Thermal Aerosol Generator Model 3990-02 – High-Capacity Vapor Aerosol Generator for HEPA Filter Testing

The Thermal Aerosol Generator Model 3990-02 is a high-capacity, thermal-type aerosol generator engineered for HEPA and ULPA filter integrity testing, cleanroom validation, and airflow contamination analysis. Designed for demanding cleanroom applications, this unit rapidly vaporizes PAO or DOP aerosol reagents in under two minutes using a powerful inner heating element.

With a flow range of 500–70,000 cfm, it supports extensive system testing, including large-scale HVAC and pharmaceutical environments. Its stainless-steel pressure-resistant design, 2.4-inch real-time LED screen, and intuitive metering valve make it a versatile and operator-friendly solution for both portable and fixed installations.

Whether for nuclear facilities, biosafety cabinets, or controlled environments, this vapor aerosol generator offers precise aerosol delivery under inert gas flow.

Key Features

  • Thermal vapor generation with ultra-fast 2-minute warm-up

  • 2.4-inch LED screen displays real-time heating zone temperature and inner gas pressure

  • Adjustable aerosol concentration up to 100 μg/L

  • Supports large flow rates from 500 to 70,000 cfm

  • Oil capacity of 1.8L for up to 70 minutes of continuous operation

  • Instant heating system with safe shut-off and pressure relief mechanisms

  • Built-in metering valve for precise aerosol output control

  • Stainless steel housing with shoulder and carry straps for portability

  • Operates on inert gas (N₂, CO₂); not compatible with compressed air

  • Complies with ANSI/ASME N509/510 particle distribution standards

What is the Model 3990-02 used for?

It’s used for generating high-concentration thermal aerosol vapor for HEPA/ULPA filter testing, HVAC validation, and controlled environment compliance.

How quickly can it generate aerosol?

The heating time is less than 2 minutes, making it extremely efficient for fast deployment.

Can I use compressed air as the gas source?

No. Only inert gases like nitrogen or carbon dioxide should be used to avoid fire or explosion risks.

How long does the unit operate continuously?

It can run for up to 70 minutes on a full 1.8L tank of reagent, depending on flow rate and metering.

What is the required input pressure?

The generator requires a steady 345 KPa (50 PSI) inert gas input pressure for stable aerosol production.

What types of aerosol reagents are supported?

It supports industry-standard reagents like PAO, DOP/DEHP, DOS/DESH, Ondina EL, and mineral oil.
