SND Series

Exhaust Only Hood for Low Ceiling Heights

The SND model is the sloped-front version of CaptiveAire's flagship ND hood. This wall canopy, Type I,
exhaust-only unit operates at low CFM and is the hood of choice for low-ceiling applications. It is ETL Listed for
use over 400°F and 600°F cooking surface temperatures.

Offering A Fully Integrated Package, Pre-Engineered For Optimum Performance

ADVANTAGES

Superior exhaust flow rates (A 4' Hood can operate at 228 CFM/ft or 912 total CFM.)
ETL Listed for use over 400°F and 600°F cooking surface temperatures, provides flexibility in designing
kitchen ventilation systems. ETL Listed to Canadian safety standards, ETL Sanitation Listed and built in
accordance with NFPA 96.
Sloped front for low ceiling applications.
Front design prevents condensation and directs grease-laden vapors toward the exhaust filter bank.
Polished stainless steel on the interior and exterior of the front enhance aesthetics.
Sturdy stainless steel construction with double wall, insulated front panel.
Factory pre-wired lighting to illuminate the cooking surface.
All hoods come standard with aluminum baffle filters. Captrate Combo®, Captrate Solo®, high efficiency
stainless steel baffle, and stainless steel baffle filters are optional. High velocity cartridge filters are
available on the CSND series.
Optional integral clearance to combustibles reduction system to meet NFPA 96 requirements.
Optional UL Listed light and fan control switches flush mounted and pre-wired through electrical chaseway.
Exceptional capture and containment of cooking vapors. This is accomplished with the signature ND
"triangle" on the front of the hood's capture area and the "C-shaped" design of the hood's capture area
(see the drawing above).
