Important Notes for Multiple Fume Hoods Sharing One Exhaust Fan

Shared exhaust fan systems for multiple fume hoods require careful balancing and monitoring to ensure each fume hood maintains adequate containment.

Key Points:

• Install individual airflow indicators on each fume hood for monitoring.
• Use butterfly dampers for balancing between fume hoods.
• Consider emergency exhaust capabilities for hazardous materials.
• Schedule regular inspection of the shared ductwork for corrosion or buildup.
