ABSTRACT:
A portable cleanroom cabinet (20) having a portable cabinet device (22), configured for mobile transport, which provides a cavity (23) formed for receipt of at least one electronic component (21) therein. The cabinet device (22) defines at least one air flow passage (32) having a first opening (33) in flow communication with an upstream end (29) of the cavity (23), and a second opening (35) in flow communication with an opposite downstream end (36) of the cavity (23). Collectively, these passages and cavities define a recirculating airflow pathway such that substantially all the air flowing through the cavity (23) from the upstream end (29) to the downstream end (36) thereof recirculates back through the air flow passage (32) to the upstream end (29). A blower assembly (30) is provided communicably coupled to the recirculating airflow pathway to drive the recirculating air flow, and a filter element (31) positioned in the recirculating airflow path such that the recirculating air flows through the filter element (31) prior to entering the cavity (23). The flow of recirculating air through the cavity (23) from the upstream end (29) to the downstream end (36) is substantially evenly distributed across a transverse cross-sectional dimension thereof.
