PURO Defender - UV Air Duct
Installed inside air ducts, or in the final section of AHU (Air Handling Unit), PURO AIR Defender creates a UVGI barrier that inhibits the proliferation of viruses, bacteria, molds, and spores settling inside Air Conditioning Systems.
Defender disinfects the airflow running through an air duct and spores that settle inside air conditioning systems, reducing microbial load and the spread of hazardous pathogens inside buildings.
In AC systems, an unsafe biofilm often covers all inner surfaces. Microorganisms proliferate due to favorable conditions such as temperature changes, high humidity, and darkness. Defender inhibits the creation of this biofilm, increasing Indoor Air Quality (IAQ) and comfort. The Defender is important not only for IAQ and health but for a cleaner, more economically efficient AC system, with less operative and maintenance costs. With Defender, you obtain continuous disinfection of your AC system without the use of expensive and polluting chemicals.
What is UV-C?
Light in a broad sense can be divided in visible, infra-red, and ultraviolet rays. Ultra-violet rays (invisible) can be classified in:
- UV-A (with tanning properties)
- UV-B (with therapeutic properties)
- UV-C (with germicidal properties)
The germicidal effects of UV-C radiation destroy the DNA of bacteria, viruses, spores, fungi, molds, and mites, inactivating their growth and proliferation.
UVGI technology is a physic disinfection method with a great cost/benefit ratio. It’s ecological, and, unlike chemicals, it works against every microorganism without creating any resistance.
- Selective UV-C PURO AIR lamps (emission peak at 253.7nm) high efficiency, ozone free, pure quartz
- Body in stainless steel AISI 304
- All materials are tested for resistance to intense UV-C.
- Powered by electronic ballasts specific for PURO AIR UV-C lamps
- Powered by 110V or 240V
- Hour Counter and LED Indicator (optional)

The Defender family includes a range of flange modules with two “U” lamps of different sizes (from 20 to 50 cm) and power ratings (from 70W to 190W) protected by a stainless steel grid.
Compact size and onboard commands allow easy application in existing air conditioning systems. Easy to install: insert lamps within air ducts through two holes using the drilling template provided, and screw flange on the external channel.
Ballasts are inserted directly inside the case and are specific to PURO AIR Duct UV-C lamps, optimizing their performances and durability.
Defender is made with high quality and extremely durable components and works perfectly in difficult operating conditions of high humidity, low temperatures, and more.
