Plastic air diffusers for ventilation are components designed to supply air to rooms and extract air from them. They are used in houses, apartments, offices and other premises equipped with mechanical ventilation or heat recovery systems. Plastic diffusers are lightweight, do not rust, are easy to clean and require little maintenance. The el-vent.com range includes three series: AIR, AN-ABS and PP-PVC, designed for different duct diameters and installation methods. Available sizes range from Ø75 to Ø200 mm. The appropriate diffuser should be selected according to the duct diameter, required airflow and installation conditions.

Plastic air diffusers are ventilation system components installed at the ends of air ducts to supply air to rooms or extract it from them. They are used in mechanical ventilation and heat recovery systems in houses, apartments, offices and other premises.
Plastic diffusers are lightweight, do not rust, are easy to clean and require little maintenance. They complement various interior designs and, thanks to their compact construction, are frequently installed in ventilation openings in ceilings and walls.
The el-vent.com range includes three different plastic air diffuser series – AIR, AN-ABS and PP-PVC. The choice depends on the duct diameter, installation method and purpose of the ventilation system.
AIR – round plastic air diffusers designed for ceiling installation and connection to round ventilation ducts.
This series features special push-in mounting tabs that secure the diffuser in the installation opening. The white decorative front, with its smooth central disc and annular airflow opening, gives the diffuser a minimalist appearance.
Available AIR diameters: Ø75, Ø100 and Ø125 mm.
These diffusers can be used in ventilation systems in residential and commercial premises where a neat ceiling finish and compact construction are important.
AN-ABS – universal air diffusers made of ABS plastic. They are designed for both air supply and air extraction systems.
The diffusers are supplied with mounting screws, so their installation method differs from the AIR series with push-in mounting tabs.
Available AN-ABS diameters: Ø100 and Ø125 mm.
AN-ABS diffusers are a practical choice when a simple plastic air diffuser is required for a conventional mechanical ventilation system.
PP-PVC – universal air diffusers made of PVC plastic, designed for both air supply and extraction.
This series features larger connection diameters, making it suitable for ventilation systems using larger round air ducts.
Available PP-PVC diameters: Ø160 and Ø200 mm.
PP-PVC diffusers complement the smaller AIR and AN-ABS models, offering plastic diffuser options for ventilation systems with different duct diameters.
When choosing a plastic diffuser, it is important to consider not only its appearance but also its technical compatibility with the ventilation system.
The diffuser connection dimensions must match those of the duct or installation connector. The AIR series is available in Ø75, Ø100 and Ø125 mm, AN-ABS in Ø100 and Ø125 mm, and PP-PVC in Ø160 and Ø200 mm.
Before ordering, it is advisable to check not only the nominal duct diameter but also the diffuser's technical drawing and actual connection dimensions.
AN-ABS and PP-PVC are universal diffusers used in both supply and extract ventilation systems. The suitability of the AIR series for a particular airflow direction should be assessed according to its technical specifications.
A supply air diffuser must provide suitable air distribution within the room, while an extract air diffuser must remove the required volume of air.
Different series use different fixing solutions. AIR diffusers have push-in mounting tabs, while AN-ABS diffusers are supplied with mounting screws. The installation opening and its construction should be considered when selecting a diffuser.
The installation method must ensure secure fixing while allowing the diffuser to be removed or accessed for cleaning if the product design permits it.
The diffuser diameter alone is insufficient to determine its airflow capacity. The design airflow (m³/h), pressure loss and noise characteristics should also be considered if these data are provided in the manufacturer's technical documentation.
Excessive air velocity through the diffuser opening can increase aerodynamic noise and cause uncomfortable draughts. Therefore, the diffuser should be selected according to the design parameters of the ventilation system.
Plastic diffusers are easy to clean when dust accumulates. Regular maintenance helps keep the airflow opening clean and maintain the diffuser's appearance.
Cleaning should be carried out with a soft cloth and cleaning products suitable for plastic surfaces, following the manufacturer's instructions.
Both types of diffusers are used in ventilation systems, but the choice depends on environmental conditions, construction and project requirements.
Plastic air diffusers are lightweight, do not rust and are easy to maintain. These characteristics make them a practical choice for residential ventilation, including bathrooms, kitchens and utility rooms.
Metal air diffusers are more commonly chosen when greater mechanical strength or specific technical properties are required.
In both cases, the most important consideration is that the selected diffuser matches the ventilation system's airflow, installation conditions and room function.
Plastic diffusers can be used in various premises equipped with mechanical ventilation or heat recovery systems:
A plastic air diffuser is a ventilation system component installed at the end of an air duct to supply air to a room or extract it. Its construction and intended application depend on the diffuser series.
Yes. Plastic diffusers can be used in heat recovery ventilation systems if their connection dimensions and airflow characteristics match the system design.
The main differences are their construction, material, installation method and available diameters. AIR diffusers have push-in mounting tabs and are available in Ø75–Ø125 mm sizes. AN-ABS diffusers are made of ABS plastic, supplied with mounting screws and available in Ø100–Ø125 mm sizes. PP-PVC diffusers are made of PVC plastic and are available for Ø160 and Ø200 mm ducts.
AN-ABS and PP-PVC are universal series suitable for both airflow directions. The applications of AIR diffusers depend on the technical specifications of the particular model.
Yes, provided a model suitable for ceiling installation is selected. The AIR series is intended for ceilings, while the installation conditions of other models should be checked in their technical documentation.
First, determine the diameter of the air duct or connection fitting. The planned airflow, pressure loss and diffuser performance characteristics should also be considered to ensure proper ventilation system operation.
Plastic does not rust, so plastic diffusers can be used in bathrooms and other humid rooms. However, the suitability of the specific material and product for the operating conditions should be checked.
Wall installation depends on the diffuser's construction and the manufacturer's mounting instructions. Some series are designed for ceiling installation, so their intended application must be checked before wall mounting.
Airflow adjustment depends on the diffuser's construction. Not all plastic diffusers have an integrated adjustment mechanism. If the product has no such mechanism, airflow is regulated using other components of the ventilation system.
Aerodynamic noise depends on airflow volume, air velocity, diffuser construction and pressure loss. A correctly selected diffuser helps reduce unwanted airflow noise.
Yes. Plastic diffuser surfaces can be cleaned periodically to remove dust and other deposits using products suitable for the particular material.
