UV Diffusers Explained

Air velocity in ventilation ducts and air handling units is often too high to achieve proper UVC air sterilization

Virus particles passing through ducts at high speed are not in contact long enough with UVC rays to be irradiated

With UV Diffusers, we use UVC irradiation at the 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 UVC light at low speed

Comparing Air Velocity in Duct vs UV Plenum

Increasing virus exposure to UVC light – and irradiation efficiency – by a factor of 2 to 8 times

The air passes through one or two UVC lamps, also positioned for optimal UVC exposure and air disinfection performance

Once the air is sterilized and pathogens are neutralized, the air then passes through a MERV-9 filter to catch larger particles like dust and pollen

Last but not least, we ventilate the room with the newly purified air

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.
