A pollution monitoring system and a method is disclosed. The pollution monitoring system comprises an on-board sensor unit having a plurality of sensors, configured for monitoring air quality by measuring pollution data in the air and a power control unit connected with the on-board sensor unit for controlling the operation of the on-board sensor unit. The pollution monitoring system further comprises microcontroller configured for generating control signals to be transmitted to the power control unit for controlling operation of on-board sensor unit. The microcontroller is configured for receiving information from a base station regarding operation of the on-board sensor unit. Further, the pollution monitoring system comprises an air purification unit configured for receiving the pollution data from the microcontroller and enabling activation or deactivation of the air purification unit based on comparison of the pollution data with predefined threshold values.

A filter support for mounting an air cleaning device includes an access panel, at least one support member extending from the access panel, and a latch mounted to the access panel. The latch is operable to selectively couple to the air cleaning device.

An air filtration system is disclosed. The system comprises an air conduit having an inlet and an outlet, a self-contained electric power source, an electrically powered fan, an air filter located transversely across said air conduit, and an air boundary containment nozzle at the outlet of the air conduit. The nozzle has an outlet diameter of between about 0.5 centimeters and about 4 centimeters. The nozzle minimizes the mixing of the unfiltered ambient air with the filtered air directed to the wearer.

A vacuum cleaner that includes a suction source configured to generate a suction airflow, a dirt collector in fluid communication with the suction source and configured to separate debris from the suction airflow and the dirt collector is configured to store the debris separated from the suction airflow. The vacuum further includes an infrared sensor operable to output a signal corresponding to a distance to an amount of debris stored in the dirt collector, a controller that receives the signal, and the controller is operable to determine a fill level stored in the dirt collector based on the signal. A visual display displays the fill level stored in the dirt collector.

A pillar shaped honeycomb structure includes: a porous partition wall that defines a plurality of cells, the cells forming flow paths for a fluid, the cells extending from an inflow end face to an outflow end face; and an outer peripheral wall located at the outermost circumference. At least a part of surfaces of the partition walls has a surface layer, and the surface layer includes magnetic particles and has permeability.

A liquid separator for separating liquid out of a gas/liquid mixture, including an inlet, an outlet, a flow path connecting the inlet to the outlet and at least one separating device arranged in the flow path, the liquid separator being designed and embodied with simple structure and a compact construction to enable reliable separation of liquids in such a way that the separating device has a fabric portion for liquid separation through which the flow path passes, the fabric portion being arranged at an angle of 1° to 15° relative to the main flow direction in the separating device.

A compressor system includes a compression module having an inlet for receiving air; and a filter housing in fluid communication with the compression module. The filter housing is constructed to house a filter, the filter having a sealing feature disposed at a first end of the filter and having an engagement feature disposed at a second end of the filter opposite the first end. The filter housing includes a trap door constructed to contact the engagement feature, and constructed to drive the engagement feature in a direction parallel to an axis of the filter toward the sealing feature and urge the sealing feature into sealing engagement with the filter housing.

An air filter element inlcudes a first end and a second end located opposite to the first end in relation to a longitudinal direction of the air filter element. The air filter element is configured for axial insertion into a filter housing with the first end leading the axial insertion. The air filter element inlcudes a gripping structure at the second end, the gripping structure comprising an external surface accessible for interaction by a tool to facilitate removal of the air filter element from the filter housing. The gripping structure is also configured to, during insertion of the air filter element into the filter housing, radially align the air filter element in the filter housing.

The present invention relates to filter housing (12) of a filter (10) for a fluid and a filter (10). The filter housing (12) comprises a housing body (24), which is comprising at least one openable installation opening and at least one housing cover (26), which is configured to close off the at least one openable installation opening, and at least one fastening and/or locking device (186), which is configured to secure the at least one housing cover (26) in its closed position in the housing body (24). The housing body (24) comprises an element receptacle configured to receive, through the at least one openable installation opening at least one filter element. At least one fastening and/or locking device (186) has at least one U-shaped bracket element (188), whose arm sections (206) are connected to a cross beam (192), and at least one eccentric element (187) which is mounted rotatable with respect to a rotation axis (190) on the cross beam (192). The at least one bracket element (188) can pivot with respect to a bracket pivot axis (196) such, that the cross beam with the at least one eccentric element (187) is pivotable on the side of the housing body (24) with the at least one installation opening. In a closed position the at least one eccentric element (187) is engaged with the at least one housing cover (26) and the at least one bracket element (188) grips around the housing cover (26) such, that a part of the housing cover (26) is located between the arm sections (206) of the bracket element (188).
