An air ioniser (or negative ion generator or Chizhevsky's chandelier) is a device that uses high voltage to ionise (electrically charge) air molecules. Negative ions, or anions , are particles with one or more extra electrons , conferring a net negative charge to the particle.
This is the most common type of ozone generator for most industrial and personal uses. While variations of the "hot spark" coronal discharge method of ozone production exist, including medical grade and industrial grade ozone generators, these units usually work by means of a corona discharge tube or ozone plate.
The term oxygen generator is a misnomer in that the oxygen is not generated as it is with a chemical oxygen generator, but rather it is concentrated from the air. Non-medical oxygen concentrators can be used as feed gas to a medical oxygen system, such as the oxygen system in a hospital, though governmental approval is required, such as by the ...
Ozone generators are designed to produce ozone and are sometimes sold as whole-house air cleaners. Unlike ionizers, ozone generators are intended to produce significant amounts of ozone, a strong oxidant gas which can oxidize many other chemicals. The only safe use of ozone generators is in unoccupied rooms, utilising "shock treatment ...
Ozone production [6] Insulation damage; Possible distress in animals that are sensitive to ultraviolet light [7] Electrical components such as transformers, capacitors, electric motors, and generators: Corona can progressively damage the insulation inside these devices, leading to equipment failure. Elastomer items such as O-rings can suffer ...
The generators are usually ignited by a firing pin, and the chemical reaction is usually exothermic, making the generator a potential fire hazard. Potassium superoxide was used as an oxygen source on early crewed missions of the Soviet space program , in submarines for use in emergency situations, for firefighters , and for mine rescue .
In a sweeping two-year investigation, The Associated Press found goods linked to U.S. prisoners wind up in the supply chains of a dizzying array of products from Frosted Flakes cereal and Ball ...
NO x reacts with volatile organic compounds in the presence of sunlight to form ozone. Ozone can cause adverse effects such as damage to lung tissue and reduction in lung function mostly in susceptible populations (children, elderly, asthmatics). Ozone can be transported by wind currents and cause health impacts far from the original sources.
