Key Features & Owner Benefits:
- Magic Lung® Whisper Quiet Technology: The patented Magic Lung® system delivers 900 CFM of ventilation power while operating at just 6.3 Sones — one of the quietest sound levels in the entire Vent-A-Hood lineup. The centrifugal blower design captures 99% of cooking grease, steam, and odors 100% of the time.
- Equivalent 1,350 CFM Performance: The 900 CFM Magic Lung® blower delivers airflow equivalent to 1,350 CFM from conventional hood systems, providing substantially more effective air clearing per unit of rated power — superior performance without the noise penalty of higher-CFM systems.
- Liner Insert Design for Custom Hoods: This insert installs inside a custom-built hood enclosure, giving homeowners and designers complete freedom to create the exterior they want — wood, plaster, copper, tile, or any material — while keeping Vent-A-Hood's professional-grade ventilation technology hidden inside.
- Sized for 36-Inch Cooktop Enclosures: The 40⅜-inch width is specifically engineered to fit inside custom enclosures built over standard 36-inch cooktops and grills, providing over two inches of overhang coverage on each side for complete air capture across the full cooking surface.
- SensaSource® Intelligent Heat Detection: An integrated heat sensor continuously monitors cooking surface temperature and automatically adjusts blower speed as conditions change, maintaining optimal grease capture and fire safety without manual intervention.
- Corrosion-Resistant Canopy & Stainless Steel Fascia: The insert features a corrosion-resistant canopy paired with a 304-grade stainless steel fascia assembly, ensuring long-term durability in both indoor and outdoor environments where heat, moisture, and grease are constant factors.
- Snap-Apart Blower Housing: The Magic Lung® housing is designed to snap apart by hand for quick, thorough cleaning of internal components — no special tools or solvents required.
- Variable LED Lighting with 2-Level Dimming: Integrated LED lights provide bright task lighting for active cooking and a dimmed ambient setting for everyday use, covering the full cooking surface below.
Premium Performance and the Quietest Operation in a Compact Insert
The Vent-A-Hood 40⅜-Inch Premium Liner Insert is purpose-built for homeowners and designers who want to create a one-of-a-kind hood exterior without sacrificing ventilation performance — and who value whisper-quiet operation above all else. At 6.3 Sones, this is one of the quietest high-performance inserts in the Vent-A-Hood lineup, making it an ideal choice for open-concept kitchens and covered outdoor patios where noise matters as much as airflow. Since 1933, Vent-A-Hood has focused exclusively on ventilation engineering — a single-category expertise that has produced innovations no full-line appliance manufacturer has replicated.
At the core of this insert is the patented Magic Lung® centrifugal blower. Unlike conventional range hoods that pull air through layered mesh or baffle filters, the Magic Lung® spins air at high velocity, liquefying grease vapor through centrifugal force and channeling it into a removable collection area accessed through the snap-apart blower housing. The result is a verified 99% grease capture rate, measurably lower long-term maintenance, and a dedicated fire barrier at the blower housing.
At 900 CFM — equivalent to 1,350 CFM from conventional systems — this insert delivers more effective ventilation than the raw CFM number suggests. For homeowners who cook regularly but don't require the maximum 1,200 CFM output, the 900 CFM blower provides an ideal balance of power and noise reduction, operating 0.3 Sones quieter than the 1,200 CFM configuration while still clearing smoke, grease, and odors from high-heat cooking. The SensaSource® heat sensor ensures the blower responds automatically to changing cooking conditions, while the two-speed rocker control gives the cook direct manual access when preferred.
The 40⅜-inch width is sized to fit inside custom enclosures built over standard 36-inch cooktops, providing overhang coverage on both sides. The compact 12-inch height allows the insert to sit inside shallower canopy builds where a full 18-inch range hood would not fit. The corrosion-resistant canopy and stainless steel fascia assembly ensure durability in all environments — including outdoor covered patios when installed with a GFCI-protected circuit.
