V-Series Lab Exhaust Fans: A Smarter Solution for Lab Fume Exhaust Systems

In laboratory design across North America, it's common to see large, metal-clad exhaust systems with dilution nozzles towering over rooftops. These systems aim to minimize re-entrainment by diluting hazardous fumes with ambient air. While the intention is sound, laboratory exhaust design can also focus on high discharge velocity, plume rise, and effective contaminant dispersion. Enter the V-Series - a high-performance, corrosion-resistant lab exhaust fan developed by Plastec Ventilation.

What is a Laboratory Exhaust Fan?

A laboratory exhaust fan is a specialized ventilation system designed to remove hazardous fumes, chemical vapors, and contaminated air from laboratory environments. These fans are specifically engineered to handle the demanding conditions found in research labs, chemical facilities, pharmaceutical laboratories, and other areas where airborne contaminants are generated.

Role of Laboratory Exhaust Fans:

• Removes hazardous fumes and vapors: Extracts chemical gases, solvents, and harmful airborne particles to maintain a safer laboratory environment.

• Protects laboratory personnel: Helps reduce exposure to dangerous substances by continuously removing contaminated air from work areas.

• Maintains indoor air quality: Supports proper ventilation by preventing the buildup of chemical fumes and pollutants.

• Protects equipment and facilities: Reduces the risk of corrosion and damage caused by aggressive chemical vapors.

• Supports fume hood ventilation: Provides the necessary airflow to capture and safely exhaust contaminants generated during experiments and testing.

V-Series Laboratory Exhaust Fans Features

The V-Series lab exhaust fans are engineered for reliable fume extraction, corrosion resistance, and high-velocity airflow performance in demanding laboratory and chemical environments.

Corrosion-Resistant Polypropylene Construction

• 100% polypropylene construction: The V-Series is manufactured using polypropylene (PP), providing excellent resistance against aggressive chemicals commonly found in laboratory environments.

• Protection against corrosive substances: V-Series fans are made of polypropylene and provide resistance to many corrosive vapors and chemicals. Only Explosion Resistant versions are designed for explosive/flammable atmospheres. Temperature, concentration, humidity, and other factors affect chemical exposure, so each application should be assessed case by case.

High Velocity Discharge Performance

• High velocity laboratory exhaust fan design: The V-Series uses high-speed airflow to effectively remove contaminated air and improve exhaust dispersion.

• 3,000 FPM discharge velocity: The high-velocity discharge creates strong plume rise, helping move chemical fumes safely away from building air intake areas.

• ANSI Z9.5: ANSI/AIHA Z9.5 calls for a minimum stack discharge velocity of 3,000 fpm. The V-Series is designed for high discharge velocities, with an optional windband to add dilution.

• Improved fume dispersion: The momentum-driven exhaust design allows contaminants to disperse effectively without relying only on dilution with surrounding air.

Energy-Efficient Laboratory Ventilation

• Optimized system performance: The V-Series delivers effective exhaust performance without increasing airflow requirements unnecessarily.

Why High-Velocity Exhaust Is More Effective Than Dilution

Traditional exhaust approaches often rely on increasing airflow volume to dilute contaminants. However, laboratory exhaust systems are more effective when they focus on proper exhaust velocity, plume rise, and contaminant dispersion rather than simply moving larger amounts of air.

ANSI/AIHA Z9.5 calls for a minimum stack discharge velocity of 3,000 fpm. The V-Series is designed for high discharge velocities, with an optional windband to add dilution. High discharge velocity supports plume rise and helps disperse exhaust away from building air intake areas.

• Effective dispersion over simple dilution: Exhaust systems are designed to safely disperse hazardous fumes away from occupied areas and building air intakes rather than only reducing concentration through added airflow.

• High-velocity discharge improves plume rise: Increasing exhaust velocity helps create stronger upward momentum, allowing contaminated air to rise higher and disperse more effectively.

• Better performance with optimized airflow: A focused, high-momentum exhaust stream can achieve efficient contaminant removal without requiring oversized fans, additional ductwork, or excessive energy consumption.

• Improved compliance and safety: Proper plume management helps reduce the risk of chemical fumes returning to air intake areas or affecting nearby workspaces.

For laboratory environments, the V-Series high velocity laboratory exhaust fan uses momentum-driven discharge technology to improve exhaust dispersion while maintaining energy-efficient operation.

The Hidden Energy Costs of Excessive Air Dilution

Increasing airflow for dilution is one approach to laboratory exhaust design. However, exhaust velocity, plume rise, and contaminant dispersion are also important considerations when designing an effective laboratory exhaust system.

The V-Series laboratory exhaust fan uses high-velocity airflow to support plume rise and contaminant dispersion. Its design focuses on exhaust velocity and effective discharge rather than relying solely on increased airflow for dilution.
