Product Description
Product Description
Add-air fume hoods, also known as included air, make-up air, and auxiliary air hoods are those that supply their own air directly through a blower or duct run. These energy-saving exhaust hoods are less cost-efficient than other hoods (with the start-up costs of additional supply fans and ductwork), but offer more in long-term savings with energy-efficiency.
We are the best source for add air fume hoods in the world. Unlike other chemical fume hoods on the market, this product uses a plenum to regulate the stream of outside air in an isolated space. This provides better ventilation for laboratories, classrooms, and research facilities.

Installation Instructions
It is up to the operator to know how to adjust flows for a particular need. Pay attention to proper flow and remember to adjust the baffles according to the work being done. Keep the following in mind when routinely checking the hood for adequate flow and velocity:
- Are there dead spots in the face velocity or inside the hood and are they located where capture is needed? We recommend face velocity be checked using a grid pattern with a minimum of six readings, and that readings not differ by more than ten percent. Alternately, air current or smoke tubes are useful in detecting dead or low-flow zones.
- Where is capture needed? Are you working with vapors that are lighter than air? Heavier? If they are heavier than air, then the dampers should be adjusted to capture at the bottom of the hood (i.e., open the bottom slot and close down the upper one). If storage or equipment is blocking the lower slot, this may hinder flow and thus proper capture. One quick fix is to install a shelf above the lower baffle so reagents and chemicals stored on the shelf do not block the lower slot. If the vapors are lighter than air, you may be okay with some storage in the hood. Use smoke tests to confirm this.

FAQ
Why Does Your Lab Need a Fume Hood?
If you work with potentially harmful materials in your laboratory, a fume hood is an essential piece of equipment to keep researchers, employees, teachers or students safe.
While many different types of fume hoods exist, the basic principle behind them all is a work space with one open side that allows fresh air to be drawn into the hood. The moveable glass panel with the open side is called the sash. Even in the closed position, sashes still allow air to enter the fume hood. The air is then released through an exhaust vent or duct.
All work with radioactive material, perchloric acid or other material that could be explosive or corrosive, and chemicals that release noxious fumes should be done inside a fume hood.
Ideally, fume hoods should be located in a part of your lab with low foot traffic to minimize the amount of turbulence in the air that could allow contaminants to escape into the lab. Our Installation Team has had more than twenty years of experience and can help you determine the best place to put your new fume hood.
