Abstract
An air-transporter conditioner device includes a housing defining an inlet and an outlet. An electro-kinetic system is disposed in the housing to create an airflow moving from the inlet to the outlet. A timer measures a time period corresponding to the electro-kinetic system and causes an indicator light to illuminate when the measured period reaches a threshold. An arc sensing circuit detects arcing between the first and second electrode arrays of the electro-kinetic system. The electro-kinetic system is turned off in response to arcing being detected by the arc sensing circuit. An indicator light can also specify that arcing has been detected.
