A ventilation assembly includes an air intake channel; a delivery channel; a generating device of an air stream between the intake channel and the delivery channel; a filtering section of the air stream to decrease, if not eliminate, the presence of particulate in the air stream. The filtering section includes a filter having a containment body provided with an intake opening and a delivery opening for the air stream passing therethrough, and air-tight bulkheads, arranged inside the containment body and shaped to force the air stream to collide therewith and with the inner walls of the containment body, the bulkheads and the containment body having a section portion suitable for being penetrated by the particulate in the air stream so as to retain it therein.

An air purification system for purifying atmospheric air has an ionization chamber that includes a needle arrangement. The needles create a dense and strong electric field when a high voltage is passed to them by the effect of dual charge ionization due to which the suspended particles in the polluted air get clumped together and fall. The second invention is an air monitoring system facilitating a two-way communication with external information sources. It contains gas sensors comprising of an ambient noise sensor, temperature and humidity sensor, and sensors to measure the amount of oxides of nitrogen, Sulphur, carbon and size of suspended particles in the air. The third invention is a theft protection module for the safe keeping of an air purification system.

An example of a species collection system includes a plurality of spaced-apart electrically conductive collectors and a plurality of emitter electrodes. In some embodiments, at least one emitter electrode is disposed between adjacent ones of the collectors. In some embodiments, the at least one emitter electrode extends beyond the collectors (e.g., in at least one dimension). Collectors may be aligned to a direction of gas flow from an outlet (e.g., of a cooling tower) to facilitate collection while minimizing interference with the gas flow. Different emitter electrodes may be maintained at different voltages. In some embodiments, collectors are attached to a collector frame and emitter electrodes are attached to emitter frame(s) that are electrically insulated from the collector frame. Collectors may span a gas outlet (e.g., of a cooling tower) and emitter frame(s) may be positioned outside of the collectors (e.g., and outside of a periphery of the gas outlet).

An air-inlet duct includes a particle separator and an agglomerator. The particle separator is configured to receive atmospheric air laden with particles and to direct the particles into a scavenge passageway while allowing the atmospheric air to move into a compressor passageway thereby reducing the number of particles that enter the compressor passageway. The agglomerator is configured to cause the particles to be attracted to one another and cluster together.
