The ZLV NG fresh air distributor for fresh air distribution across a large distribution radius, even at minimal air flow rate. ZLV NG has been developed for equal pressure ventilation and negative pressure ventilation as well as for compact stable buildings (so-called mono-blocks). The wave structure in the nozzle ensures optimum fresh air regulation even with a minimal opening. This system can also be employed with equal pressure systems (additional fresh air fan required) where the discharge stables have large openings and in areas where leaks and wind influence come into play. The optionally available air conduction unit partially deflects the incoming fresh air at the distributor plate.
