Abstract
A flowhood work station has an inspection chamber having a perforated inspection surface. An air filtration housing is in fluid communication with the perforated inspection surface. A blower is capable of directing air downwardly through the perforated inspection surface. A return air plenum is in fluid communication with the perforated inspection surface and with the air filtration housing. The return air plenum captures a substantial portion of the air passing through the perforated inspection surface and directs the air to the air filtration housing.
