U33 Single Side UVC Upper Air Purification System

This device disinfects the upper air level above 2.1m with UVC radiation without affecting human activities below.  Automatically shuts off when human presence is detected within the purification layer.  Internal 3-speed fan circulates surrounding air through the UVC disinfecting zone, resulting in a 99.9% efficiency.

Product Features

Working Principle

There is a special high-energy UVC lamp tube energy-concentrating layer device contained within the equipment, which is installed on the ceiling and forms a radiation layer in the upper section of the room.  The centrifugal fan quickly forms air convection through the two ends and exhausts purified air out.  Bacteria and viruses floating in the air will be quickly killed once they enter the ultraviolet radiation layer.

Parallel Radiation on Upper Layer, Occupied Area

The product is installed at a minimum height of 2.3m.  The ultraviolet rays are emitted in a flat plane parallel to the ceiling using a built-in optical reflector plate.  The result is no ultraviolet rays below 2.1m above the floor (European and American safety certification RG0 standard for occupied space.)

Industrial Fan to Maximize Purification Efficiency

Internal fan draws air through the front inlet and exhausts purified air on the side, increasing air flow and purification rate.  The industrial fan has a lifespan of 70,000 hours.

Built-in PIR Sensor

  1.  A blue PIR indicator light is always on when the power is on.
  2. The PIR indicator light flashes every 1s when the PIR detects people in the room and shuts off the fan and UVC lamp.  After detecting no one within 2 minutes, the light and fan will be turned on automatically.  If the PIR detects people within two minutes after the light is turned off the two minute countdown resets and starts over.   If the UVC lamp is turned off or damaged the blue PIR indicator light goes out.
  3. PIR detection range >2m.

Patented Wave Louver Optical Control Technology

Louvers are designed with a wave pattern to assure parallel UVC irradiation in the upper air space for safety and to minimize the physical size of the device.

Built-in Aluminum Mirror Reflector to Improve Irradiation Efficiency

The built-in mirror finish aluminum reflector directs the ultraviolet light to the target irradiation area, greatly improving the intensity and of the ultraviolet light.

Easy Pull-Out Design for Lamp Replacement

UVC tubes are easily accessed for easy replacement by simply removing the screws at the end of the fixture, releasing both the lamps and power module.

Knowledge Base

What is UV-C advantage and disadvantage?

UVC lamps have thousands of hours life. This limits the need for consumable replacement and maintenance. UVC Disinfection Disadvantages. UVC light works only on surfaces within the field of view. If there are objects that prevent light from reaching the surface directly, the surface will not be disinfected sufficiently

Do UV lights really make indoor air quality better?

UV lights are an excellent defence when it comes to protecting your indoor air quality (IAQ) from bacteria. The quality of air inside your home is crucial to the health and comfort of your family, and this is true now more than ever!

Are UV-C lights worth it?

They’re inexpensive, effective, and easy to maintain, making them a no-brainer for anyone with a home HVAC system. Even if your HVAC system has a high-quality air filter, adding a UV light will help kill microorganisms and bacteria that might be small enough to slip through the filter.

Does air purifier with UV light work?

While UV air purifiers usually have a quiet operation and may be effective at removing bacteria from the air if a person uses them with HEPA filters, these devices can emit ozone. Additionally, unlike HEPA filters, UV air purifiers cannot effectively remove VOCs or other gases from the air.

Is ozone from UV-C light harmful?

Myth #6: UV-C disinfection produces ozone that can be very harmful. Some do. (But not ours). While at some wavelengths, the energy of UV light can produce ozone, this only happens at below 242 nm.

Which is better UV LED or UV-C LED?

If the application is a larger, higher flow system in continuous operation, UV lamps can have advantages to provide the best solution to end users. When it comes to compact, point-of-use appliances and purifiers, UVC LEDs provide lower costs of ownership and better alignment with design needs as compared to UV lamps.

What type of UV light kills mold?

The type of ultraviolet light that’s able to effectively get rid of mold is UV-C, which is a very short wavelength of UV light. Because of how beneficial UV light can be at the right amounts, this light is commonly used for disinfection purposes, which can include treating ballast water with UV disinfection.
