UV Diffusers Explained

Air velocity in ventilation ducts and air handling units is very high, which makes it challenging to achieve proper UVC air sterilization

Virus particles passing through ducts at high speed are not in contact long enough with UV-C rays to be properly irradiated, the exposure time is too low

With UV Diffusers, UV-C irradiation happens at the very end of the duct line, where the air velocity is at its lowest

Then we pressurize the air inside the plenum

Decreasing the air velocity even more

Virus particles are now passing through UV-C light at low speed

Comparing Air Velocity in Duct vs UV Plenum

Increasing virus and bacteria exposure to UV-C light – and irradiation efficiency – by a factor of 2 to 8 times

The air first passes through the irradiation chamber which has a built-in UV-C lamp. The configuration of the chamber, the angles and materials reflecting the light, as well as the airflow passing through the chamber: everything has been designed to boost UV-C irradiation inside the chamber.

UV-C Air Disinfection

Once the air is sterilized and pathogens are neutralized, the air then passes through a MERV-9 filter to catch larger particles like dust, mold spores and allergens, and even some of the microbes who may not have been deactivated by the UV-C light.

UV Diffusers use air filtration to clean the air

The last yet very important step is to distribute the purified air in the room as efficiently as possible

UV Diffusers Distribute the Air With a High Discharge Velocity

All UV diffusers distribute the air with a high discharge velocity, ensuring proper mixing of room air even at lower air volumes. This is important in order to remove as much contaminated air as possible and maintain low levels of microbial concentration in the room.
