LeanProducts has developed Be-Free: three robot models for environmental sanitization, based on LED technology and UV-C manipulation. Surf, thanks to the 360 ° light emission, provides an environmental sanitation of the complete surfaces, Air consists in a ventilation system that forces the air inwards, where the UV-C LED system performs the sanitization. You can use it in the presence of people! Air Surf combines the characteristics of both models. LED lamps emit UV-C rays at a length of 270 nm, guarantee maximum germicidal action, without producing ozone or other chemicals.
