In the industrial and commercial sectors of Kuala Lumpur and Selangor, Axial Flow Ventilation Fans are the workhorses of large-scale air movement. Unlike centrifugal fans that turn air at a 90-degree angle, axial fans move air parallel to the shaft, similar to an airplane propeller. EKG M&E Sdn Bhd specializes in the selection, installation, and maintenance of high-static axial fans for everything from general warehouse cooling to critical life-safety systems.
Axial fans are chosen when a project requires moving high volumes of air (high CMH/CFM) at relatively low to medium pressures.
High Volumetric Efficiency: These fans are ideal for "thoroughfare" ventilation, where the goal is to flush a large space like a factory or basement car park quickly.
Compact Inline Design: Because the air enters and leaves in a straight line, axial fans can be installed directly "inline" with the ductwork, saving significant mechanical room space compared to bulky centrifugal units.
Adjustable Pitch Blades: Many of our high-end axial units feature manually adjustable blade pitches. This allows our M&E team to fine-tune the airflow on-site during the Testing and Commissioning (T&C) phase to match the building's actual resistance.
As an HVAC and Clean Air Specialist, we deploy axial technology in three primary configurations:
In the event of a fire, these fans become the building's "lungs."
Class H Certification: We install axial fans rated to operate at 250°C for 2 hours.
BOMBA Compliance: We ensure these fans are interlocked with the Main Fire Alarm Panel to provide the mandatory 10 Air Changes Per Hour (ACH).
To manage Carbon Monoxide (CO) levels in KL’s deep basement parking lots, we utilize dual-speed axial fans.
Low Speed: Daily energy-efficient CO purging.
High Speed: Emergency smoke extraction mode triggered by the fire system.
VFD Integration: We utilize Variable Frequency Drives (VFDs) to ramp fan speeds based on real-time CO sensor data, drastically reducing TNB electricity costs.
We use axial fans to "push" fresh air into stairwells to create a 50 Pa pressure shield.
Stairwell Pressurization: Ensuring escape routes remain smoke-free by maintaining a positive pressure gradient.
| Feature | Axial Flow Fan | Centrifugal Fan |
| Airflow Direction | Straight through (Inline). | 90-degree turn. |
| Air Volume | Very High. | Medium. |
| Static Pressure | Low to Medium. | Very High. |
| Installation | Space-saving (Duct-mounted). | Requires floor/base space. |
| Primary Use | Smoke Spill / General Vent. | AHU Supply / Long Duct Runs. |
Airflow Balancing and Commissioning: We don't just "bolt on a fan." We perform a full Duct Traverse and Static Pressure Audit to ensure the fan is operating on its peak performance curve, preventing motor overheating and excessive noise.
Acoustic Treatment: High-velocity axial fans can be noisy. We design and install customized Cylindrical Silencers (Attenuators) to ensure your ventilation system meets local noise ordinance levels in residential or quiet office zones.
Klang Valley Strategic Support: Based in Kuala Lumpur, we provide on-site vibration analysis, bearing replacements, and annual safety certifications for industrial axial systems across the Klang Valley.
