Ventilation grilles are distribution elements suitable for air supply and exhaust. The ventilation grilles are suitable as termination distribution elements of HVAC systems. Some are also intended for installation on house facades, walls, plastering or directly into ducts. Thanks to the materials used, the grilles can be installed in indoor and outdoor environments. The ventilation grilles are made of stainless steel, wood or plastic.

Air disk valves are the most frequently used for air exhaustion from sanitary facilities, but can also be used for air supply. There are also available universal disk valves intended both for supply and exhaust air in our assortment. The valve is composed of an inlet cone and of an adjustable central disc enabling the air flow regulation.

The air flow through the disk valve can be adjusted by rotating the disc clockwise or anticlockwise. Dish valves operate with relatively low air flows from 30 to 200 m3/h, are manufactured in diameters of 80 to 200 mm. HVAC disc valves are made of either plastic or sheet steel, which is standardly varnished.

Diffusers are terminal HVAC elements for air distribution in commercial and residential buildings. The outlet surfaces of the diffusers are made of fixed (circular design guarantees an uniform flow of the supplied air in all directions) or adjustable profiled blades (by changing the angle of the air outlet, intensive mixing of the supplied air is ensured).

Residential diffusers are terminal distribution elements of HVAC systems used for air supply and exhaust in offices, hotels, family houses, etc. The residential diffusers are characterized by a simple air flow volume control and a modern design. The diffusers are made mainly of galvanized sheet metal painted in white RAL.

Long-reach nozzle diffusers are the most suitable distribution components for air distribution over long distances intended for premises such as sports and industrial halls, shopping centres, airports and other public areas. The nozzle diffusers are designed for installation in ceilings or in walls for the air supply. Our assortment includes fixed, adjustable, jet and multi-nozzle diffusers.

Vents are the most widely used distribution components in the industrial ventilation and are installed directly on the ducting - circular or four-sided. Vents / Grills are available in a single-row or double-row variant according to the number of rows of the adjustable blades. The single-row vents are mainly installed for exhaust air and the double-row vents/grills for its supply. On request, the vents can be equipped with several different types of regulation.

The wall grilles serve as a design distribution element for the extraction of air from the interior of department stores, theatres, garages, restaurants, etc. The wall ventilation grilles are designed to protect air distribution systems. The wall ventilation grilles can be supplied opaque or raster with a large airflow space. We supply various designs: with concealed mounting, with mounting frame, for flush mounting or with replaceable filter. On request, they can be painted according to the RAL colour chart for an additional charge according to the production series and the size of the ventilation grille.

The floor grilles are designed for floor mounting, for air supply and exhaust in ventilation systems. The floor ventilation grilles are made of aluminium with fixed blades. The blades are horizontal (PMA) or vertical (PMB) with spacings of 12.5 mm, 17.5 mm and 20 mm.
