ABSTRACT:
Apparatus is provided for use in filling charcoal adsorber air filter cells by dispersing the particulate charcoal into the filter while the apparatus is disposed vertically above the filter. The apparatus is particularly adapted to produce an even packing density of particulate charcoal in the filled air filter without the necessity of vibrating the air filter once the charcoal has been allowed to fill the filter to the top. A method is provided for semi-automatically, pneumatically filling the apparatus and the charcoal adsorber air filter. Some embodiments of the apparatus are adapted for filling two or more charcoal adsorber air filters simultaneously.
