Vents / Grilles

Vents / Grilles

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.

VNM

VNM

The VNM vents for four-sided ducts are end HVAC elements designed for air supply and exhaust in air-conditioned, ventilated and heated rooms. The VNM grille consists of a rectangular frame in which are mounted one or two rows of adjustable blades with a spacing of 20 mm (single-row or double-row grille) with a control or mounting frame. It is also possible to supply a diffuser with R1 control with counter-rotating blades, R2 with a tilting arm of the directing blades and R3 with a fixed and sliding control bar parallel to the grille frame. On request there can be available controls R5 with a large tilting blade and R6 with a fixed and sliding control bar placed obliquely to the grille frame.

The VNM four-sided diffusers are made of aluminium profiles with mounting frame without brackets UR, with mounting frame with brackets for threaded rods UR1 or with mounting frame with brackets for flush mounting UR2. Another design of the VNM diffusers that must be selected is the possibility of concealed mounting (spring clips) or mounting by means of screws S and arrangement of blades A (horizontally) or B (vertically). The tightness of the vents is ensured by sealing around the perimeter. The vents are designed for environments protected against weather influences with the classification of climatic conditions of class 3K5, without condensation, icing, ice formation and without water and from sources also other than rain according to EN 60 721-3-3 zm.A2.

On request, it is possible to supply frames of the vents and of the rotating blades with baking varnish according to RAL.

 

VNKM

VNKM

The VNKM diffusers for circular air ducts are end HVAC elements intended for air distribution in air-conditioned, ventilated and heated spaces. The VNKM distribution grille assembly consists of a rectangular frame in which one or two rows of rotating blades are mounted (single-row or double-row grille). It is also possible to supply a vent with the R1 control with counter-rotating blades, R2 with a tilting arm of the directing blades and R3 with a fixed and sliding control bar parallel to the grille frame. On request, there can be available controls R5 with a large tilting blade and R6 with a fixed and sliding control bar placed obliquely to the grille frame.

The VNKM circular vents are made of galvanized sheet steel, mounting with screws. The tightness of the vents is ensured by sealing around the perimeter. The vents are designed for environments protected against weather influences with the classification of climatic conditions of class 3K5, without condensation, icing, ice formation and without water also from sources other than rain according to EN 60 721-3-3 zm.A2.

On request, it is possible to supply frames of the vents and of the rotating blades with baking varnish according to RAL.

 

NOVA A

NOVA A

The NOVA-A diffusion grilles are HVAC end elements for air distribution in air-conditioned, ventilated and heated rooms. The diffusion grilles are made of anodized aluminium profiles. Lacquered diffusion grilles can be available on request. The NOVA-A diffusion grilles are available in a single row or double row design as well as with the R1 regulation. The diffusion grilles can be installed directly in four-sided ducts, walls or ceilings. The diffusion grille can be installed by means of screws on the front of the grille or of springs. The maximum temperature of the flowing air is 50 °C.

On request, it is possible to supply the HVAC aluminium grilles in any colour according to the RAL colour chart.

 

NOVA B

NOVA B

The NOVA-B diffusion grilles are HVAC end elements for air distribution in air-conditioned, ventilated and heated rooms. The NOVA-B diffusion grilles are available in a single row or double row design as well as with the R1, R2, R3 regulations and a mounting frame. The diffusion grilles can be installed directly in four-sided ducts, wall or ceiling. The diffusion grilles can be installed by means of screws on the front of the grille or of springs. Adjustable front blades are standardly horizontal. The maximum temperature of the flowing air is 50 °C.

The diffusion grilles are made of galvanized steel profiles, lacquered grilles can be available on request. On request, it is possible to supply diffusion grilles made of A-304 stainless steel, which is especially suitable for the food processing industry and of A-316 for more aggressive environments, for example with a chlorine content.

 

NOVA C

NOVA C

The NOVA-C diffusion grilles are HVAC end elements for air distribution in air-conditioned, ventilated and heated rooms designed specifically for installation in circular ducts. The NOVA-C diffusion grilles are available in a single row or double row design as well as with the R1 regulation. The diffusion grilles can only be installed in circular ducts using screws on the front of the grille. Adjustable front blades are standardly vertical. The maximum temperature of the flowing air is 50 °C.

The diffusion grilles are made of galvanized steel profiles, lacquered diffusers can be available on request. On request, it is possible to supply diffusers made of A-304 stainless steel, which is especially suitable for the food processing industry and of A-316 for more aggressive environments, for example with a chlorine content.
