Facade Grilles for Outdoor Installation

Ventilation grilles for outdoor installation are specially designed for suction of fresh air or discharge of the exhaust air from ventilation and air conditioning systems and installation directly on the facade or on building enclosing elements. The aerodynamic pressure drop is low and the slats are mounted so that they do not allow raindrops to enter. The air flow rate of single ventilation grille can be from 100m3/h up to over 1000m3/h (27l/s – over 278l/s).

Possible implementation of insect net (+ IN) at the customer’s request. Standard painted in white (RAL9010), but at the customer’s request can be painted in any RAL color.
  • TANGRA VJR – External revisory ventilation grille made of aluminum profiles and aluminum frame.
