Our expertise spans multiple industries, delivering custom-engineered LEV systems that effectively capture and remove harmful fumes, vapors, dust, and airborne contaminants directly at the source.
With strong engineering capability and industry experience, we design and build high-performance ventilation systems that improve workplace air quality, protect personnel health, and ensure environmental compliance with regulatory standards.
What is a Local Exhaust Ventilation System?
A local exhaust ventilation system (LEV) is an engineered solution designed to capture and remove airborne contaminants directly at their source before they spread into the workplace. These systems are essential in industries where dust, fumes, vapors, and gases are generated, helping maintain a safe and compliant working environment.
Unlike general ventilation, which dilutes contaminated air, LEV systems target pollutants at the point of origin—making them significantly more effective for hazardous processes.

HOW A LOCAL EXHAUST VENTILATION SYSTEM WORKS
A typical local exhaust ventilation system operates through a structured airflow process:
- Capture – Contaminants are collected at source via a hood
- Transport – Polluted air travels through ducting
- Filtration – Harmful particles are removed using filters or scrubbers
- Extraction – A fan drives airflow through the system
- Discharge – Clean or treated air is released via a chimney
These five core components ensure efficient contaminant removal and compliance with industrial standards.
Key Components of a Local Exhaust Ventilation System

Captures pollutants at the source (e.g., fume hood, canopy hood, extraction arm)
Ducting System
Transports contaminated air efficiently with minimal pressure loss
Air Cleaning System
Includes scrubbers, filters, or cyclones to remove harmful particles
Industrial Fan / Blower
Provides airflow and overcomes system resistance
Exhaust Chimney / Stack
Safely discharges treated air into the atmosphere while meeting emission standards

FREQUENTLY ASKED QUESTIONS (FAQ)
Can a local exhaust ventilation system reduce energy consumption in a facility?
Yes. A properly designed local exhaust ventilation system improves efficiency by capturing contaminants at the source, reducing the need for full-space air dilution. This targeted approach often lowers overall HVAC load and can contribute to long-term energy savings when engineered correctly.
What happens if a LEV system is undersized or poorly designed?
An undersized or poorly designed system will fail to capture contaminants effectively, leading to pollutant leakage into the workspace. This can increase health risks, reduce compliance performance, and cause higher maintenance costs due to system overload.
How does duct design affect the performance of a local exhaust ventilation system?
Duct design plays a critical role in maintaining proper airflow velocity. Poor duct sizing or layout can cause pressure loss, reduced suction efficiency, and particle buildup inside the system, significantly affecting overall performance.
What is the role of air velocity in a LEV system?
Air velocity determines how effectively contaminants are captured and transported through the system. If the velocity is too low, particles may escape; if too high, it may increase energy consumption and system wear. Proper balancing is essential for efficiency.
Is a local exhaust ventilation system required for environmental compliance in Malaysia?
In many industrial applications, yes. A properly designed LEV system helps facilities comply with environmental and occupational safety standards by controlling emissions and maintaining safe workplace air quality levels.
How does temperature affect LEV system performance?
High-temperature processes can impact air density and flow behavior, which may reduce capture efficiency. System design must account for thermal conditions to ensure stable performance under operating heat loads.
What is the lifespan of a properly designed LEV system?
With proper design, material selection, and regular maintenance, a LEV system can last many years. Components like fans, ducts, and hoods may require periodic servicing or replacement depending on operating conditions.
How does chimney height influence pollutant dispersion?
Chimney height directly affects how far and how safely treated air is dispersed into the atmosphere. A correctly calculated stack height prevents re-entrainment of contaminants and improves environmental compliance.
