Dust collection manifold duct fabrication

Dust Collection Manifold Duct Fabrication by EKG M&E Sdn Bhd

In the industrial manufacturing hubs of Selangor and Kuala Lumpur, a dust collection system is only as effective as its distribution network. EKG M&E Sdn Bhd provides specialized Dust Collection Manifold Duct Fabrication, engineered to manage the heavy particulate loads and high static pressures required for effective source capture. Unlike standard HVAC ducting, a dust collection manifold must maintain a constant "Transport Velocity" to prevent dust from settling, which reduces fire risks and prevents system clogs.

Engineering Selection by Application

We design and fabricate manifolds based on the specific "Cubic Feet per Minute" (CFM) and the density of the particulate matter in your facility.

1. Multi-Point Source Capture (Zonal Efficiency)

For facilities with multiple machines (e.g., woodworking, CNC milling, or metal grinding), the manifold acts as the central hub.

• Tapered Main Trunk Design: We fabricate manifolds with a tapered design that increases in diameter as each branch joins. This ensures that the air velocity (typically 3500 to 4500 FPM) remains constant throughout the entire system, preventing "dead zones" where dust can drop out of suspension.

• 30-Degree Lateral Entries: To minimize turbulence and static pressure loss, our manifolds utilize 30-degree lateral entries (Y-branches) rather than 90-degree tees. This smooth transition allows the air streams to merge aerodynamically, reducing the load on your primary suction fan.

2. Heavy-Duty Industrial Processing (Abrasive Resistance)

For industries handling abrasive materials like cement, metal shavings, or silica, standard ducting will wear through quickly.

• Heavy-Gauge GI and Carbon Steel: We fabricate dust manifolds using 14-gauge to 18-gauge galvanized or carbon steel. This extra thickness provides the "wear allowance" necessary to withstand years of internal abrasion from high-speed particles.

• Reinforced Long-Radius Elbows: Where the manifold changes direction, we utilize long-radius elbows (centerline radius of 1.5x to 2x diameter). These are often fabricated with reinforced "wear plates" at the outer radius where the impact of the dust is most severe.

3. Combustible Dust Management (Safety Compliance)

For facilities handling wood dust, flour, or sugar, the manifold must be engineered to prevent static buildup.

• Grounded All-Metal Construction: We utilize fully conductive sheet metal construction with integrated grounding lugs at every joint. This ensures that static electricity—generated by the friction of dust moving through the duct—is safely discharged, preventing explosive sparks.

• Clean-Out Access Ports: Our manifolds feature strategically placed, airtight access doors. This allows your maintenance team to inspect the interior and manually remove any heavy buildup during scheduled shutdowns.

Critical Fabrication and Installation

As an industrial M&E specialist, EKG ensures the manifold is a precision-balanced mechanical component:

Airtight Longitudinal Seams:

Dust manifolds operate under significant negative pressure. We utilize Fully Welded or Pittsburgh Lock seams, followed by high-pressure industrial sealants. This ensures an airtight seal that prevents "air-bleeding," which would otherwise drop the suction velocity at your machines.

Precision Balancing and Dampers:

To ensure each machine receives the correct CFM, we integrate manual or automated Blast Gates (slide dampers) into the manifold branches. Our engineers perform a full Air Balance Audit, adjusting the gates until the capture velocity at every workstation meets DOSH (JKKP) safety requirements.

Modular Flange Systems:

For large-scale factory installations, we utilize Quick-Fit (QF) or TDF Flange systems. This modular approach allows for faster on-site assembly and makes it easier to modify the manifold if you add or move machinery in the future.
