High-Performance Perforated Diffusers for Quiet, Even Airflow
These 14x4 inch galvanized steel perforated diffusers with aluminum frames deliver superior air distribution without drafts or noise. Perfect for offices, hospitals, and homes, their precision perforations create comfortable environments while blending discreetly into ceilings. The corrosion-resistant build ensures lasting performance in any setting.
HVAC contractors appreciate the reliable airflow control, while architects value the clean, modern profile. Professional installation recommended for peak performance.
- Fits 14x4" Openings: This air register is designed to cover 14x4 inch duct cuts, making it a reliable choice for both new construction and retrofit projects. Please see submittal drawing for detailed measurements.
- Enhanced Air Diffusion: The perforated steel face panel disperses air gently, promoting better air mixing and reducing drafts for more consistent room comfort.
- Eliminates Ceiling Stains: A built-in foam gasket compresses against the ceiling to create an airtight seal, preventing dusty air leaks that lead to unsightly dark rings around the vent.
- Rugged Aluminum and Steel Build: Constructed with a solid extruded 6063-T5 architectural aluminum frame and a galvanized steel panel for exceptional durability and long-term performance in commercial environments.
- Clean, Customizable Installation: No pre-drilled holes gives installers the flexibility to fasten the AC vent cover based on their specific job-site requirements for a perfect, seamless fit.
- Optional Airflow Control: An add-on damper is available (sold separately) to provide manual control over air volume, helping to balance the system for optimal performance.
- Durable Matte White Finish: The matte white powder coat is resistant to corrosion and fading, ensuring the diffuser maintains its like-new appearance for years.
- Professional-Grade Hardware Flexibility: This perforated air grille is supplied without fasteners, allowing HVAC technicians to choose their preferred screws for the specific wall or ceiling material.
- Tailored Plenum Solutions: For a perfectly integrated HVAC system, we offer custom plenum boxes (sold separately) designed to your specifications. This optional add-on enhances air delivery efficiency and ensures seamless compatibility with your ductwork.
