AIR CLEANER TO REMOVE AIR CONTAMINANTS FROM AIRFLOW Russian patent published in 2015 - IPC B01D45/10 

FIELD: process engineering.

SUBSTANCE: set of inventions relates to air cleaner for removal of air contaminants from airflow, for example, for purification of gas released or sucked by slot-machines and to said slot-machines. Air cleaner comprises filtering device including at least one filtering ply retained by filter holder in said airflow, in fact, perpendicular to the main direction of said flow. Note here that said filtering ply is composed of several rod-like filtering elements for adsorption or absorption of air contaminants. Filtering ply features the boundary extending along the extreme outer filtering element and/or ends parts of such elements. Additionally, said air cleaner comprises mounting frame that closed said filtering ply over its edges. Said mounting frame includes recess for insertion completely overlapping of design area of said filtering ply if seen in direction of airflow. This allows insertion of said ply into said mounting frame and remove it therefrom in direction perpendicular to the plane defined by filtering ply. Note here that several rod-like filtering elements are interconnected by retaining element. Said recess does not clamp said filtering ply over the entire perimeter. Note here that opposite ends of rod-like filtering elements or retaining element are press-fitted into insertion recess. Slot-machine for gambling comprises housing equipped with at least one gambling data display, instruction input panel, electronic control unit for control over said display. Note also that said electronic control unit is arranged inside said housing along with said air cleaner.

EFFECT: higher efficiency of contaminants removal.
