HARDWALL RECIRCULATING DESIGN
Available from Hutchins & Hutchins
The Legend Hardwall Recirculating Design Cleanrooms are ideal when temperature or humidity control is required. The conditioned air inside the plenum space is drawn into the SAM Fan Filter Units and the filtered air then passes into the cleanroom. The air from the cleanroom is forced into the return air grilles located in the lower wall sections and is recirculated up the return air chases within the walls to the plenum. The air is mixed with make-up air inside the plenum and drawn thru the SAM units again.
