UV Diffusers Explained
Air velocity in ventilation ducts and air handling units is very high, which makes it challenging to achieve proper UV-C irradiation and air disinfection
Virus particles passing through ducts at high speed are not exposed long enough to UV-C rays to be properly neutralized, 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
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.
Once most microbes are deactivated, the air then passes through a MERV-9A filter to catch larger particles like dust, mold spores and other allergens.
The last yet very important step is to distribute the purified air in the room as efficiently as possible
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.
Adjustable and high induction swirl diffusers, for airflows between 50 cfm and 550 cfm, there’s a perfect UV Diffuser for every commercial application
