Summit brings new innovation to small kitchens with the industry's first retractable range hood designed and engineered for recirculating use. HRTX18B is an 18 in. wide range hood in a glossy black powder-coated finish. The retractable design and 4 in. height create a low profile, minimalist look that seamlessly blends into your kitchen when not in use. For maximum surface coverage, the retractable hood slides out as needed.2 oversized aluminum mesh filters with a carbon layer absorb grease, smoke, and cooking odors. This hood is equipped with 2 pre-installed LED bulbs. Unlike traditional ductless ventilation, our retractable hood is exclusively designed, constructed, and rigorously tested for ductless applications where there is no access to outside venting. Instead of blocking airflow with a simple baffle, the Summit engineering team has created a quieter, more efficient system with smarter technology. It utilizes a cross-flow fan to rotate horizontally, redirecting air smoothly out of the front louvers set at a slight upwards angle to ensure smoke and odors won't be directed towards the user. This maintains laminar airflow, avoiding back pressure and minimizing the noise found in converted range hoods that use axial fans. Though it operates at a lower CFM, its effective airflow outperforms traditional axial fans with a more efficient, quiet performance. This range hood ships without a power cord and is designed to be hard-wired by a licensed professional.
