A side dump trailer that empties to either side includes a generally rectangular chassis with front and rear axles, each having a pair of wheels, with the front axle secured to the chassis via a swivel connection to allow steering of the trailer with a tongue. The chassis has an elevated rectangular open top box trapezoidal in cross section with a closed bottom supported on the chassis and a larger open top. The box is fastened to the chassis by four pairs of cylindrical bushings, one of each pair fastened at each corner of the box and the other of each pair fastened to the chassis. The bushing pairs each receive a removable connector pin. Removing the connector pins from bushings on one side of the box allow the box to pivot and dump to the opposite side of the trailer.

A humidifying module according to the claim 1, wherein said inner flow passage is formed to have a cylinder shape, and said protrusion is formed to have a circular cone shape. 3. A humidifying module according to the claim 1, wherein said outlet comprises a plurality of through holes bored in a circumferential wall of said inner flow passage proximate said end wall, wherein at least one through hole of said plurality of through holes is positioned between a tip of said protrusion remote from said end wall and said end wall. 4. A humidifying module according to the claim 2, wherein said outlet comprises a plurality of through holes bored in a circumferential wall of said inner flow passage proximate said end wall, wherein at least one through hole of said plurality of through holes is positioned between a tip of said protrusion remote from said end wall and said end wall. 5. A humidifying module according to the claim 1, wherein said protrusion comprises a plurality of plates stacked on top of each other and having a diameter that gradually decreases in a direction from said end wall toward said inlet of said inner flow passage, wherein said plates are circular shaped. 6. A humidifying module according to the claim 1, wherein said protrusion comprises a plurality of plates stacked on top of each other and having a width and height that gradually decrease in a direction from said end wall toward said inlet of said inner flow passage. 7. A humidifying module comprising: a plurality of hollow fiber membranes grouped together to form a hollow fiber membrane bundle, wherein a moisture exchange is performed across a thickness of each hollow fiber membrane between fluid streaming within an interior of said each hollow fiber membrane and along an exterior of said each hollow fiber membrane; a hollow, cylindrical shaped inner flow passage inserted within said hollow fiber membrane bundle, wherein a longitudinal length of said inner flow passage is shorter than a longitudinal length of said hollow fiber membrane bundle, and wherein said inner flow passage includes: an inlet and an outlet through which the fluid passes, and an end wall located near said outlet; and a protrusion disposed at said end wall wherein an inner cross-sectional area of said inner flow passage gradually decreases in a direction taken from an inlet of said inner flow passage toward said end wall. 8. A humidifying module according to the claim 7, wherein said outlet comprises a plurality of through holes bored in a circumferential wall of said inner flow passage proximate said end wall, wherein at least one through hole of said plurality of through holes is located between a tip of said protrusion remote from said end wall and said end wall. 9. A humidifying module according to the claim 7, wherein said protrusion has a circular cone shape. 10. A humidifying module according to the claim 7, wherein said protrusion comprises a plurality of plates stacked on top of each other and having a diameter that gradually decreases in a direction from said end wall toward said inlet of said inner flow passage, wherein said plates are circular shaped. 11. A humidifying module according to the claim 7, wherein said protrusion comprises a plurality of plates stacked on top of each other and having a width and height that gradually decrease in a direction from said end wall toward said inlet of said inner flow passage. 12. A humidifying module comprising: a plurality of hollow fiber membranes grouped together to form a hollow fiber membrane bundle, wherein a moisture exchange is performed across a thickness of each hollow fiber membrane between fluid streaming within an interior of said each hollow fiber membrane and along an exterior of said each hollow fiber membrane; a hollow, square shaped inner flow passage inserted within said hollow fiber membrane bundle, wherein a longitudinal length of said inner flow passage is shorter than a longitudinal length of said hollow fiber membrane bundle, and wherein said inner flow passage includes: an inlet and an outlet through which the fluid passes, and an end wall located near said outlet; and a protrusion disposed at said end wall wherein an inner cross-sectional area of said inner flow passage gradually decreases in a direction taken from an inlet of said inner flow passage toward said end wall. 13. A humidifying module according to the claim 12, wherein said outlet comprises a plurality of through holes bored in an outer wall of said inner flow passage proximate said end wall, wherein at least one through hole of said plurality of through holes is located between a tip of said protrusion remote from said end wall and said end wall. 14. A humidifying module according to the claim 12, wherein said protrusion has a circular cone shape. 15. A humidifying module according to the claim 12, wherein said protrusion comprises a plurality of plates stacked on top of each other and having a diameter that gradually decreases in a direction from said end wall toward said inlet of said inner flow passage, wherein said plates are circular shaped. 16. A humidifying module according to the claim 12, wherein said protrusion comprises a plurality of plates stacked on top of each other and having a width and height that gradually decrease in a direction from said end wall toward said inlet of said inner flow passage.
