Square Diffuser installed in commercial ceiling – uniform air distribution

Product Overview

What Is a Square Ceiling Diffuser?

A square ceiling diffuser is a precision HVAC component mounted in ceiling grids to distribute conditioned air uniformly across a room. Its square geometry and multi-directional deflection blades eliminate temperature hot spots, ensuring consistent comfort at every corner of the space.

Designed to integrate seamlessly with standard modular ceiling systems, our square diffusers combine aerodynamic efficiency with a clean architectural profile — ideal for contemporary commercial and institutional interiors.

Frame Material Extruded Aluminium

Sheet Thickness 1.2 mm

Blade Pitch 20 mm

Standard Finish RAL 9016 Powder Coat

Damper Collar (Matt Black)

Why Airotek

Why Choose Our Square Diffuser Manufacturing?

From raw material selection to final quality testing, every square diffuser we produce meets the highest engineering and performance standards.

🏭

Superior Manufacturing Standards

Our fabrication process uses premium-grade extruded aluminium, galvanised steel, and corrosion-resistant alloys. Advanced CNC tooling ensures precise blade angles, smooth surface finishes, and tight dimensional tolerances.

📐

Comprehensive Size Range

Available in standard sizes compatible with modular T-bar ceilings, plus custom dimensions for non-standard ductwork and specialised architectural applications. Multiple neck sizes for flexible system integration.

🌬️

High-Performance Airflow

20 mm blade spacing maximises the effective free area, minimising outlet velocity and pressure drop. The result: whisper-quiet operation and excellent throw distance for uniform climate control in large spaces.

⚙️

Integral Opposed-Blade Dampers

Models AG-V-D and AG-H-D feature single-deflection blades with integral opposed-blade dampers, adjustable via a screwdriver slot operator for precise airflow balancing at the outlet level.

🎨

Custom Finishes on Request

Standard RAL 9016 white powder coat suits most commercial interiors. We also supply anodised, custom RAL colour, and special architectural finishes to match any interior design specification.

✅

Rigorous Quality Assurance

Every unit undergoes dimensional inspection, finish verification, and performance testing before dispatch. Our technical team provides CFD analysis support and installation guidance for optimal system results.
