FIELD: construction.
SUBSTANCE: exhaust facilities, preferably a vortex generator or exhaust facilities of vortex type, designed for an exhaust hood and made as capable of pulling air into the exhaust hood due to development of at least substantially circular, cyclonic, vortex or spiral motion comprise preferably a circular area with at least substantially diverting channels and/or channels with diverting elements, which are separated from each other by separating elements, preferably blades, designed for development of at least substantially circular, cyclonic, vortex or spiral motion. Besides, they comprise in at least one channel a fan for creation of at least substantially circular, cyclonic, vortex or spiral motion. Also an exhaust hood is described with exhaust facilities, as well as a method for air exhaust development, with the help of an exhaust hood.
EFFECT: increased efficiency of exhaustion, reduced number of parts and material, lower cost.
