PROBLEM TO BE SOLVED: To provide an inexpensive ceiling exhaust system exhibiting excellent exhausting power. SOLUTION: The ceiling exhaust system comprises a plurality of elongated exhaust sections 3 juxtaposed on the ceiling C at an interval to perform suction at respective parts in the longitudinal direction wherein an exhaust guide section G having a lower surface serving as an exhaust guide plane S is provided between adjacent exhaust sections 3 along the longitudinal direction thereof. The exhaust guide plane S has a ridge part Sr extending along the longitudinal direction of the exhaust section 3, and a pair of left/right inclining guide planes Ss extending from the ridge part Sr toward the left and right exhaust sections 3 wherein each inclining guide plane Ss is inclining so as to ascend toward the exhaust section 3. |
