5D Thermal Aerosol Generator

The 5D Thermal Aerosol Generator is designed for operators who require a wide range of aerosol output concentrations to perform leak tests on smaller clean air cabinets through cleanroom air handling systems.


  • Nuclear facilities
  • Pharmaceutical manufacturers
  • Medical facilities and cleanrooms
  • Independent filter certifiers

Key Features & Benefits:

  • High aerosol output
  • Widest range of system flow rates
  • One minute warm-up time
  • Flex-fuel capability
  • Rugged portability
  • Safe and reliable operation


Save time and money in the most demanding multi-filter cleanroom installations. In high-volume HEPA and ULPA air flow environments, the 5D can significantly reduce the time it takes to conduct filter leak test scans, generating aerosol concentrations that can challenge the largest Air Handling Unit (AHU) configurations. With 1- to 2-minute warmup and cool-down times, begin testing high-flow systems without waiting, and be ready to store and move the unit minutes after the job is complete.

Rugged Portability

The 5D components are housed in a stainless-steel enclosure designed to withstand the rigors of portable filtration-system certification. Its lightweight, slim profile and supplied hand and shoulder straps make it an everyday, portable aerosol generator.

Heavy-Duty Case with polyurethane      wheels and a retractable handle allows              for easy transport.


Generating the widest aerosol concentration range available, the 5D accommodates both high- and low-flow environments, from cabinets1 to the most demanding cleanroom installations. And with flex-fuel capability, the 5D can use the following reagents, including DOP (DEHP), PAO-4, DOS (DEHS), Ondina, or mineral oil.2

Safe and Reliable

An innovative design minimizing system thermal requirements provides a faster, simpler, and safer alternative to other available solutions. The 5D is certified to comply with all applicable electrical and safety requirements, including CE and RoHS 2 standards.

1. Per NSF/ANSI 49, use 4B/4BL/6D laskin nozzle generators for biosafety cabinet testing.
2. Parrafin Oil and Corn Oil should not be used with a thermal generator.
