Airfoil’s Fixed Core Half Chevron Grille (3AR), proudly Australian Made and designed, is meticulously crafted from premium aluminium extrusion profiles. Tailored to any size, this grille features distinctive fixed slimline 45-degree blades, spaced at 19mm intervals, providing a total free area of approximately 70%. Ideal for wall return or transfer applications, the 3AR achieves a no-sight effect below or above eye level by simply inverting the grille. The slimline half-chevron blades are securely housed within its 40mm deep frame. Supported by mullions, spring-loaded steel wires, and knock-on star washers, the fixed blades ensure strength and rigidity.
Featuring a sleek and aesthetically pleasing 32mm frame, the 3AR grille is available with an optional Opposed Blade Damper (OBD) for air balancing and commissioning purposes. Additionally, it can be fitted with insect vermin mesh at the rear for pest control. Available in our standard white range, the 3AR also comes in our Natural Anodised silver finish or can be custom powder-coated to any desired colour upon request. Rigorously tested to meet Australian standards, Airfoil’s Fixed Core Half Chevron Grille (3AR) is well-suited for various commercial return or exhaust air transfer applications.
