The Type SACA- auxiliary air fume hoods have been engineered to reduce the amount of costly conditioned air being exhausted from the room.

The large volume of air drawn from a room by a conventional type fume hood places a great burden on the room’s air conditioning and heating systems and greatly reduces the efficiency, while increasing the operational cost, of these systems.

With the SACA- auxiliary air fume hood, up to 70% of the air being exhausted by the hood is supplementary air - air introduced from an outside source at the top of the hood and distributed into the hood around the entire outside face of the hod (top, both sides and across the work surface). This supplementary air mingles with about 30% of the conditioned room and sweeps the fumes and vapors to the rear exhaust slots within the hood.

The supplementary (auxiliary) air is discharged into the hood around the entire outside face of the hood (top, down both sides and across the work surface) at a very low velocity, thereby avoiding high velocity air streams blasting at the front of the hood and into the chamber (which could be very uncomfortable to the hood operator).

The type SACA- auxiliary air fume hood is carefully engineered with the additional feature of an air foil surface which is curved to the air flow path, creating a smoother air flow pattern which can remove air effectively at a lower face velocity. Thus, less room air is used than a standard or conventional fume hood.

The SACA- fume hood superstructures are furnished with:

• The hood exterior is fabricated of 18 gauge, zinc-coated and bondarized steel with a chemical resistant enamel to match the base cabinet (furnished upon request).
• The interior is made of 1/4" thick, special heat, solvent and reagent resistant composition stone that is treated with a chemical resistant, clear vinyl for added protection. (Additional hood liners are available upon request, including a white modified resin/fiberglass, fiberglass reinforced polyester (FRP), and white polypropylene.)
• The fume hood baffles have two adjustable air flow dampers at the top and bottom for adjustment to light or heavy gases.
• The interior of the hood is illuminated with a vapor-proof incandescent light fixture for added visibility.
• A vertically rising front sash has a 1/4" thick, laminated safety glass window that is counter balanced with lead weights for fingertip movement. Sash stops are available, upon request, to further restrict the face opening of the hood.

Typical SACA- Fume Hoods

*Note:	Overall height shall be 9’-0" (108") when installed on to a 35-3/4" high base cabinet. Fume hoods may also be furnished without the support cabinet(s) and/or work surfaces.
Note:	A complete system, including chemical resistant duct work, is available.
