Safety enclosure reaches Class 10
Airo Clean Engineering Inc.`s Airo/Neg Safety Enclosure, which is used in pharmaceutical applications, universities, hospitals, contract testing labs and government research facilities, provides protection for researchers. The system provides either positive or negative pressure, and it reaches a Class 100 environment when in positive mode and Class 1,000 when in negative mode. The only manual controls are the on/off rocker switch and the pressure control knobs. An airflow meter and pressure gauge displays current flow modes, and a red pilot light indicates the need for prefilter replacement. The enclosure has 2-in. thick panels with fully gasketed wall-joints, a hinged front support bar at the floor. It measures 79 in. L by 37.5 in. W (outer dimensions), with inner dimensions of 74 in. L by 35 in. D by 72 in. H. The air flow rate is 25 cfm per sq. ft. with a unidirectional downward flow. The blower section is all-steel, welded construction, with a baked enamel finish both inside and out. The HEPA filter minimum efficiency is 99.97 percent DOP, UL Class 1. The system can be shipped in two pieces or dismantled for a quick assembly in only 20 minutes.
