Ventilation grilles and diffusers
Purpose of air distribution devices
Air distribution devices - grilles and diffusers - are the final element of supply and exhaust ventilation and air conditioning systems. The correct choice of elements determines the uniformity of temperature distribution, flow velocity, and acoustic comfort in the room.
The company SIA Akvilon offers a wide range of elements for air distribution and extraction. The catalog includes both standard models available from stock and solutions that can be custom-made according to individual dimensions and drawings.
Product range
The catalog includes devices for solving various engineering tasks, divided into three main categories:
External facade grilles
Serve to protect ventilation ducts from atmospheric precipitation, birds, and debris on building facades.
- Galvanized steel: Universal external grilles with the option of powder coating.
- Aluminum (YGAV): Lightweight and corrosion-resistant round grilles.
- Stainless steel (UVLA): External grilles of special round cross-section with a protective hood.
- Gravity (GRM): Plastic models equipped with movable louvers that open under air pressure and close when the system is turned off, preventing backdraft.
Internal ventilation grilles
Designed for indoor installation, air flow distribution, and ventilation duct finishing.
- With fixed louvers: Classic plastic (D/RW) and hygienic stainless steel models (D/TKM) for standard air exchange.
- With mechanical louvers: Plastic grilles (D/15 WR, IMPERIO, D/TK, NKM) for manual adjustment of pressure and flow direction in round and flat ducts.
- Adjustable steel (JR): Single-row (JR 3/2, JR 3/V) and double-row (JR 7/2, JR 7/V) grilles for precise direction of the air jet in one or more planes.
- Specialized solutions: Door transfer grilles (KD) for natural circulation between rooms, internal gravity grilles (KRZ), and models with a built-in non-return valve (Duo Smart).
Ventilation diffusers
Provide air distribution in rooms with ceiling or wall mounting.
- Disc (DVS, DKF): For uniform air supply from the ceiling. Available as classic supply (DVS-P), exhaust (DVS) steel diffusers, and multi-cone models (DKF).
- Flat universal: Galvanized steel models (KNI-RMI).
- Plastic ceiling: Concentric diffuser grilles (KOS).
- Linear slot (LDS ALNOR): Aluminum diffusers with independent slot adjustment for concealed mounting in suspended ceilings.
Specifics of deliveries and solutions
- Comprehensive approach: Supply of finished products from European manufacturers and production of simple elements at our own facilities.
- Custom dimensions: The possibility of ordering grilles according to individual dimensions and project sketches for specific tasks.
- Powder coating: Painting metal products in colors according to the RAL catalog for exact matching with the interior or facade architecture.
- Stock availability: The most popular standard items are always kept in stock for prompt dispatch.
- Project solutions: Special terms of cooperation and flexible pricing for construction projects.
