An apparatus for the cleaning of crankcase gas from an internal combustion engine includes a housing and a separation chamber for the crankcase gas with a centrifugal rotor arranged for the cleaning of the crankcase gas in the separation chamber. The centrifugal rotor includes a drive shaft extending into a drive chamber of the apparatus. A turbine is connected to the drive shaft. A nozzle is arranged to receive pressurized liquid from the combustion engine and to direct the pressurized liquid in a jet from a nozzle opening against the turbine for rotation of the centrifugal rotor. An adapter element is configured such that the apparatus is mountable onto the combustion engine with a drive liquid passage in communication with the nozzle. The nozzle is integrally formed with the adapter element with a nozzle passage having a conical shape which converges in the flow direction towards the nozzle opening.

A filter module and an air purifier according to an aspect of the present disclosure include a supply roller and a recovery roller, a filter wound and installed on the supply roller and the recovery roller, so that it can be used without replacing and cleaning the filter module for a long period of time by allowing a section used in the filter to be recovered in the recovery roller, and also a section not used in the filter to be supplied from the supply roller.

The present invention relates to a withdrawal plate suitable for an apparatus for withdrawing a sprayed paint to solve a failure of a painting facility and a contamination problem due to paint sludge, which includes: a square frame constituted by left and right side frames 91, an upper frame 92, and a base frame 93; and slats 94 arranged at a predetermined interval within the square frame, in which the left and right side frames 91 facing each other are included in one direction, and the slat 94 is fixed the left and right side frames 91 in an oblique state so that a front is lifted up and moves down backwards when viewed from the side, and multiple slats are consecutively arranged at a predetermined interval in a vertical direction.

Economical, easy to install and use, and disposable, air filter for an HVAC system. The filter is quasi-universal with respect to the size of the air intake vent over which it can be deployed, and it requires less frequent replacement of filter material than is common with typical throwaway (box-type) air filters. When replacement of filter material is needed, the replacement can be done with less or no direct handling of or exposure to the dirty filter material. In use, the filter maintains relatively consistent cleanliness of the filter material by automatic, periodic scrolling of the filter material to replenish the filtering surface.

A filter mounting assembly for use with a structure having front and interconnecting side faces surrounding an air intake opening. The assembly includes at least one “L” shaped member adapted to be secured to either of the front or side faces of the structure on either side of the intake opening. A track is secured to each of the members so that an interior accessible channel of each track is arrayed in opposing fashion on opposite sides of the opening forward of the front intake face. A plurality of rollers are contained within each of the rails, the rollers each further including a forward extending hook portion projection from the interior track channels. A covering is provided having a plurality of side edge proximate located eyelets, the hook portions engaging through the eyelets for supporting the covering over the opening.

A housing for a centrifugal separator is disclosed, wherein the centrifugal separator is configured to separate a liquid phase from crankcase gases of an internal combustion engine using a rotor. The housing includes a housing body forming a separation chamber, an opening in the housing body, a bearing retainer arranged at the opening, and a bearing inserted into the bearing retainer. The bearing is configured to receive a rotor shaft extending into the separation chamber. The bearing retainer includes a bearing seat portion provided with a number of plastically deformed zones retaining the bearing in the bearing retainer. A centrifugal separator and a method of retaining a bearing of a rotor shaft in a housing for a centrifugal separator are also disclosed.

A modular filter for ventilation air vents comprises a filtering fabric roll (1) housed within a casing provided with anchoring means (13) engaging the surface (S) of the container which has the air intake port (B) to be filtered; the casing has a slot (9) for extracting the filtering fabric (T), and has a casing (4) comprised of a shaped wall (5) enclosed at the ends by covers (10, 40, 44, 51) or end supports (7, 47) of this wall having a shape corresponding to the shaped wall (5) and maintaining a longitudinal slot (9) at the front edges of the shaped wall to allow the passage for the extraction of the front (F) of the filtering fabric (T) unwound from the filtering fabric roll (1); at least one screw stay rod (8, 54) is placed between two covers (51) or end supports (7, 47) of the shaped wall and is tightened to define the proper distance between the two end supports or covers (51), by tightening the end supports (7, 47) or covers (51) to the shaped wall (5), one at each end, to close the access to the casing, and containing the filtering fabric roll (1) floating and free to rotate when the filtering fabric is dragged from the outside of the modular filter.

Various methods for producing the shaped wall (5) and finalizing the casing (4) of the modular filter are indicated.
