Abstract: 1. Pentapost type air handling unit casing comprising panels arranged side by side and perpendicularly, and side profiles embodied between the perpendicular panels and middle profiles embodied between side by side panels characterized in that said side profiles (2) comprises at least two joined preferably diagonal partitions having a predetermined height and width and said middle profiles (3) having the same thickness with the side panels are provided with steps on two opposite directions around circumference of the said middle profiles (3). 2. Pentapost type air handling unit casing according to claim 1, characterized in that said steps of middle profile (3) comprise lengthwise steps on which panels are fastened are formed on the exterior side of the middle profile (3) and widthwise steps providing side profile (2) connection are formed on interior middle profile side. 3. Pentapost type air handling unit casing according to claim 1, characterized in that said two partitions of the side profiles (2) are preferably embodied diagonally with respect to each other. 4. Pentapost type air handling unit casing according to claim 1, characterized in that at the corners of the said casing, corner pieces (4) are located for connecting said side profiles (2). 5. Pentapost type air handling unit casing according to claim 4, characterized in that said corner pieces (4) have preferably three legs for housing associated side profile therein. 6. Pentapost type air handling unit casing according to claim 1, characterized in that self-drilling screws (9) are embodied for providing connection between the side profiles (2) to panels, and middle profiles (3) to panels. 7. Pentapost type air handling unit casing according to claim 1 and 6, characterized in that said self-drilling screws (9) are located inside plastic bushings (10) having a cylindrical embodiment and providing connection between the panels and side, middle profiles. 8. Pentapost type air handling unit casing according to claim 7, characterized in that said bushing (10) is furnished with two elastic nails (11) movable in the direction of the bushing radius. 9. Pentapost type air handling unit casing according to claim 7, characterized in that top surface of the bushing (10) appearing on exterior panel surface is covered by a lid (21) for protecting screw from corrosion. 10. Pentapost type air handling unit casing according to claim 1, characterized in that said side profile (2) is preferably a steel strip while the middle profile is preferably two steel skins, an insulation material therebetween or steel strip having bottom and top lids. 11. Pentapost type air handling unit casing according to claim 1, characterized in that said middle profile (3) is a steel strip and provided with lower and upper lids. 12. Pentapost type air handling unit casing according to claims 1 and 11, characterized in that said side profiles (2) are sewn or preferably welded from lengthwise edges to each other. 13. Pentapost type air handling unit casing according to claim 1, characterized in that rubber gaskets (19) having two different lips thereof for increasing air leakage resistance in case of positive and negative pressure difference between the casing and surrounding are located between the panels and side (2), middle profiles (3).
