In the automotive and industrial sectors of Kuala Lumpur and Selangor, a paint booth is only as effective as its ventilation system. The exhaust fan is the "engine" of the booth, responsible for pulling hazardous solvent vapors and paint overspray out of the workspace. If the fan is underpowered or incorrectly specified, it leads to "fogging" (poor visibility), finish defects like "orange peel," and—most dangerously—the accumulation of flammable vapors that can lead to fire or explosion.
EKG M&E Sdn Bhd specializes in the engineering, installation, and JKKP (DOSH) LEV Certification of high-performance paint booth fans, ensuring a safe environment and a flawless finish.
As an HVAC and Clean Air Specialist, we select fan types based on the booth’s airflow design (Crossdraft, Downdraft, or Side-Draft) and the specific "Static Pressure" required to pull air through filtration banks.
These are the industry standard for most automotive spray booths. They move high volumes of air parallel to the fan shaft.
The Benefit: Lower initial cost and simple "in-line" duct installation.
The EKG Touch: We use Belt-Drive Tube Axial Fans where the motor is mounted outside the duct. This protects the motor from "paint loading" and flammable vapors, extending equipment life.
For industrial booths with heavy multi-stage filtration or long duct runs, axial fans often "stall." We integrate Backward-Inclined Centrifugal Fans.
The Benefit: They can handle much higher static pressure. As filters get dirty, a centrifugal fan maintains a more consistent airflow than an axial fan.
The EKG Touch: We specify non-overloading wheel designs that protect the motor even if the exhaust filters are removed or the ducting is modified.
Because paint thinners and solvents have low flash points, the fan must be an "Explosion-Proof" assembly. We provide ATEX-certified solutions that meet NFPA 33 standards:
Non-Sparking Construction: We use aluminum or specialized plastic fan blades. If a blade ever makes contact with the housing (due to Vibration), it will not create a mechanical spark.
Explosion-Proof (Ex d) Motors: Our motors are totally enclosed and designed to contain any internal electrical spark, preventing it from igniting the solvent-rich exhaust stream.
Grounding & Bonding: We ensure the entire fan and ducting assembly is electrically bonded to the ground to prevent static electricity buildup from the moving air and paint particulates.
| Feature | Axial Fans (Standard) | Centrifugal Fans (Heavy Duty) |
| Airflow Volume | High (Great for large booths). | Medium to High. |
| Pressure Handling | Low (Airflow drops as filters clog). | High (Maintains airflow longer). |
| Noise Level | High (Often requires silencers). | Quiet (Lower RPM operation). |
| Maintenance | Frequent (Check belt tension). | Low (Enclosed drive system). |
A modern paint booth fan must be "smart" to comply with JKKP (DOSH) requirements:
VFD Airflow Control: We integrate Variable Frequency Drives (VFDs) to allow the painter to switch between "Spray Mode" (High Speed) and "Bake/Cure Mode" (Low Speed), saving up to 40% in electricity.
Safety Interlocks: We install airflow proving switches. If the exhaust fan fails or the VFD trips, the system automatically shuts off the compressed air to the spray gun, preventing painting without ventilation.
Filter Monitoring: We install Manometers (Magnehelic gauges) across the fan inlet to provide a visual "Change Filter" signal when the static pressure becomes too high.
LEV Certification (JKKP/DOSH): In Malaysia, paint booths are classified as Local Exhaust Ventilation (LEV). We provide the mandatory annual testing and certification by a registered Competent Person.
Turnkey MEP Execution: From the rooftop fan stack to the Spray Nozzles in a wet scrubber booth, we manage the entire mechanical and electrical installation.
Strategic Support: Based in Kuala Lumpur, we provide Vibration Analysis, motor rewinding, and 24/7 emergency repairs for commercial body shops and industrial coating lines.
