TDA-4Blite 空气悬浮粒子发生器描述
ATI制作便携式的Laskin Nozzle产尘型悬浮粒子发生器能产生次微米的多种直径的油雾悬浮粒子，当系统中的流量在50 到 8,100 立方英尺每分钟之间（压力在20 psig下）时，浓度范围为10 到100 微克/升。
TDA-4Blite 空气悬浮粒子发生器和气溶胶光度计被用于高效的空气过滤系统中完整性测试或查找泄露源测试。过滤器制造商用这个设备去扫描ULPA和HELP（超高效，高效）过滤器去验证它们的产品。过滤器论证商用这个设备去确认过滤器有没有在运输中损坏和是否*正确的被安装并没有任何泄露。
在合适的悬浮粒子发生器和光度计的结合下，过滤器的一些不足，象针孔，薄点，垫圈泄露，结构泄露或密封问题都能迅速并且定量的测到加以修正从而保护产品和人员。
TDA-4B和TDA-4Blite 空气悬浮粒子发生器功能在几个方面得到了改进，象坚固的不锈钢结构，大的填装口，独立的喷头控制和3英寸标准的卫生接头输出。一个可选的软管适配器，零件号为9300100，为导入悬浮粒子进入正压系统而提供。
TDA-4Blite 空气悬浮粒子发生器功能
TDA-4Blite 空气悬浮粒子发生器是一个更小的，低容量版本的TDA-4B，但仍旧保持所有的*功能。
TDA-4B TDA-4Blite 空气悬浮粒子发生器lite被设计用于生物安全柜。它的小尺寸和低成本使它成为理想的用于生物安全柜测试和HEAP 过滤器的真空测试。

ATI悬浮粒子发生器 / TDA-4B产尘仪 / 空气粒子发生器 / PAO油发生器Description
ATI manufactures portable Laskin nozzle aerosol generators which produce a sub-micron polydispersed oil mist aerosol in concentrations from 10 to 100 micrograms per liter （ug/l） at air flows from 50 to 8,100 cfm @ 20 psig.
Aerosol generators and photometers are used to integrity test or locate leaks in high efficiency air filtration systems. Filter manufacturers use this equipment to scan ULPA and HEPA filters to verify they are free from manufacturing defects. Filter certifiers use this equipment to insure that filters were not damaged in shipping and have been installed properly, eliminating any leakage.
With the proper generator and photometer combination, filter deficiencies such as pinholes, thin spots, gasket leaks, frame leaks or seal problems can be quickly and quantifiably pinpointed and corrected thus protecting product and personnel.
Both the TDA-4B and the TDA-4B Lite feature several improvements including rugged stainless steel construction, large fill port, individual nozzle control, and a 3" standard sanitary fitting outlet. An optional hose adapter, part # 9300100, is available for introducing the aerosol into positive pressure systems.
TDA-4B Lite Features
The TDA-4B Lite is a smaller, lower capacity version of the TDA-4B that still retains all the improved features. The TDA-4B lite was specifically designed for use in biosafety cabinets. Its small size and low cost make it the ideal generator for biosafety cabinet testing and HEPA filter vacuums.
The TDA-4B Lite has 3 Laskin nozzles. When its total output at 20 psig is diluted by 405 cfm of air, the aerosol concentration is approximay 100 ug/l. Two valves permit the unit to operate with 1 to 3 nozzles to provide a wide range of aerosol concentrations.
