The Air Surface Disinfection Unit (ASDU) will produce a high level of disinfection on all surfaces exposed to the Far-UV Sterilray™ lamp and will destroy the airborne viruses in the room in less than one second.

The 222nm lamps emit 10 to the 15th power photons per cm2 per second. (30,000 times the number of trees on earth).

It only takes one photon to destroy a covid virus floating in the air. The Far-UV Sterilray™ ADSU ceiling mount fixture design has been carefully conceived to provide direct high-level disinfection for air or surfaces in occupied rooms.

The ADSU can be set on a power level to fall below the FDA Threshold Limit Value (TLV) for human exposure.  

The Air Surface Disinfection Unit is ideally suited for higher nightly disinfection of surfaces on high power and can also provide disinfection between room occupation throughout the day.

Benefits : 

  • Rotating lamps and power supplies reduce the need for multiple units.
  • 30,000-hour lamp life warranty
  • Dry, chemical-free disinfection.
  • Green Clean-environmentally friendly.
  • Instant off with motion detectors.
  • No mercury or other dangerous materials in the lamp.
  • No labor required; operation controlled by room switch (delay timer).
  • Produces high-level disinfection of room air and exposed surfaces.
  • Destroys surface pathogens (MRSA, C.Difficile, VRE) that routinely compromise the healthcare environment.
  • Far-UV Sterilray™ produces up to 1000 times greater destruction than any other UV source.
  • Level of disinfection proportional to run time; 7 hours produces >6 log kill on floor level surfaces. (250-watt version)
  • Provides a high level of disinfection between room occupancy during the day and total disinfection each night.
