Forming the delivery jets of different decay rate

Modem air distributive devices allow to form the different types of stream with parameters that can differ and by fading rates. Among the wide variety of air distributor devices, on principle of action will consider a few especially interesting. All transferred methods provide the necessary method of serve of air in every concrete case, what provide the normative parameters of ventilation. The construction of air distributive which will unite all higher marked stream depending on requirements to organization of ventilation is offered.
