Aluminum Multi-Slot Linear Slot Diffuser

The Multi-Slot Linear Slot Diffuser is a high-performance architectural HVAC air distribution system designed for concealed ceiling applications in modern commercial and residential buildings. It provides continuous linear airflow while maintaining a minimalist architectural ceiling appearance.

All units are manufactured on a project-based, made-to-order system according to architectural drawings, ceiling layouts, and HVAC airflow requirements. No standard stock sizes are available, ensuring full flexibility for engineering and design integration.

Engineering Overview

Manufactured from precision extruded aluminum profiles, this linear slot diffuser delivers a continuous, low-visibility air distribution system that integrates seamlessly into modern architectural ceilings.

It is engineered for stable airflow performance, thermal comfort, and acoustic control, making it suitable for demanding HVAC environments.

Fully compatible with:

• VAV (Variable Air Volume) systems
• Constant volume HVAC systems

Problems This Product Solves

• Bulky ceiling diffusers affecting architectural aesthetics
• Uneven air distribution in large interior spaces
• Direct air drafts causing occupant discomfort
• Noise issues in occupied environments
• Limited flexibility in concealed ceiling design systems

Engineering Airflow Performance

This system delivers optimized HVAC performance through:

• Coanda effect airflow for ceiling-adhering air distribution
• Uniform laminar airflow for improved comfort consistency
• Multi-slot configuration (1–6 slots) for scalable performance
• Adjustable air direction control (on-site tuning capability)
• Low-noise aerodynamic design for quiet environments
• Stable operation under VAV and constant volume systems
• Suitable for both supply and return air applications

Material & Construction

• Frame: Extruded aluminum alloy 6063-T5
• Slot profile: Precision CNC-machined for airflow stability
• Surface finish: Electrostatic powder coating (RAL colors available)
• Plenum box: Optional galvanized steel with OBD damper
• End caps: Aluminum or ABS architectural finish
• Structure: Corrosion-resistant for long-term HVAC operation
