Draft-Free Fabric Air Distribution

Draft-Free Fabric Air Distribution by EKG M&E Sdn Bhd

In the premium commercial and specialized industrial spaces of Kuala Lumpur and Selangor, traditional metal ducting often creates "hot and cold spots" due to high-velocity air being jetted from fixed grilles. Draft-Free Fabric Air Distribution (also known as Displacement Ventilation or Air Sox) solves this by using the entire surface of the duct to gently discharge air. This creates a uniform, low-velocity "lake" of cool air, eliminating the discomfort of cold drafts on occupants.

EKG M&E Sdn Bhd specializes in the engineering of these high-comfort systems, ensuring they meet MS 1525 standards while providing superior energy efficiency.

The Science of "Silent" Airflow

Traditional HVAC systems rely on "mixing" air at high speeds, which can be noisy and turbulent. Fabric systems utilize Micro-perforation and Permeability to achieve a different result.

1. Surface Dispersion vs. Point Source

• Traditional Metal: Air is forced through a few small grilles at high speed (e.g., 3.0 m/s to 5.0 m/s). This creates a "jet" effect that can feel freezing to someone sitting directly underneath while leaving others in the room too warm.

• EKG Fabric: Air is released over the entire length and circumference of the duct at ultra-low velocities (e.g., 0.1 m/s to 0.5 m/s). Because the discharge area is massive, the air "oozes" out rather than "shooting" out, ensuring a perfectly even temperature throughout the room.

2. Thermal Stratification Control

By gently introducing cool air from the ceiling (or walls), fabric ducts allow for better displacement. The cool air naturally sinks and displaces the rising warm air generated by people and electronics, providing a continuous "fresh" feeling without the sensation of moving air.

Critical Operational & Comfort Benefits

As a specialized M&E contractor, EKG ensures your draft-free installation supports building performance:

• TNB Energy Efficiency (Low Static Pressure):

  Because fabric ducts have no internal baffles or restrictive dampers, they require much less force to move air. This allows your fans to run at lower frequencies via Variable Frequency Drives (VFDs), directly reducing your monthly TNB electricity bill and supporting EECA 2024 compliance.

• Anti-Condensation Performance:

  In Malaysia’s high-humidity climate, "sweating" ducts are a major risk. Our permeable fabrics allow a micro-flow of air through the material itself, keeping the surface temperature above the dew point and eliminating condensation without the need for bulky external insulation.

• Acoustic Excellence:

  By removing high-velocity air "whistling" and mechanical vibration, fabric ducts are naturally silent. This makes them the ideal choice for recording studios, auditoriums, libraries, and open-plan offices.
