Vacuum Pump Charcoal Trapping Exhaust Filters

Removes Contaminants From

Vacuum Pump Exhausts

K

oby Air Purifiers are installed on exhaust ports of roughing pumps to adsorb

remaining compressed air contaminants such as oil aerosols, oil vapors, certain

other hydrocarbon vapors, and trace moisture. They also trap all foreign solid

particles such as dirt, dust, rust, and pipe scale down to 0.5 microns in size. In addition,

Koby Air Purifiers can be used for efficient adsorption and removal of organic vapors and

aerosols, noxious odors, certain foreign gases and bacteria, and are effective in removing

certain inorganic vapors and aerosols from compressed air and vacuum air.

These carbon filters can be used in conjunction with oil mist eliminators. The oil mist

eliminator traps and returns the oil to the vacuum pump while the Koby Air Purifier removes

any remaining contamination which might otherwise be emitted into the laboratory air.

Range of Possible Adsorption Capacities

Adsorption Capacity

The carbon used in the manufacture of

Koby Air Purifiers has a huge internal and

external surface area with an affinity for

adsorbing organic contaminants. Each

gram of carbon has a surface area of

approximately 1500 sq. meters, making

Koby Air Purifiers particularly efficient for

most air purification and gas phase appli-

cations.

Actual adsorption capacity can be

as high as 80% of carbon weight depend-

ing on the specific compound being

removed. Generally (but not always),

adsorption capacity of activated carbon

increases with molecular weight, boiling

point, and concentration of contaminants.

Compounds with low molecular weights

and/or

highly polar compounds will not be

sufficiently adsorbed at low concentrations.
