In the industrial environments of Kuala Lumpur and Selangor, a central vacuum system is a critical utility for heavy-duty cleaning, material recovery, and hazardous dust containment. Unlike standard ventilation, Vacuum System Ducting operates under constant high-negative pressure. This requires a specialized "implosion-proof" design and a "snag-free" internal architecture to prevent the clogs that typically plague lower-quality installations.
EKG M&E Sdn Bhd specializes in the engineering of high-vacuum networks, ensuring your facility complies with DOSH safety standards and the EECA 2024 energy mandates.
Vacuum ducting must be significantly more robust than standard air-handling vents to prevent structural failure under intense suction.
While positive pressure tends to round out a duct, negative pressure tries to collapse it.
Heavy-Wall Piping: We utilize thick-walled Zinc-Plated Steel or Industrial PVC specifically rated for high vacuum levels ($P_{static}$).
Structural Integrity: For large-diameter headers, we incorporate external reinforcement rings to provide the necessary "hoop strength" to resist atmospheric pressure.
Particulates in a vacuum system move at high velocities. Even a minor internal ridge can cause a major blockage.
Specialized Couplings: We avoid standard slip-fit joints. Instead, we use tapered vacuum couplings or Clamp-Together systems that ensure pipe ends butt together perfectly. This creates a "glass-smooth" interior.
No Internal Fasteners: Screws and rivets are strictly avoided, as they act as "hooks" for stringy fibers and moist dust.
As a specialized M&E contractor, EKG ensures your vacuum network supports both plant hygiene and the bottom line:
TNB Energy Efficiency (VFD Calibration):
Vacuum pumps are high-energy consumers. By eliminating "fugitive air" leaks through hermetic sealing and utilizing Variable Frequency Drives (VFDs), we ensure the pump only pulls the air required for active inlets. This can reduce your monthly TNB electricity bill by up to 50%.
Flow-Optimized Geometry:
We follow strict fluid dynamic protocols, utilizing Long-Radius Sweeps and 45° Lateral Entries. This maintains the "Minimum Transport Velocity" (typically 20–30 m/s), ensuring material reaches the separator without settling in horizontal runs.
Static Electricity Dissipation:
Moving dry particulates creates massive static charges. We ensure the entire network is electrically bonded and grounded, preventing sparks that could trigger a dust explosion—a critical requirement for ATEX-compliant facilities.

Total 3D BIM Coordination: We model every vacuum run in 3D to ensure "clash-free" installation around existing electrical trays, steam lines, and structural beams, prioritizing the straightest possible runs for maximum efficiency.
Turnkey Validation: We provide full Testing & Commissioning (T&C), including pressure leakage testing and inlet velocity audits required for safety and environmental compliance.
Regional Industrial Support: Based in Kuala Lumpur, we provide site audits and professional installations for semiconductor labs, food processing plants, and high-precision machine shops across the Klang Valley.
