Product Description

Product Description

The superstructure entrance of the Add Air Fume Hood is framed with inward angled members that minimize turbulence and provide smooth movement of air into the Hood. This design allows for efficient operation of the Fume Hood at face velocities ranging from 60 to 150 FPM.  Additionally, the built-in bypass feature above the Hood sash works to maintain a relatively constant face velocity at any sash position.  

The front mounted add air plenum of the Airfoil Add Air Fume Hood utilizes a series of diffusers and louvers to provide a uniform flow of supply air to the face of the Fume Hood. This uniform air flow allows for providing up to 70% of the overall air volume requirements of the Hood through the add air plenum.  As with other Fume Hoods, the Add Air Hood comes equipped with a full view laminated safety glass sash with a full width flush pull and counterweight for easy operation.

A lower airfoil acts as sash stop that provides a 1"" space for air to continuously flow into the Hood and across the work surface.  Double wall construction of the superstructure provides adequate space on both sides of the Hood for installation of service fixtures and routing of plumbing and electrical lines.  The lining of the interior work area of the Hood is white Resin-Chem with removable interior access panels on both sides. Removable exterior side panels provide easy access to fixtures and their service lines.

Installation Instructions

Since a smooth entry is vital, placement of the hood in the laboratory requires careful consideration. Layout of the laboratory and location of the chemical fume hood are important for optimal performance and minimal interference.

The interior of the Add Air Fume Hood is brightly lit by a maximum width dual fluorescent tube light fixture. The fixture is mounted behind a sealed safety glass panel to isolate the fixture from corrosive fumes and flammable vapors.  Replacement of fluorescent tubes is accomplished from the exterior top front of the Fume Hood superstructure.

Choose from the variety of optional service fixtures available. Service fixture and electrical outlet types and locations are to be specified by the customer to fit each particular application. Mounting holes are provided in the superstructure for final on-site installation of optional equipment.

Fume Hood Superstructures are available in widths from 48"" to 96"". Service and electrical fixtures shown are optional and must be ordered separately.

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.
