Model 66087 Ozone Eater and 66090 Replacement Filter.
Our Ozone Eater converts ozone back into oxygen, making your work environment ozone free and safer! It is the best solution if you do not have access to a ventilation port or the outside. It works with any Oriel® Research Housing up to 1000 W, filtering the ozone from the lamp's cooling air.Connect one end of the hose to your lamp housing fan and the other end to the Ozone Eater. The cooling air is collected and passed through catalytic filters that convert the ozone back into oxygen. The 66087 Ozone Eater comes with a filter module, an 8 ft. (2.4 m) long flexible hose, two catalytic filter elements, and a fan.
Ozone, O3, a toxic substance, is a molecular form of oxygen produced by a photochemical reaction between UV radiation and oxygen in the air. In low concentrations, ozone irritates the eyes and mucous membranes. The tolerance of ozone and physiological reaction to it varies with the individual. The maximum concentration allowed by OSHA for personnel exposed over an 8-hour period is 0.1 ppm.Lamps that have output below 242 nm (pulsed and CW) produce ozone. The higher the lamp UV output, the greater the rate of ozone production. With fan-cooled housings, ozone is exhausted through the lamp housing fan. With convection-cooled housings (like our popular Series Q), the ozone leaks out of the housing.
Since the material in the filter elements interacts chemically with a portion of the ozone, the elements must be periodically replaced, their exact lifetime dependent upon the ozone concentration in the airstream; at 4 ppm the elements will last ~4000 hours.
If your lab has a light source, it is a good idea to have an ozone test kit on hand. It measures the concentration of ozone in a sample of air from a range of 0.05 to 5 ppm. The kit consists of a hand operated pump and ten detector tubes. The piston-type pump draws a sample of air through the detector tube. The tube indicates the concentration of ozone by the length of color change on the tube. The detector tubes have a minimum two-year shelf life.
