Displaced air cannot renew itself and this can lead to many health and safety problems all round. Negative air can cause a backdraft down a flue which can start a fire or emit carbon monoxide fumes which are highly dangerous.
For home use, cooker hoods cannot have a CFM (cubic feet per minute) higher than 399 to be compliant with the code. Special sized ducting must be used to be compliant with the code. Round ducting with as few 90degree bends as possible should be 6 round, or 3.25x10 for the rectangle. Bends in the ducting will restrict air. For restaurants and professional cooking ranges an 8-10 width is recommended.
For manufacturing plants cross contamination is one of the causes of depleting the air supply when doors are opened to let in fresh air. This has led to the code specifying that makeup air equipment is used to replace the displaced air. In the Boston are and surrounds inspectors are checking for compliance as this applies not only to homes, but to manufacturing plants, hospitals and public building too.
These either heat up or cool down an area without introducing fresh air, so adequate equipment is necessary to adjust this imbalance. This is introduced when a building is in a negative air pressure state. This happens when the lack of enough makeup then causes the increase of static pressure that the exhaust fans to take care of. A reduction in CFM which is cubic feet per minute of air from the exhaust fans takes place resulting in negative air pressure.
Broan manufactures and supplies these three very inexpensive tools: A direct wired damper MD6T and MD8T, Universal Pressure dampers MD6TU and MD8TU, and Fresh Air Wall Caps 641FA and 643FA at a cost of around $300. If you are a handy-man you could sort it out yourself.
This does not only apply to kitchens but to plants in manufacturing industries too, as technology gets savvier, their plant infrastructure needs to be up to the job of keeping their atmosphere at the right temperatures, and this is where makeup equipment is necessary.
For home, manufacturing or professional use, your airflow exhausted must be replaced and this is not a difficult job if you realise that it only takes a few small parts added to your ducting system to allow for the displaced air to be replaced at the same time you are using the ventilation system already in use. The equipment mentioned here is readily available at hardware suppliers and electrical outlets.
