RIGEL RI8401 Aerosol Generator

-for HEPA filter integrity testing

Aerosol Generator Produced by Condensation of Oil Thermally Vaporized

Rigel RI8401 Thermal Aerosol Generator is the perfect choice to test and validate all kinds of areas. This is the smallest and lightest aerosol generator on the market.

Plus, having a easy-drainable tank due to a valve located at the bottom makes this unit the most practical unit you can work with. The RI8401 has the ability to start the generation with a remote control (optional).

The RI8401 has a great autonomy in continuous duty: at a median concentration it can generate up to 8 hours.

No need for special kind of oil to work with this unit: it generates perfectly with the most common fluid such Emery, Ondina, PAO4 and DEHS.

This unit starts to generate a consistent amount of aerosol at very low pressures (5 PSI/0.35 bar), giving the possibility to work even in very small areas.

RIGEL RI8401 gives its best in cleanrooms , operating rooms, safety cabinets, isolators and rabs.
