Frameless Exhaust Air Grille

Return Air or Exhaust Air (Ceiling & Wall Installation)

Specifications

Material: Aluminium
Application: Return Air or Exhaust Air (Ceiling & Wall Installation)
Functional Features: • Mud-in Plaster Flange Integration: Engineered with a recessed mounting flange that allows joint compound to overlay the perimeter frame, leaving the outer border completely hidden and flush with the drywall surface. • Fixed Aerofoil Blades: Retains permanently fixed aerofoil-shaped blades to maximize airflow efficiency, reduce resistance, and maintain a consistent 50% free area profile. • Fixed Frame Construction: Built as a non-removable core assembly to ensure structural integrity and surface alignment after architectural plastering.
Design Intent: Engineered to manage return and exhaust air pathways within high-end spaces where visible product borders are restricted. Combines a trimless plaster-in framework with an aerofoil blade geometry to maintain low pressure drops, minimize air turbulence, and eliminate vibration noise. • Ideal for: Continuous exhaust or return air zones such as restrooms, corridors, fire escape routes, or common areas demanding clean architectural lines.
Finish: Powder Coated White, Anodized aluminium, or Custom Colors
Size: Standard or Custom Sizes
Optional Accessory: • Opposed Blade Volume Control (OBV) • Insect Screen • Bird Screen • Square-to-Round Adapter (for Flexible Duct)
Installation Specifications: • Drywall Thickness Compatibility: Designed to integrate with standard 9mm, 12mm, and 15mm ceiling board profiles to ensure a perfectly flush, seamless appearance with the finished drywall layout.
