Broan

ALT4306SS

• SmartSense™ Automated Ventilation – uses an infrared sensor to detect heat from the cooktop and automatically adjusts fan speed to clear smoke and cooking odors without manual input.

• Code Ready Technology (CRT) – allows installers to reduce airflow to 300 or 400 CFM to meet local building codes or make‑up air requirements.

• ENERGY STAR® certified and Title 24 compliant – meets strict energy‑efficiency standards and California Title 24 requirements to help reduce energy use and support code compliance.

• EZ1® one‑person installation system – includes special mounting brackets so a single installer can mount the hood quickly and securely, saving time and labor.

• Alta Series under‑cabinet design – low‑profile 30" stainless steel hood fits neatly under standard cabinetry for a built‑in, modern look.

• Most powerful under‑cabinet Broan hood – delivers up to 640 Max Blower CFM to handle heavy cooking, high‑heat searing, and frequent frying.

• High capture efficiency – engineered to capture up to 98.5% of cooking pollutants at the source, helping keep kitchen air cleaner.

• Dual blower system – two internal blowers provide strong, even airflow across the cooking surface for more effective ventilation.

• Quiet performance – operates as low as 0.8 sones on the quietest setting for comfortable everyday use while cooking and conversing.

• Three-speed blower control – offers low, medium, and high fan speeds so you can match ventilation power to light simmering or heavy frying.

• Infrared touch controls – underside touch panel lets you adjust fan speeds and lighting levels with a simple tap for a sleek, easy‑clean interface.

• Bright 2‑level LED lighting – integrated, heat‑resistant LED modules provide bright task lighting with two intensity levels to illuminate the cooktop.

• Included LED light modules – long‑lasting, energy‑efficient LEDs are factory‑installed so no separate bulbs are required.

• Fully enclosed bottom design – smooth underside with no exposed mechanical parts improves appearance and makes wipe‑down cleaning easier.

• Hybrid baffle filters – high‑efficiency baffle‑style filters with mesh capture more grease and particulates while maintaining strong airflow.

• Dishwasher‑safe grease filters – removable hybrid baffle filters can be placed directly in the dishwasher for quick, thorough cleaning.

• Convertible venting options – supports top or rear ducted installation, or non‑ducted recirculating operation with optional charcoal filters (HPF30, sold separately).

• Multiple duct connections – compatible with 3¼" x 10" rectangular (top or rear) or 7" round (top) ducting to fit common kitchen vent configurations.

• Ducted or ductless capability – can be installed as a traditional vent‑to‑outside hood or as a recirculating hood where exterior venting is not possible.

• Optional charcoal filter kit – available HPF30 charcoal filters (sold separately) help remove odors when the hood is used in non‑ducted mode.

• Optional power cord kit – can be hardwired or used with the HCK44 power cord kit (sold separately) for plug‑in installation flexibility.

• Optional Universal make‑up air damper compatibility – works with MD6TU, MD8TU, or MD10TU dampers (sold separately) to automatically bring in fresh air when the hood runs, helping balance household air pressure.

• ADA‑compliant capable – can be installed to meet ADA guidelines when paired with the HAWRK5 low‑voltage wall switch kit (sold separately).

• Under‑cabinet mounting – designed to install beneath 30" wide cabinets, ideal for standard ranges and cooktops.

• Low profile height – approximately 5.12" high to maintain sightlines and maximize headroom over the cooking surface.

• Stainless steel construction – durable, corrosion‑resistant stainless finish complements a wide range of kitchen appliance styles.

• Integrated backdraft damper – built‑in damper helps prevent outside air from coming back through the duct when the hood is off.

• Delay‑off function (where available) – allows the fan to run for a short period after cooking to clear residual smoke and odors, then shut off automatically.

• LED indicator lights – visual indicators confirm fan speed and lighting status at a glance.

• Automatic fan operation – SmartSense system can start and adjust the fan automatically when it detects sufficient heat, adding a layer of protection against lingering smoke.

• 0.8–8.5 sones noise range – offers quiet operation on low with higher performance available on maximum speed when needed.

• 30" width – sized to match most 30‑inch ranges and cooktops for full coverage of the cooking area.

• 20.06" depth – extends far enough over the cooktop to effectively capture rising steam and smoke.

• 120V, 2‑amp electrical requirement – standard household electrical connection simplifies installation in most kitchens.

• 228‑watt total power draw – balances strong ventilation performance with energy‑conscious operation.

• HVI certified performance – tested and certified by the Home Ventilating Institute for verified airflow and sound ratings.

• Residential indoor use – designed specifically for indoor residential kitchens, not for outdoor or commercial applications.

• Manufacturer warranty coverage – includes a limited product warranty and extended coverage on the LED modules (terms vary by region).
