An air purifier capable of maximizing air purification capacity thereof while having a minimum installation area. The air purifier including a body, a suction unit arranged at a lower portion of the body, having a suction port to intake air, a discharge unit arranged at an upper portion of the body, having a discharge port to output the intake air, a blowing unit arranged within the body, to blow air from the suction unit to the discharge unit, and a filter unit arranged within the body, to purify the blown air, wherein at least one of the suction port and the discharge port has a surface that is inclined from a central axis of the body, wherein the filter unit has a filter surface, through which air passes, the filter surface being inclined from the central axis.

An air filtering system for an electrical enclosure including at least one filtering element arranged to filter an air flow injected into the inlet of the enclosure by a fan device, the system also including several independent filtering cells Ci, with i ranging from 1 to n and n greater than or equal to 3, each filtering cell Ci having a variable filtering capacity, each filtering cell Ci, with i greater than or equal to 2, is rendered active to filter a part of the air flow when the sum of the filtering capacities of the cells, ranging from C1 to Ci1, drops below a specific threshold.

An air purifier having an improved air purification capacity. The air purifier includes a base, a body arranged at a top of the base and having a cylindrical shape at a portion thereof, a suction unit arranged within the body and having a suction port, a discharge unit arranged within the body and having a discharge port to discharge air intook by the suction unit, a blowing unit arranged within the body to blow air from the suction unit to the discharge unit, and a filter unit arranged within the body to purify air blown by the blowing unit, wherein at least one of the suction port and the discharge port has a periphery defining a surface having an oval or ovoid shape inclined from a central axis of the cylindrical body portion, wherein the suction unit is pivotally coupled to the body.

A method and apparatus for an inline air purification system is described herein. An example apparatus includes a housing, a high-velocity air flow guide, a filter assembly, and a fan. The high-velocity air flow guide includes a first portion and a second portion. The first portion is configured to form a passage within the housing, and the second portion is configured to divert and accelerate air flow of the ambient air from the passage to a chamber of the housing. The filter assembly includes one or more filtering elements configured to receive the ambient air from the chamber. The fan is configured to draw the ambient air from the chamber through the filter assembly and to generate processed air from the ambient air. The housing is located in an HVAC duct, and occupies only part of the cross-sectional area of the duct. The remaining area of the duct accommodates bypass air flow to a primary fan in the HVAC system.

A fluid filtering device includes a casing, a fluid filter, an input pipe, an output pipe, an input pressure gauge, an output pressure gauge, and an automated fluid drain controller. The outer input and output ends of the input and output pipes, and the control output end of the automated fluid drain controller are located outside the outer surface of the plates, and the input and output gauge heads are mounted at the outer surface of the plates. By such arrangements, the pressure difference between input and output pressure can be checked readily, so as to maintain the filtering efficiency while reducing the risk of danger.

A hydrogen and oxygen (HHO) gas on-demand electrolysis fuel cell system for use with internal combustion engines is disclosed. This hydrogen on-demand (HOD) system integrates with the engine control module (ECM) or other control system that regulates the operation of an internal combustion engine in order to supply HHO to the engine and improve the engine's overall fuel efficiency. This system includes an electrolyte fluid reservoir outfitted with level, pressure and temperature sensors; a pump and heat exchanger; a uniquely-configured electrolyzer; and a filter. The combined engine and HOD system is controlled and regulated by an electronic control system (ECS) and a combustion control module (CCM). The CCM is installed on the engine such that it actively intercepts the electronic signals from the engine manufacturer's ECM to continuously coordinate the functions and operations of the HOD system and the engine.
