    Abstract: A filter element for a fluid has a filter medium arranged in annular shape about a longitudinal axis to be flowed through by the fluid to be filtered radially. A coaxial outlet socket is arranged at an end of the filter element facing upwardly in filtering operation. The coaxial outlet socket has a fluid outlet channel for filtered fluid and a venting channel that vents a clean side and/or a raw side of the filter element. The venting channel coaxially surrounds the fluid outlet channel radially and extends at least in sections thereof in axial direction. A filter system is provided with a filter head that has a fluid inlet conduit, a fluid outlet conduit for filtered fluid, and a venting conduit, wherein the filter element is suspended from the filter head.

    Abstract: A water drainage device for a filter module is provided with a valve housing that has a valve bore and a valve body received at least in sections thereof in the valve bore. The water drainage device can be transferred from a closed state, in which the valve body seals in relation to a valve seat of the valve bore, into an open state, in which the valve body is lifted off the valve seat, and transferred from the open state into the closed state. The valve body, upon transfer of the water drainage device from the closed state into the open state, moves linearly along the longitudinal axis of the valve bore and away from the valve seat along or at a slant to a direction of gravity in downward direction.

    Abstract: A filtration device is configured to be connected to an existing condensate drain line of a heating, cooling, and ventilation system. The filtration device is configured to collect metal and other debris as the condensate moves through the device and prevents the condensate drain line from getting a clog. When a clog is present or other issues affect a level of condensate to rise in the device and stop from draining properly, the device is configured to shut off the heating, cooling, and ventilation system. Alternatively, the device is configured to provide an alternate pipe for drainage.

    Abstract: According to one aspect of the disclosure, a bulk material handling method includes receiving bulk material on a first level of a system at receiving stations equipped with dust control filtration equipment, pneumatically conveying the bulk material up to a third level into bulk material storage hoppers, storing the bulk material, dispensing the stored bulk material to a bulk material transporter on the first level, including dosing the stored bulk material to an interior of a bulk material dosing hopper to create a bulk material dose, docking the dosing hopper with the transporter via a docking apparatus, and releasing the dose into the interior of the transporter, through a reduced pressure region in an internal volume of the docking apparatus. Other disclosed aspects include a related system, subsystems, and apparatuses.
