORPTION CAPACITIES
Monmouth Circulaire cabinets are fitted with very large capacity filters, with a
typical value of >30% for hydrocarbons.
The cabinet main filter has the following nominal absorption capacities:
Model
Carbon Weight
Hydrocarbon capacity
at 30% absorption
Circulaire C550
1 X 12Kg
3.6kg
Circulaire C650
1 X 14Kg
4.2kg
Circulaire C900
1 X 16Kg
4.9kg
The given weight is approximate to standard activated carbon.
Impregnated carbons have higher densities and will increase filter weight.
Contact Monmouth Scientific for absorption capacities for different
applications.
