Air diffusers are ventilation components designed to supply air to rooms and extract air from them. They are used in mechanical ventilation and heat recovery systems in houses, apartments, offices and commercial premises. At el-vent.com, you can choose from five categories: plastic, metal, plaster-in, acoustic and linear slot air diffusers. The range includes AIR, AN-ABS, PP-PVC, Classic DP and DI, Silent DPN, DPNN, DIN and DINN, INOX DNU, SQUARE-A, FRAMELESS and PLD series. Diffusers differ in material, shape, mounting method, airflow adjustment and acoustic performance. The right model is selected according to duct dimensions, design airflow and room requirements.

Air diffusers for ventilation are terminal components installed at supply and extract points in a duct system. Supply air diffusers distribute incoming air within a room, while extract air diffusers collect air to be removed. Some models are universal and suitable for both airflow directions.
The choice of diffuser affects airflow distribution, pressure loss, ventilation noise and interior appearance. In addition to shape and price, consider technical performance, connection dimensions and installation conditions.
Plastic air diffusers are lightweight, easy-to-maintain air distribution components used in residential and other ventilation systems. The category includes AIR, AN-ABS and PP-PVC series.
AIR diffusers feature push-in fixing tabs, while AN-ABS and PP-PVC offer different construction and mounting solutions. Choose according to connection diameter, installation location and the specified application of the model.
Metal air diffusers are made from galvanised steel, stainless steel or aluminium. This category includes conventional round diffusers, square ceiling diffusers and linear models.
Classic DP is designed for supply air and Classic DI for extract air. Both have adjustable dampers and a white RAL9003 finish. INOX DNU diffusers are made from AISI304 stainless steel and are suitable for supply and extraction. SQUARE-A is a series of square aluminium ceiling diffusers.
Choose a metal diffuser according to its application, material resistance, required airflow, installation dimensions and interior design.
FRAMELESS plaster-in gypsum diffusers are designed for plasterboard ceilings. Their bodies are integrated into the ceiling finish, filled and painted to match the surrounding surface. After installation, only a narrow airflow slot remains visible.
The range includes round FRAMELESS RONDO and square FRAMELESS KVADRO diffusers with removable magnetically secured central covers. They are suitable for minimalist interiors where visible ventilation components should be discreet.
Silent acoustic air diffusers are specially designed to help reduce noise generated by air passing through the diffuser. They are particularly relevant to bedrooms, offices and other noise-sensitive spaces.
Silent DPN is universal for supply and extraction. Silent DPNN is designed for supply air and includes directional adjustment. Silent DIN and DINN are intended for extraction. DPNN and DINN have gasketed connection spigots.
Select an acoustic diffuser according to design airflow, pressure loss and the manufacturer's noise performance data.
Linear slot air diffusers distribute air through one or more narrow elongated openings. They are used where linear air distribution and a modern ceiling appearance are desired.
The aluminium PLD series includes one-, two-, three- and four-slot models. They are suitable for supply and extraction and for distributing warm or cold air. Each slot has an individual airflow adjustment damper. Compatible PLDD plenum boxes may be used to connect the diffusers to ductwork.
First establish whether the diffuser will supply or extract air. Not all models are universal: Classic DP is intended for supply, Classic DI for extraction, while Silent DPN is suitable for both. Follow the manufacturer's specified application.
The connection diameter of a round diffuser must match the duct or suitable fitting. For square and linear diffusers, external dimensions, installation openings and the plenum box arrangement must also be considered.
The diffuser should be selected according to the design airflow in m³/h. An undersized opening or heavily restricted damper may increase velocity, pressure loss and aerodynamic noise. Check the specific model's technical characteristics.
For noise-sensitive rooms, consider the Silent acoustic series. Actual noise, however, also depends on the fan, ductwork, airflow volume and system balancing.
Conventional plastic and metal diffusers are suitable for a range of standard installations. FRAMELESS is designed for plasterboard ceilings requiring a flush plastered finish. PLD provides linear air distribution, while SQUARE-A offers square ceiling diffuser solutions.
Air diffusers are widely used in heat recovery systems that supply fresh air to living areas and remove used air. Depending on the design, they may be installed in living rooms, bedrooms, home offices, kitchens, bathrooms and utility spaces.
The diffuser application, airflow and pressure loss must be coordinated with the entire duct system. Appearance and connection diameter alone do not establish suitability for a particular installation.
Installation depends on the product construction. Diffusers can be fitted to round ducts, mounting connections or plenum boxes. FRAMELESS plaster-in models are installed during the construction and finishing of plasterboard ceilings.
Diffusers should be cleaned periodically to remove dust and dirt. Use cleaning products suitable for the material and finish. If a diffuser has an adjustable damper, retain the commissioned airflow setting after cleaning.
Supply air diffusers distribute incoming air, while extract diffusers collect air to be removed. Some series have a dedicated application, while others can perform both functions.
Different types may be used if their application, connection dimensions, airflow and pressure loss are compatible with the ventilation design.
Conventional, acoustic or plaster-in models may all be suitable. The important factors are noise performance, airflow distribution and compatibility with the planned ventilation rate.
No. Adjustment depends on the series. Classic and Silent models have adjustable components, while other types may require separate dampers elsewhere in the ventilation system.
Plastic models are lightweight and do not require protective metal coatings against corrosion. Metal diffusers may be made from galvanised steel, stainless steel or aluminium. Choose according to environmental and technical requirements.
The FRAMELESS body blends into the ceiling finish, but the round or square airflow slot remains visible.
Yes. The PLD series is suitable for both supply and extraction.
No. Noise depends on the design, airflow, damper setting and pressure loss. Manufacturer acoustic data should be used for evaluation.
