ND-BR Series with PSP Accessory
Exhaust-Only Hood with Front & Rear Make-Up Air Plenums
Captive-Aire's exhaust only, low CFM ventilation hood is ETL Listed for use over 450°F, 600°F and 700° F cooking
surface temperatures. The combination of the rear and front supply plenums provide up to 90% make-up air.
Offering A Fully Integrated Package, Pre-Engineered For Optimum Performance
ADVANTAGES
Exhaust Flow Rates: Superior exhaust flow rates. A 4' Hood can operate at 150 CFM/ft or 600 total CFM.
ETL Listed: ETL Listed for use over 450°F, 600°F and 700°F cook ing 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.
Front Design: Double Wall front design prevents condensation and directs greaseexhaust filter bank.
Stainless Steel Construction: Polished stainless steel on the interior and exterior of the front enhance
aesthetics.
Sturdy Construction: Sturdy stainless steel construction with double wall, insulated front panel.
Pre-wiring at Factory: Factory pre-wired lighting to illuminate the cooking surface.
Industrial Grease Baffle Filters: All hoods come standard with aluminum baffle filters. Stainless steel
filters are optional. High velocity cartridge filters are available on the CND series.
Clearance to Combustibles: Optional integral clearance to combustibles reduction system to meet NFPA
96 requirements.
Face Mounted Controls: Optional UL Listed light and fan control switches flush mounted and pre-wired
through electrical chaseway.
Capture & Containment: 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.
ETL Listed Fire Damper: Optional ETL Listed exhaust fire damper on the ND-100 model.
Rear Make-Up Air Plenum: Air delivered through the front of the rear plenum (BR-back return) creates a
positive pressure barrier behind the cooking equipment to keep smoke and grease laden vapors moving
upward toward the hood.
Directs Make-Up Air Into Hood's Capture Area: A large percentage of the make-up air discharged from
the front perforated supply plenum(PSP) is directed into the hood's capture area.
Even Distribution of Make-Up Air Across Length of Hood: The perforated supply plenum(PSP) delivers
the make-up air evenly along the length of the hood.

Rear make-up air plenum is constructed of stainless steel to match the hood and discharges air via
stainless steel perforated panels at the bottom of the plenum.
A perforated supply plenum(PSP) delivers up to 80% make-up air(MUA). MUA emitted at low discharge
velocities. Evenly distributes MUA along the length of the hood. Directs a large percentage of MUA into
hood's capture area.
