The Dust Deputy 2.5 Deluxe Cyclone Separator Kit from Oneida Air Systems Inc.  stops clogged wet/dry vac filters & eliminates suction loss. It features up to 2x the airflow of smaller cyclones, with a transparent, collapse-proof 5 gal. bucket that allows dust fill level to be easily observed from across a shop. It stops up to 99.9% of fine dusts and bulk debris from clogging a  vacuum’s filter — eliminating suction loss while saving time and money on expensive replacements, Oneida says.
