In the precision manufacturing hubs of Shah Alam, Puchong, and the wider Klang Valley, CNC machining centers generate a constant volume of oil mist and coolant vapors. EKG M&E Sdn Bhd provides specialized Oil-Mist Extraction Ducting, specifically engineered to capture these aerosols at the source. Our systems prevent the formation of "oil rain" on factory floors, protect sensitive machine electronics from moisture, and ensure a healthy breathing environment for your operators in accordance with DOSH (JKKP) safety standards.
Standard HVAC ducting will leak and degrade when exposed to cutting fluids. We utilize specialized materials and sealing techniques to ensure long-term containment.
1. Oil-Tight Material Selection
Grade 304 Stainless Steel: The premier choice for CNC environments. It is naturally resistant to the chemical additives found in modern synthetic and semi-synthetic coolants, preventing the internal pitting and external rusting common in galvanized systems.
Heavy-Gauge Galvanized Iron (GI): For less aggressive applications, we utilize heavy-gauge GI (18-ga to 20-ga) with oil-resistant internal coatings to provide a cost-effective yet durable extraction path.
2. Leak-Proof Joint Technology
Traditional mechanical seams are the primary failure point in oil-mist systems. We utilize two specialized jointing methods:
Fully Welded Seams: We utilize continuous TIG welding for all longitudinal and girth seams. This creates a monolithic, hermetically sealed pipe that is physically incapable of leaking liquid coolant.
Modular "Pull-Ring" Clamping: For systems requiring frequent cleaning, we use modular ducting with oil-resistant EPDM or Nitrile gaskets. These allow for rapid disassembly without specialized tools while maintaining a liquid-tight seal.
3. Aerodynamic "Drain-Back" Design
Pitch and Slope Integration: We engineer our horizontal duct runs with a slight pitch (typically 1:50) back toward the CNC machine or a central collection sump. This allows condensed oil to flow back for recycling rather than pooling in the ducting.
High-Velocity Scavenging: We maintain a transport velocity of 2,500 to 3,500 FPM to ensure that mist stays in suspension until it reaches the primary mist eliminator.
As an industrial M&E specialist, EKG ensures your CNC extraction is a precision-integrated safety component:
Coalescing Mist Eliminator Integration:
We integrate our ducting with multi-stage mist collectors. These units use high-efficiency coalescing filters to turn airborne droplets back into liquid oil, which can then be piped back into your machine's coolant tank, providing a direct return on investment through material recovery.
Point-of-Use Machine Hook-ups:
We design custom "Drop-Down" connections for individual CNC centers. These include vibration isolation connectors to ensure that the mechanical resonance of the extraction fan does not affect the precision tolerances of your machining work.
Demand-Controlled Extraction (VFD):
To reduce TNB electricity costs, we interlock your extraction system with a Variable Frequency Drive (VFD). The system can be programmed to ramp down when a machine is idle and ramp up the moment the spindle starts and coolant begins to spray.
| Feature | Standard Ventilation Ducting | EKG Oil-Mist Grade |
| Seam Integrity | Slip-fit (Leaks oil) | Fully Welded / Gasketed Clamped |
| Material | Light GI (Corrodes) | SS304 / Heavy GI with Oil-Coating |
| Condensate Management | None (Pools in duct) | Engineered Pitch & Drainage |
| Maintenance | Difficult to clean | Quick-Release Access / Modular |
| Safety Compliance | Poor | DOSH & Environmental Ready |
Coolant Compatibility Analysis: We analyze the type of cutting fluid you use (neat oil vs. water-soluble) to ensure the gaskets and sealants in your ducting will not degrade over time.
Total System Balancing: We perform a full Static Pressure Audit to ensure your mist collector provides the exact "Capture Velocity" required at the machine enclosure to prevent vapor escape.
Strategic Selangor Support: Based in Kuala Lumpur, we provide professional site audits for "leaky" or "smoky" CNC shops, offering expert retrofits and installation for Malaysia's high-precision engineering sector.
