Disclosed is a germicidal device for air and for liquids, characterised in that it has five different operation modes, which comprises a series of particle-retaining filters (2, 14, 22, 25, 35) made of activated carbon and silver-ion fabric and through which a current of fluid passes at different pressures, propelled by motor-turbines (16, 17) towards labyrinth plates (5, 6). The plates surround a refrigeration compartment (9) containing emitters (7) of germicidal radiation, which refrigerate and purify gases such as ozone, preventing the consumption thereof and allowing same to be used as a germicidal reinforcement in the system. Purified air to be inhaled and exhaled air are carried through tubes (31, 32) between the device and a mask worn by the user, which are attached to the neck or head by means of retentive supports (37, 39, 40, 44, 45).

Disclosed is an air filtration system comprising a furniture item which may be a table; and at least one air filtration unit configured to integrate with the furniture item. In embodiments, the air filtration system includes at least one integrated receptacle configured to receive the air filtration unit and air channels in fluid communication with the receptacle, wherein the air channels are configured to channel filtered air from the air filtration unit.

An integrated autonomous air purification device for taking in polluted air, carrying it through the inside of the purification device where it passes through a set of filtering elements (1) that trap the dust particles contained in the air; ultraviolet-light lamps (2) that transform NO.sub.X and CO gases in the air into harmless compounds; an activated carbon filter (4) that traps and eliminates the volatile organic compounds and inorganic acidic gases; second filtering elements (5) that carry out a second filtering; and an extraction hood (6) configured to direct the air coming out of the second filtering elements (5) to at least one nozzle (7) that expels the air to the outside of the purification device.

A natural gas processing system is mounted on a mobile platform that is transported to a natural gas source, such as a well. The system supplies natural gas through multiple hose reels to operate multi-fuel engines for well field equipment such as pumps, compressors, and trucks. A coalescing filter removes contaminants from the natural gas. A generator powered by the natural gas supplies process electricity. A process control monitors and controls the natural gas processing system, including pressure, temperature, moisture, and flow sensors. A gas chromatograph will determine the chemical composition of the natural gas. A gas evacuation system removes gas from the hose reel assemblies in the event of an emergency. An emergency shutdown system will halt the process in the event of high liquid levels, a gas leak, fire, or gas composition out of specification.

The present disclosure is directed methods and apparatus of a V-Bank filtration system capable of maintaining desired air flow rates while effectively filtering the air. These methods and apparatus charge particles and then capture those particles in a filter medium. Once captured in the filter medium, micro-organisms are exposed to high energy electric fields that may degrade and ultimately destroy the captured micro-organisms. Electric fields generated within portions of the V-Bank filter apparatus may also be contained within the portions of the filter apparatus based on exterior parts of these portions being grounded at Earth ground potential. Magnetic fields (or electro-magnetic fields) associated with the generated electric fields may also be contained within the portions of the apparatus based on the exterior parts of these portions being grounded.

An air filtration apparatus includes an airflow powerhead assembly including a fan assembly and a vane assembly, a filter assembly, and a separator chamber housing inside of which the filter assembly is disposed. The separator chamber housing has a chamber inlet at a first axial side and a clean air outlet at a second axial side of the separator chamber housing opposite the first axial side. The filter assembly has a first axial end adjacent the chamber inlet and a second axial end adjacent the clean air outlet. The separator chamber housing includes at least one debris ejection slot extension configured to eject debris from an inner space of the separator chamber housing. The filter assembly includes a debris catch tray disposed at the second axial end, the debris catch tray having a debris ejection slot aligned with the at least one debris ejection slot extension.

An air cleaner is provided that includes a first air cleaning module including a first fan that generates an air flow toward a first discharge outlet from a first suction inlet; a second air cleaning module including a second fan that generates an air flow toward a second discharge outlet from a second suction inlet; a divider provided between the first air cleaning module and the second air cleaning module, the divider including a dividing plate space; and a printed circuit board (PCB) device provided in the dividing plate space.

The air-particle separation system is a dust handler that includes a main body with a misting module mounted thereon. The misting module includes air input pipes for receiving air with particles and a misting nozzle for soaking the particles within the air stream. The water particles and air are directed downwardly into a screen basket that is supported in a first chamber. A screen purging nozzle removes any particles stuck to the screen. Air is pulled through the system by a suction fan. An optional high-pressure fan may also be provided. The water, the water-soaked particles, and the air exit the screen basket and enter the first chamber and a second chamber. Air is removed from the chambers through the fan(s), while a drain in the bottom of the chambers drains the water and particles.

An air filter and a method of air filtration using the said air filter are described. The air filter may comprise a filter media layer adapted to capture and filter one or more impurities from air. The air filter may further comprise one or more acoustic wave generating means attached at one or more sides of the filter media layer. The one or more acoustic wave generating means may generate acoustic waves to be propagated into the filter media layer. The propagation of the acoustic waves into the filter media layer may facilitate the filter media layer to enhance the filtration efficiency of the air filter. The air filter may further comprise a pre-programmed chip to control the frequency of the acoustic waves generated. Further, air filter may comprise a battery adapted to supply power to the one or more acoustic wave generating means and the pre-programmed chip.

An air filter sensor is preferably attachable to an air filter and periodically checks the status of the filter based on pressure or air flow changes through the filter. An air filter cleaning system selectively or periodically cleans an air filter using a vacuum tube or tubes to maintain the filter in a substantially clean condition. A refrigerant sensor checks the refrigerant level in an air conditioning system and issues an alert if it drops below a desired threshold.
