Aluminium ventilation grilles | ventilation.ro (page 3 of 4)

Anodised aluminium ventilation grilles are the visible elements of any ventilation and air conditioning system: they control how air is distributed and directed within a space, directly influencing temperature uniformity, air velocity at occupant level and the noise level of the installation. Anodised aluminium provides superior corrosion and moisture resistance, low weight and a neat aesthetic finish — qualities essential for an element permanently installed in the ceilings and walls of a building.

A ventilation grille incorrectly sized for the actual system airflow produces aerodynamic noise, uncomfortable draughts and non-uniform temperature distribution. Correct selection requires calculating air velocity through the free area — below 2.5 m/s for occupied spaces — and matching the dimensions to the existing ductwork.

Our range covers all the types needed for a complete system: ceiling grilles for air distribution through false ceilings in offices and commercial spaces, swirl diffusers for maximum comfort in spaces with demanding thermal requirements, external grilles weatherproof with insect mesh, floor grilles for systems with underfloor technical distribution, single and double deflection grilles with adjustable blades, ventilation valves for precise adjustable extraction, transfer grilles for make-up air between rooms and gravity grilles with self-closing anti-draught blades.

Custom sizes and RAL colours

The standard range covers the most widely used dimensions in residential and commercial installations. For projects requiring non-standard dimensions — large surfaces, special formats or integration into specific architectural systems — grilles can be manufactured to the exact project dimensions, retaining the same materials and construction quality.

The standard finish is silver anodised aluminium (natural). On request, grilles can be powder-coated in any RAL colour — white RAL 9010 or RAL 9016 for integration into white ceilings and walls, anthracite RAL 7016 or black RAL 9005 for modern interiors, or any other RAL colour to match the space colour scheme.
