The UV-FLOW .... C-WH is a controlled unidirectional flow device, with a powerful UV lamp inside and a narrow emission peak at wavelength of 253.7 nm. (nanometers).
There is also a parabolic, mirror bright aluminum surface, which generates UV rays parallel beams by reflection. These beams pass through a black honeycomb laminated grid that directs UV rays to form a unidirectional flow ("blade UV"). When installed according to the instructions, this device can be used above the presence of people while delivering a continuous dosage.
