Pressure generating device and air filter having a correlated arrangement of magnets

A pressure generating device for producing a flow of a gas, the pressure generating device comprising:

• a housing;
• an air compressor disposed in the housing for producing the flow of the gas;
• and
• an air inlet defined in the housing, the air inlet in communication with the air compressor and structured to allow the passage of air therethrough to the air compressor for creating the flow of the gas,
• wherein the housing comprises a series of second magnetic field emission structures positioned therein or thereon at or about the air inlet, the series of second magnetic field emission structures positioned and structured to interact with a corresponding first series of magnetic field emission structures associated with a filtration assembly which is disposable at the air inlet.

A system for generating a flow of a gas, the system comprising:

• a pressure generating device comprising:
• a housing;
• an air compressor disposed in the housing for producing the flow of the gas;
• and
• an air inlet defined in the housing, the air inlet in communication with the air compressor and structured to allow the passage of air therethrough to the air compressor for creating the flow of the gas;
• and
• an air filtration assembly coupled to the housing at or about the air inlet, the air filtration assembly comprising:
• a filter portion formed from a filtration media;
• and
• a mounting portion disposed adjacent the filter portion, the mounting portion having a series of first magnetic field emission structures positioned therein or thereon, the first magnetic field structures oriented according to a code,
• wherein the housing comprises a series of second magnetic field emission structures positioned therein or thereon at or about the air inlet, the second magnetic field structures oriented according to a mirror image of the code, and
• wherein the filtration assembly is coupled to the housing by the magnetic attraction between the first magnetic field emission structures and the second magnetic field emission structures.
