Dynamic DYN-7-100-DRU-12 UV System. The Dynamic Series 2 MultiVoltage Dual Remote UVC System, model DYN-7-100-DRU-12 is a whole house air purification system that installs directly into the central heating and cooling system ductwork or plenum. The DYN-7-100-DRU-12 includes a 100 Watt power supply and has two 12” germicidal UVC lamps.|n|With ultraviolet light, microwatts translate to effectiveness. Each DYN-7-100-DRU-12 UVC lamp produces a very high output of 180 microwatts which is significantly higher than many other UVC lamps. The high-intensity Dual-Radiant UVC “H” Lamps disinfect the air by neutralizing airborne pathogens such as bacteria, viruses, and mold. According to the EPA, the combined use of filtration and germicidal UVC light is an effective means of preventing the distribution of airborne viruses and pathogens in occupied spaces. For maximum effectiveness, the DYN-7-100-DRU-12 includes two UVC Lamps that can be mounted on both the supply and return sides of the HVAC system. Each system is shipped with two duct mounting plates and a magnetic bracket for in-duct mounting. UVC lamps must be replaced every 2 years.
