Abstract
A closure apparatus is provided for optionally closing and opening a storage hopper portion of an adsorber filter fill system used for filling adsorber filter cells in a gas adsorber filter system. The closure apparatus is particularly adapted to have a portion thereof move with respect to a metering means of storage hopper of an adsorber filter fill system between first or open and second or closed positions, so as to optionally, selectably permit the opening and closing of the storage hopper. The closure apparatus provides a substantially air-tight seal at holes in the metering means of the adsorber filter fill system when the closure apparatus is at the closed position. The closure apparatus is designed so that its sliding operation and maintenance of substantially air-tight seals is not adversely affected by the presence of any granules of adsorbent which remain in the holes in the metering means or in the vicinity of the holes in the metering means once filling of the adsorber filter system is completed.
