Abstract: An air conditioner device having a housing or duct with an opening for exit of air and one or more rotatable flaps for adjusting air flow rate and angle exiting through the opening. An ionizer having an electrode is configured to ionize air exiting through the opening, and a cleaning pad is adapted to frictionally remove debris from the electrode consequent to rotation of the flaps without requiring manual operation by a user.

Abstract: An air conditioner device includes a housing or duct having an opening for exit of air and one or more rotatable flaps for adjusting air flow rate and angle exiting through the opening. Further provided are an ionizer having an electrode for ionizing air exiting through the opening, and a cleaning member adapted to automatically frictionally remove debris from the electrode consequent to rotation of the flaps without requiring manual operation of a user.

Abstract: Ionizing electrode with a cleaning mechanism including a solenoid with a bushing, a magnetic conductor, a coil housing a core having first and second ends, a return spring and a terminal for high voltage supply mounted on its body. The ionizing electrode is mounted inside the bushing and is configured so that an ionizing end and a non-ionizing end of the electrode protrude from the bushing, the non-ionizing end being fastened to the first end of the solenoid core.

Abstract: An ionizer includes a high voltage AC generator, and a planar ion emitter mounted on an insulating substrate and having an array of planar needles that protrude from an edge of the substrate. The high voltage AC generator may be actuated by a switch having a pair of mutually insulated planar contacts located near an edge of the insulating substrate and configured to be contacted by an electrically conductive coil spring. The coil spring is supported by a slider that is moveable toward the ion emitter from an initial position wherein the planar contacts are shorted by the spring so as to actuate the high voltage AC generator. Continued movement of the spring collects dust in its coils while breaking the switch contacts and de-energizing the high voltage AC generator.

Abstract: There is provided an airlock system utilizable with a protected Toxic Free Area (TFA) defined by an enclosure including spaced-apart first and second door arrangements, each door arrangement having an entrance and an exit and being divided by partitions into a plurality of sections, an airlock space coupled to, and bridging between, the first and second door arrangement, the exit of the second door being connectable to the protected TFA, while the first door arrangement having its entrance located outside the TFA, the arrangement being such that there is no direct airflow from the entrance of the first door arrangement to the exit of the second door arrangement. A method for facilitating entrance and egress from a Toxic Free Area (TFA) defined by an enclosure, without the danger of contamination of the protected TFA, is also provided.
