Monitoring
The 4B/4B-Lite provides
  • Airflow rates from 685 – 14.000 m3/hr for a wide range of testing requirements
  • Flex-fuel capabilities, allows for the use of different reagents
  • Rugged Portability
  • Safe and reliable Operation
  • Lightweight and rugged, ideal for remote locations
A Flexible Solution
The 4B family of aerosol generators produce an industry standard true Laskin III-A repeatable aerosol and feature adjustable aerosol concentration output to meet multiple application requirements. These generators are 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. 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 700 till 14,000 m3/hr.
Rugged Convenient Design
The 4B family features rugged stainless steel, with easily cleanable construction, a large fill port, jet and pressure control, and a standard three-inch sanitary fitting outlet collar.
Optional Accessories
  • Hose Adapter Kit: (hose not included), used to introduce aerosol remotely, connects easily to the standard outlet collar.
  • Heavy Duty Case: Heavy duty, water-proof transport case with wheels. Accommodates either a 4B, 4B-Lite or 6D generator, with space for the optional hose adapter.
