chemical company the carulite 200 material is an extruded mixture of manganese dioxide and copper oxide and is typically used for ozone capture applications such as potable water off gas emissions office equipment emissions and corona treatment emissions according to an embodiment of the present invention the ozone catalyst 40 is capable of ozone removal efficiency approximately equal to greater than 99 in a configuration that results in a low pressure drop of 1 5 inches water column across the catalyst bed the expected lifetime of the catalyst material is approximately four years for indoor environments according to an embodiment of the present invention the air handling system further comprises a fan 50 the fan 50 is arranged in fluid communication with the ozone catalyst 40 and is configured to supply a differential pressure to move the air through the air flow path to the air outlet one having ordinary skill in the art will appreciate that the addition of the ozone catalyst 40 increases the power requirement for the fan 50 needed to draw air through the system the pressure drop through the air inlet the pre conditioning chamber and the wet electrostatic precipitator 30 are negligible compared to the 1 5 in wg needed for the.
