Manifolding laboratory exhaust in laboratory build-ings provides substantial energy and first-cost savings opportunities when compared to separately ducted, mul-tiple exhaust fans. A manifolded system also offers a num-ber of benefits, including:
�Increased fume dilution
�Enhanced personnel safety
�Augmented redundancy
�Improved design flexibility
�Probable energy recovery
Experience has shown that during laboratory retrofit projects, manifolded exhaust systems reduce construction costs and help avoid operational disruptions.
