The product consists of a metal grille with hinged metal louvers. When exposed to excess pressure, the louvers fit tightly against the grille and stop the excessive air flow caused by the shock wave. Once the excess pressure has stabilized, the louvers return to their normal position by spring action. The angle of the blades to the plane of the grille can be adjusted from 0° to 45° using the corresponding screws. By default, the product is coated with RAL 5007 Muar powder paint. The colour can be changed according to RAL on request. The grilles are designed to operate in a temperate climate of the 2nd placement category (Y2) in accordance with DSTU 15150. It is allowed to install the MZR grille outdoors provided that a protective cover KPZ is used, which can be operated in moderate (Y) climates of 1st placement category (Y1).
