Direct replacement air filter with automatic pleated filter media advance
First Claim
1. A replacement media advancing air filter in an air handling unit with an air flow channel comprising:
- a housing having a substantially uniform thickness throughout the length and width of the housing and an at least one exposure slot;
an at least one filter media storage area, having an at least one media with an at least one unexposed pleated, folded filter media portion stored therein, the at least one unexposed pleated, folded filter media portion being pleated, folded, and stacked in and compactly held at least in part within the at least one filter media storage area;
an at least one motor coupled to a power supply and in communication with a controller, the at least one motor moving an at least one movement member that moves a portion of the at least one unexposed, pleated, folded filter media portion from a stored state in the at least one filter media storage area into the at least one exposure slot and exposes the unexposed pleated, folded filter media portion of the at least one filter media to the air in the air flow channel creating an exposed pleated portion of the at least one filter media, the exposed portion being moved in conjunction with an at least one supporting member and the movement of the exposed portion of the at least one filter media being based on output from the controller; and
a containment area, wherein the exposed portion of the at least one filter media is collected within the containment area.

Abstract
The invention is directed to replacement media advancing air filter in air handling units with a flow channel. The filter having a housing and an exposure slot with filter media storage area that has an unexposed pleated, folded filter media portion stored therein. The filter media portion being folded and stacked in and compactly held at least in part within the storage area. A motor is coupled to a power supply and in communication with a controller. The motor moves a movement member that moves a portion of the filter media from a stored state in the storage area into the exposure slot and is exposed to the air in the air flow channel creating an exposed portion of the filter media. The exposed portion is collected within a containment area as a further portion of media is moved into the exposure slot to replace the exposed portion therein.

15. A direct replacement air handler filter system within an air flow channel within an air handler unit comprising:
a housing having a substantially uniform thickness of between about one inch and three inches throughout its length and width and having an exposure slot there through and the housing being sealed throughout to prevent opening of the housing;
a motor coupled to a power source and in communication with a controller having an at least one sensor input or a timer; and
a filter media storage area located on one end of the housing, having a pleated, folded filter media folded and compactly stored substantially inside the filter media storage area, and an exposed filter media containment area located on an opposed end within the housing with the filter media extending therebetween in an operational state, the filter media being unstacked and an unexposed portion of the filter media being moved from said filter media storage area while being supported by an at least one support member with a fixed pleat spacing, across the housing and the exposure slot where it is exposed to air within the air flow channel which removes contaminants from the air and is then folded along its pleats into an exposed folded and pleated filter media portion and is further passed through to a containment area where the filter media is re-folded, collected, and compactly stored with the filtered contaminants, the motor being activated by said controller in response to input from the at least one sensor or based on a timed input from said timer and moving the at least one movement member to move the filter media across the exposure area.

16. A method of moving a pleated filter media within a uniform length and width, direct replacement air handler filter frame comprising the method steps of:
-
storing an unexposed folded, pleated filter media compactly within an at least one filter media storage area; engaging an at least one motor coupled to a power supply in communication with a controller and the at least one motor moving an at least one movement member; moving the at least one movement member by the at least one motor, and thereby moving an unexposed portion of the at least one filter media into an at least one exposure slot and exposing the unexposed portion of the at least one filter media to the air flow channel creating an exposed pleated portion of the at least one filter media, the exposed portion being paid out across an at least one supporting member with the at least one supporting member forcing the at least one filter media to fold at its pleats when placed into an air flow in the air flow channel and the paying out of the at least one filter media being based on output from the controller; and collecting in a containment area the exposed portion of the at least one filter media.
