TRACS® Model TM500 Ceiling Mount UVC Air Purification

Ultraviolet Germicidal Irradiation (UVGI) employing UVC light has been used as a means of destroying airborne bacteria and disease for years. Airborne microorganisms have been shown to be destroyed when subjected to certain levels of UVC light at certain wavelengths (254nm).

Viruses may be small enough to slip by a HEPA filter, but most viruses are very susceptible to the effects of UV light. The UV lamps in the TRACS Manufacturing ceiling product line also radiate on the HEPA filter, where the dust, bacteria, and microorganisms are collected.

In HEPA-only systems, mold and microbial growth can occur on the HEPA filter, so HEPA filters must be replaced at least once per year (even if the HEPA filter is not clogged). If they are not replaced, the microorganisms can actually eat through the HEPA media (this is known as bacteria grow-through), and be dispersed throughout the room.

However, in the TM ceiling product line, given the HEPA filter is constantly bathed in UV light, mold and microbial growth cannot occur. As such, the HEPA filters in our systems can last up to three years (depending on particulate load), thereby lowering unit maintenance costs.

We patented the distance between the HEPA filter and UV-light and by having the UV shining on the “dirty” filter, all trapped microorganisms are deactivated, making it safer for the maintenance personnel to change and handle the spent filter.

In summary, UVGI is an effective and valuable secondary or backup technology for high risk infection control applications. Imagine what it could do for your gym, office, or home.
