Interior Grilles
Effective ventilation systems require high performing and aesthetically appealing internal grilles and diffusers. Vent Supply provides a wide range of products for multiple applications.
Cone Diffusers
Constructed from durable white ABS plastic with an etched finish to minimize light reflectivity, cone diffusers blend seamlessly into any ceiling. The diffuser’s design ensures that airflow hugs the outer body and disperses in a concentric pattern along the ceiling for optimal air distribution and comfort.
Swirl Diffusers
Designed for high-efficiency air distribution in commercial and industrial spaces, swirl diffusers deliver excellent mixing and rapid temperature equalisation. The unique swirl pattern promotes a high level of induction, making them ideal for both cooling and heating applications with variable air volumes.
Constructed from durable steel and finished in a clean white powder coat, they’re available in multiple neck sizes and mounting options, including exposed ceiling and flush-mount configurations. Swirl diffusers provide uniform airflow and minimal drafts, making them a preferred choice for offices, lobbies, and other large open areas.
Door Grilles
Designed for ease of installation, our door grilles includes an adjustable telescopic backframe with spring clips that seamlessly secure to the rear of the door insert, ensuring a flush appearance. Suitable for door thicknesses from 30mm to 45mm. Available in multiple stock sizes or customisable to any size upon request, it comes standard in Natural Anodised aluminium but can be powder-coated to any specified colour.
Aluminium Eggcrate Grilles
Removable core eggcrate grilles are a reliable and versatile option for return and exhaust air applications in both commercial and residential settings. Made from high-quality extruded aluminium and customisable up to 1000 x 1000mm, it offers excellent durability and performance.
The grille features a 13mm x 13mm x 13mm channeled cube core with approximately 90% free area, allowing for high airflow with minimal noise or pressure drop. The removable core clips easily into the 25mm outer frame, making installation, cleaning, and maintenance simple.
