Abstract

A system for minimizing free airborne particles generated by movement of a two component powder material 16 within a partially open container 15. The two component material 16 includes a relatively large component of about 50- in size and a relatively small component is less than about 4O,-in size as is used in carrier and toner for developing electrostato-graphic images on drum 12. A tubular filter 32 with predeter-mined pore size is positioned across the flow of the two component material and connected to a source of negative pressure.

A system for minimizing free airborne particles generated by
movement of a two component powder material 16 within a
partially open container 15. The two component material 16
includes a relatively large component of about 50~ in size and
a relatively small component is less than about 4O,~in size as
is used in carrier and toner for developing electrostato-
graphic images on drum 12. A tubular filter 32 with predeter-
mined pore size is positioned across the flow of the two
component material and connected to a source of negative
pressure.
