A Tough, Portable Solution

The 4B Laskin-Nozzle aerosol generator is 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. End users include independent filter certifiers, government and commercial nuclear facilities, pharmaceutical manufacturers, medical facilities, and other industrial applications.

A Flexible Solution

The 4B generator produces an industry standard true Laskin III-A repeatable aerosol and features adjustable aerosol concentration output to meet multiple application requirements. The 4B generator is used in conjunction with an aerosol photometer to measure the aerosol penetration of an individual filter or filter system, typically to identify, quantify, and repair leaks. Concentrations can be achieved from 100 μg/l down to 10 μg/l at airflows ranging from 810 to 8,100 cfm*.

Rugged Convenient Design

The 4B features rugged stainless steel, with easily cleanable construction, a large fill port, jet and pressure control, integrated pressure relief valve, and a standard three-inch sanitary fitting outlet collar.

Integrated Pressure Relief Valve

An integrated passive pressure relief valve provides added operator safety.
The pressure relief valve prevents pressure build-up in the tank if the aerosol outlet port is accidentally blocked.

Optional Hose Adapter Kit

An optional hose adapter kit (hose not included), used to introduce aerosol remotely, connects easily to the standard outlet collar.

Optional Heavy Duty Case

Heavy duty, water-proof transport case with wheels. Accommodates either a 4B or 6D generator, with space for the optional hose adapter with cap to prevent spills. (Universal case with 6D generator shown).
