Model DGL-4


UV-DGL (Ultraviolet Duct Germicidal Lamp) is mainly installed in HVAC (heating, ventilating, and air conditioning) systems. Air that flows through the installed UV-DGL is subjected
to the ultraviolet rays coming from the germicidal lamp. These rays inactivate harmful bacteria
and viruses, disinfecting the air in seconds

The UV-DGL has been designed to provide sufficient ultraviolet germicidal dosage for both
air and surface. The recommended dosage will depend on the size of the air duct, airspeed, and temperature.
Our application specialists would be more than happy to help calculate and recommend the most suitable model for your application.



Low risk of ultraviolet rays over-exposure.



Able to run continuously without special monitoring.


Low Maintenance

Only requires an annual lamp change and scheduled cleaning.



Destroys harmful germs and bacteria, disinfecting the air in seconds.



Durable and lasting stainless steel and aluminium build.



Various models available to suit different duct size



Minimizes the risk of cross-contamination and exposure of occupants to contagious biological airborne contaminants.







      Model DGL-2 /DGL-4  

Generally used in the HVAC system of commercial buildings, the DGL-2 and DGL-4 helps to minimize and/or eliminate the growth of bacteria, mold and viruses, and to help limit the transmission of airborne diseases such as common cold, influenza and COVID-19.

In order for us to recommend a suitable UV-DGL model for your air duct, the below information is required:

  - Duct size
  - Length of duct where the UV-DGL will be installed
  - Air speed (cubic feet per minutes
  - Air temperature
High output germicidal lamps produce more UV watts than typical UV-C bulbs.

Robust Lampholder
Structure includes a fixed and spring-loaded holder that secures a single-pin lamp. The spring-loaded holder attributes to the convenience of replacing the lamp in a matter of seconds.

Heavy-duty Assembly
Built in aluminium Type 304 stainless steel for durability and extraordinary strength.
UV-DGL Ballasts
Specially designed to operate
UV lamps, the lightweight and
long-lasting Blaze UV-DGL ballasts
helps to save energy while producing
a high UV output as compared to
conventional ballasts.
Operation Indicator
Indicates the operation status of each germicidal lamp.
