Fume Hood (Aerodynamic Design)

KEY FEATURES

Airfoil Design

• Rounded airfoil profile at the worktop edge
• Guides air smoothly into the hood, minimizing turbulence.
• Design As per Accordance to ASHRAE 110-1995)

 

Bypass Mechanism

• Maintains constant airflow even when sash height changes.
• Prevents high face velocity when sash is lowered

 

Optimized Baffle System

• Multi-slot baffles at back panel for uniform airflow.
• Captures light, medium, and heavy vapors efficiently

 

Sash System

• Vertical, horizontal, or combination sash.
• Shatter-resistant toughened glass.
• Often counterbalanced for smooth operation.

 

Worktop & Construction

• Aerodynamic raised edges prevent spills from reaching user
• Chemical-resistant surface of granite ( Black)
• Ergonomic design for operator comfort

 

Airflow Efficiency

• Designed for face velocity of 0.4–0.6 m/s (80–120 fpm).
• Stable airflow pattern reduces risk of fumes escaping.
• Energy-efficient – consumes less exhaust air compared to older designs.

 

Lighting & Visibility

• Flush-mounted LED/fluorescent light (no glare, shadow-free)

 

Safety & Monitoring

• Airflow monitor with alarm for low/high velocity.
• Sash position indicator / alarm.
• Explosion-proof electrical fittings (if need)
