In the semiconductor, pharmaceutical, and high-tech manufacturing corridors of Selangor, maintaining the integrity of a Grade-A Cleanroom is a zero-tolerance mechanical requirement. EKG M&E Sdn Bhd provides Cleanroom Grade-A Process Exhaust systems, specifically engineered to remove hazardous gases, chemical vapors, and particulates without compromising the sterile environment. We focus on absolute containment, zero fiber-shedding, and "No-Bypass" sealing to ensure your facility meets ISO 14644-1 standards.
Cleanroom environments require more than just corrosion resistance; they require materials that will not out-gas or release particles into the ultra-pure air stream. Our Grade-A systems utilize high-purity materials and specialized jointing technology to protect both your personnel and your yield.
We specify the ducting substrate and internal finish based on the ISO class of your cleanroom and the chemical sensitivity of your production tools.
1. Semiconductor Fabrication and Photolithography
Processes involving volatile organic compounds (VOCs) and etching acids require inert air transport.
FM-Approved Fluoropolymer Coated Stainless Steel: For high-risk fire zones, we utilize Grade 316 stainless steel with an internal fluoropolymer (Teflon-based) coating. This provides absolute chemical resistance while meeting Factory Mutual (FM) standards for non-combustibility.
Hermetic Tri-Clamp Connections: We utilize sanitary-grade Tri-Clamp or specialized flange joints with high-purity PTFE gaskets to ensure the exhaust path is 100% airtight and "Bubble-Tight" under pressure.
2. Pharmaceutical and Biotech Formulation (Sterile Extraction)
In zones where drugs or vaccines are processed, the exhaust system must be "Hygienic Grade."
High-Purity Electropolished Stainless Steel: We utilize 20Ra or 15Ra electropolished internal finishes. This ultra-smooth surface prevents microscopic particulates or bacteria from adhering to the duct walls, ensuring no "cross-batch" contamination occurs via back-flow.
Orbital Welded Joints: To eliminate the crevices found in standard welding, our technicians use orbital welding. This creates a smooth, seamless internal bead that meets the most stringent pharmaceutical cGMP requirements.
3. Tool-Specific Point-of-Use Extraction
The connection between the production tool and the main header is the most critical point of the system.
Zero-Outgassing Material Selection: We ensure that all flexible connectors and sealants are certified "Zero-Outgassing," preventing the release of silicones or plasticizers that can ruin sensitive silicon wafers or optics.
VFD-Interlocked Scavenging Flow: We integrate our ducting with precision sensors and Variable Frequency Drives (VFDs) to maintain a constant scavenging velocity at the tool interface, ensuring fumes are captured instantly as they are generated.
As a specialist M&E contractor, EKG ensures the exhaust system operates as a "Closed-Loop" safety infrastructure:
Negative Pressure Differential Management:
We engineer the system to maintain a strictly controlled Negative Pressure relative to the cleanroom. This ensures that in the event of a mechanical seal failure, air only moves from the cleanroom into the exhaust duct, never the reverse, protecting the sterile zone from chemical infiltration.
HEPA/ULPA Filter Integration:
For hazardous process exhaust, we install "Bag-In / Bag-Out" (BIBO) filter housings equipped with HEPA or ULPA filters. This allows for the safe replacement of contaminated filters without exposing the cleanroom or the environment to dangerous particulates.
Vibration Decoupling and Inertia Bases:
Exhaust fans generate mechanical resonance. We install high-efficiency vibration isolators and utilize flexible, chemical-resistant connectors to ensure that fan vibration is not transmitted back to the sensitive production tools through the rigid ductwork.

Yield-Driven Engineering: We understand that a single particle or chemical trace can cause millions in lost production. Our designs focus on protecting your product as much as your people.
Total System Certification: We provide the documentation, pressure test logs, and weld certifications required for cleanroom validation and ISO audits.
Strategic Selangor Support: Based in Kuala Lumpur, we provide site audits for existing cleanrooms, tool-hookup retrofits, and professional installation for Malaysia’s high-tech manufacturing sector.
