VACUUM BREAKER A LEDGE ECO
SKU: FIS3990
Condition: NEW
A light-emitting diode (LED) is a semiconductorlight source that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons. The color of the light (corresponding to the energy of the photons) isdetermined by the energy required for electrons to cross the band gap of the semiconductor. White light is obtained by using multiple semiconductors or a layer of light-emitting phosphor on the semiconductor device.
A vacuum breaker is an attachment commonly placed on a bibcock valve or toilet or urinalflushvalve, that prevents water from being siphoned backward into the public drinking water system. This prevents contamination should the public drinking water
system's pressure drop.
