Nozzle air distributors are intended for air distribution in-doors for distance using range of inlet air jet at the same time low noise level. As a rule, it is necessary in big size facilities ( parking, sport halls, exhibition centers, garages, storehouses, hangars, etc.). 
Nozzles mount in premises along walls. Inlet air jet from a nozzle moving to ventilated zone, changing a speed and temperature and deviates upwards (warm air) or downwards ( cold air). For increase range of air jet using joining of the separate nozzles in blocks. Optimum profile of nozzles provides low aerodynamic resistance and low noise level.
Features:
Nozzle air distributors have fixed nozzles. They are made of the anodized aluminum and painted in any color at will of customer according to RAL.
Types and sizes:
Nozzle air distributors are made seven standard sizes: from 100 to 400 mm.

Installation:
Directly in rectangular and round air ducts nozzle SD mount. In both cases are used unflanged folds through which fastening is realized by screws or rivets.
