Description & Features
The Broan 273603 downdraft ventilation system is a sleek, space‑saving solution designed for modern kitchens that want powerful performance without a bulky overhead hood. Engineered for 36-inch cooktops, this unit delivers up to 600 Max CFM of ventilation power, efficiently capturing smoke, steam, and cooking odors right at the cooking surface so your kitchen air stays fresher and cleaner while you cook. One of its standout advantages is the innovative downdraft design that remains hidden until needed; with a simple touch of a button, the vent automatically rises into position, then retracts to sit virtually flush with your countertop when you’re done, preserving clean sightlines and maximizing the open feel of your space.

Another key benefit of the Broan 273603 is its flexible installation and space-conscious engineering. The blower can discharge to the right, left, or straight down and even slides side-to-side, giving installers more options to work around cabinets, joists, or limited under-counter room. This thoughtful design helps you make the most of valuable cabinet storage while still enjoying robust, ducted ventilation performance. The standard stainless steel cover complements a wide range of appliance finishes and countertop materials, adding a professional, built-in look that blends seamlessly with both contemporary and traditional kitchen styles.

Everyday operation is designed to be intuitive and discreet. The infinitely adjustable speed control is mounted flush on the side of the unit, keeping the front profile clean while still being easy to reach, so you can fine-tune the fan speed from a gentle simmer setting to maximum draw for high-heat searing. Aluminum filters help trap grease effectively and are easily accessible from the front panel for quick removal and cleaning, simplifying routine maintenance. At a generous 36-inch width, this downdraft is well-suited to larger cooktops and multi-burner configurations, offering broad coverage across the cooking surface. Whether you’re planning a new build or upgrading an existing kitchen, the Broan 273603 provides a premium combination of hidden design, strong airflow, and installation versatility that sets it apart from many conventional range hoods.

Broan® Elite 27000 Series design – premium downdraft ventilation series engineered for powerful performance and a sleek, built‑in look.
HVI Certified performance – independently tested to meet Home Ventilating Institute standards for airflow and sound, so published CFM and sones are verified.
UL Listed safety – tested and certified to meet nationally recognized electrical and fire‑safety standards for household appliances.

600 Max CFM internal blower – high‑capacity blower quickly removes smoke, steam, and cooking odors to help keep kitchen air cleaner.
36-inch downdraft configuration – installs directly behind most 36" cooktops to capture rising smoke and steam at the source.
Innovative downdraft ventilation system – pulls air across the cooking surface and down through the vent, ideal where a traditional overhead hood is not desired.
Automatically raises with the touch of a button – lift mechanism raises the vent up from the countertop for use and lowers it out of sight when not needed.
Disappears flush with the cooktop surface – retracts completely into the countertop for a clean, unobtrusive appearance.
Space‑saving under‑counter design – slim housing preserves valuable cabinet and storage space beneath the cooktop.
Infinitely adjustable variable speed control – rotary control lets you fine‑tune fan speed from low to high for precise ventilation.
Side‑mounted flush control knob – control is recessed into the side of the unit, keeping the front clean while remaining easy to reach.
3‑sone sound rating (on typical setting) – engineered for relatively quiet operation compared with many high‑CFM hoods.

Stainless steel cover standard – durable, modern stainless panel matches a wide range of cooktop and appliance finishes.
Optional color‑matched covers available – compatible with separately sold covers in White, Biscuit, and Black to coordinate with different kitchen styles.
Sleek, trim styling – low‑profile design complements both contemporary and traditional cooktops without dominating the space.

Compatible with virtually all self‑contained cooktops – designed to work with most standard gas and electric cooktops (not for use with slide‑in ranges).
Flexible 3‑way discharge – blower can discharge right, left, or down to accommodate different duct routing in the cabinet.
Side‑to‑side sliding blower housing – blower box can shift laterally to help avoid floor joists or obstructions during installation.
Ducted‑only ventilation – vents air outdoors for effective removal of moisture, heat, and airborne grease (not convertible to ductless).
Horizontal or vertical duct direction – supports both horizontal (3¼" x 10") and vertical (6" round) duct connections for layout flexibility.

Aluminum mesh grease filters – capture airborne grease and particulates to help protect ductwork and maintain performance.
Dishwasher‑safe filters – removable filters can be cleaned in a dishwasher for easy maintenance and long‑term efficiency.
Front access panel for cleaning – front service panel allows convenient access to interior components and filters without uninstalling the unit.

Rotary mechanical controls – simple, reliable knob operation with no complex electronics.
No built‑in lighting – designed to pair with existing cooktop or recessed lighting without adding extra light sources.
No recirculating or ductless mode – ensures all captured air is exhausted outside rather than filtered and returned to the room.

36" width, 7" depth, ~29.5" height – compact chassis fits standard 36‑inch cooktop installations with minimal counter overhang.
Internal blower included – comes with built‑in blower, eliminating the need to purchase a separate internal motor.
120V, 4.0A, 480W electrical rating – standard household power requirement for straightforward hookup.

1‑year limited parts and labor warranty – manufacturer coverage against defects in materials and workmanship for added peace of mind.
ENERGY STAR® not required – high‑performance, on‑demand ventilation where efficiency labeling is not typically applied to downdraft hoods.
ADA non‑compliant classification – standard installation height and control placement designed for typical, non‑ADA kitchen layouts.
