美国Glas-col气溶胶发生器/吸入暴露系统

An anodized aluminum tank, 22-3/4″ in diameter by 22″ deep, with a volume of 5 cu. ft., constitutes the infection chamber.

此感染箱由阳J氧化铝箱体构成，直径22.75’’，深22″，体积5立方英尺。

A stainless steel, wire mesh basket, 22″ in diameter by 14″ deep, is provided. The opening in the basket lid can be rotated to each of 5 equal compartments. Each compartment can hold 20 mice, 3-4 guinea pigs, or one rabbit; for a total of 100 mice, 15-20 guinea pigs, or 5 rabbits.

配有不锈钢分隔篮，直径22″，高14″。分隔篮分成5个相同大小的分隔间，每个分隔间的盖可以分别打开，每个分隔间能装20只小鼠、3-4只豚鼠或者1只兔子；因此总共可装100只小鼠、15-20只豚鼠或者5只兔子。

A clear acrylic lid, impervious to ultraviolet rays, supports the UV lamps and sample port. Four latches provide pressure on the tank gasket to seal the lid to the chamber.

一个透明的聚丙烯酸酯盖，不透紫外线；配有紫外灯和样品口。四个保险栓锁上后可使盖子密封。

The apparatus is housed in a sturdy stainless steel cabinet, mounted on casters. Flowmeters, controls, and nebulizer are mounted on a recessed panel. Cabinet size is 30″ wide by 33″ deep by 33″ high. Weight is about 170 pounds. The incinerator is at the right rear corner of the cabinet. Depending on position, it adds 11″ to either the depth or the width. A minimum space of 6″ is recommended between the incinerator and adjacent walls or other equipment.

所有器件都装在一个坚固的、箱底带有脚轮的不锈钢箱体内。流量计、控制器和雾化器都固定在箱内的面板上。箱体的宽为30’’，高为33’’，长为33’’。重约170磅。焚烧装置固定在箱体外面的右后侧，所以使装置整体宽度和高度各增加了11″。建议吸入暴露系统放置时与墙面或者其它仪器间距至少6″。

The exhausted air passes through an HEPA filter unit with a glass fiber medium that has a minimum efficiency of 99.97% on particles as small as .3 micron. Filters are individually DOP tested at a flow rate of 100 CFM at 1.2″w.g.

废气通过一个带有玻璃纤维过滤介质的高效过滤器（HEPA），其对小到0.3微米的颗粒的zui小过滤效率也能达到99.97％ 以上。在流速为100 CFM和压力为1.2″w.g.的条件下，过滤器经过了独立的DOP测试。

Allen Bradley programmable control regulates the four cycles of the Inhalation Exposure System (preheat, nebulizing, cloud decay, decontamination) and increases its efficiency. Displays time in seconds.

Allen Bradley 程序控制器能控制吸入暴露系统的四个循环过程（预热、雾化、除雾和消毒），并且能提高效率。显示时间为秒级。

Two durable and easy-to-read flowmeters accurately measure the airflow to the chamber. The compressed air line flowmeter has a range of 2 to 20 SCFM, and the main air flowmeter has a range of 10 to 100 SCFM.

两个耐用且易读的流量计能较精确测量通过箱体的空气流量。压缩空气流量计的测量范围为2-20 SCFM，主要空气流流量计的测量范围为10-100 SCFM。

An all-glass nebulizer-venturi unit with septum is provided for atomizing the suspension under pressure and combining it with the air drawn in from the room to provide the proper mixture to be delivered to the chamber.

配有带塞全玻璃制雾化器，加压使悬浮物雾化，然后与过滤的主空气流混合。

The system features a very quiet and reliable vacuum pump to provide adjustable flows through the tank of up to 1.67 CFM.

吸入暴露系统装有噪声小且质量可靠的真空泵，使通过箱体的空气流量可调，其zui高可达1.67 CFM。

The system is supplied with an air incinerator on the outlet.
吸入暴露系统的出气口处安装有一个空气焚烧装置。
