ATI 4B – 8100 CFM


The 4B series family of Laskin-Nozzle aerosol generators are durable, portable, and reliable.

Designed for testing filter systems ranging from small glove boxes to large cleanroom plenums, ATI Laskin Nozzle generators provide the ideal solution for creating a polydispersed, submicron aerosol to certify and qualify in-situ filter systems.

Aerosol concentration output varies by generator model; however, concentrations can be achieved from 100 μg/l down to 10 μg/l at airflows ranging from 405 to 8,100 CFM.

It is ideal for testing a wide variety of filter systems with air flows up to 2,000 CFM by generating a poly-dispersed, sub-micron aerosol.

Applications include workstations, negative- pressure filtration units, biological safety cabinets, ceiling modules and more. It can also be used for testing positive pressure systems using an optional Positive Injection Pump and hose adapter kits.
