Product Overview
Product Overview
JX3™ Downdraft Ventilation System With 3 Speeds

Developed and refined by Jenn-Air®, this downdraft ventilation system uses proximity ventilation that helps capture smoke, steam and odors at the cooking surface, whisking them down and out for a fresh, clean kitchen. It has been designed to provide optimal cooking performance, relying on a vertically mounted, 297 CFM motor class blower system.

17,000 BTU Ultra-High Output Burner

Enjoy the robust heat necessary for high-powered cooking techniques, whether searing a steak, stir-frying vegetables or rapidly boiling water.

5,000 BTU Ultra-Low Output Burner With Melt Cap

Provides the optimal temperature for gently cooking delicate sauces and foods.

DuraFinish® Protection

With excellence in every detail, DuraFinish® Protection helps keep your cooktop’s surface looking like new, resisting yellowing, staining and scratching.

Brass Burners With Removable Base

Elegant brass burners effectively direct heat for desired cooking results and can be removed for easy cleaning.

Convertible To Duct-Free Ventilation

Keep the view from your kitchen open and free from ductwork with this optional kit that allows conversion to duct-free ventilation.
