Upper-Room Ultraviolet Germicidal (UVGI) Air Disinfection (With Photocatalyst Technology)

Model: AHUA-1000

With innovative internal mirror reflection and lens design and fully imported UV-C lamps for maximum UV-C energy output, Alphatch AHUA-1000  is effective to interrupt the transmission of airborne infectious diseases.

The upper-space Germicidal UV Sterilizer can realize the REAL upper-region air disinfection. The lower part of the room is kept relatively UV-C free, minimizing exposure to persons in the lower part of the room. Inactivation in this context means the loss of the ability to replicate and form colonies. Meantime, with larger coverage and lower cost.

Recommended Disinfection Area: 30㎡

The ultraviolet upper Irradiation air sterilizer realizes the true upper-layer flat-beam of ultraviolet light irradiation by internal mirror reflection and optical control with the original imported UV lamp. Through the use of the natural convection effect of indoor air with the machine air circulation system turned off, the infectious bacteria such as pulmonary tuberculosis bacteria floating and dispersed in the air will be quickly killed when they rise to the ultraviolet radiation area. Upper-room UV air disinfection There’s a built-in fan within the AHUA-1000 upper-room UVGI purifier. When the fan is turned on, air will be drawn into the UVGI purifier for purification and disinfection, then the treated air will be supplied to the room (Forced convection for air purification and recycling disinfection). The room air is constantly mixing (Nature convection) even without the assistance of HVAC ventilation or fans.  Complete microbial inactivation occurs through the cumulative effect of exposure over time as infectious particles are carried repeatedly to the upper room. Each pass inactivates the infectious particles until their concentration in the lower part of the room is effectively diluted. Having said that, a mixing fan, it will increase the effectiveness of the UVGI system heavily. The more reasonable air convection, the higher performance. Kindly note, when in an infectious ward,  forced recycling air is forbidden, the fan needs to be turned off.

What Makes the Upper-room Germicidal UV-C Systems for Air Disinfection Stands Out?

What makes Alphatch Upper-Room Ultraviolet Germicidal Air Disinfection different from a Conventional Upper-room germicidal UV-C system is that the conventional UVGI fixture ONLY adopts upper-space UV radiation sterilization. AHUA -1000 with higher and better sterilization performance.

1) TiO2 coating filtration system + Upper-space UV radiation sterilization + UV photocatalyst sterilization + Ionization air cleaning technology
2) High/Medium/Low forced air recycling, sterilization and purification, and Silent Nature Sterilization and purification
3) Time-setting function for auto disinfection. Can be used at the beginning and the end of the day, during occupied or for continuous 24-hour operation.
4) Infrared detection and UV auto-closing protection when reaching 2.1m height. Can keep working when the room is being occupied.
5) Start and stop timing settings and multi-modes available.
