Key Features & Owner Benefits:

Powerful M1200 Blower Motor: The M1200 internal blower delivers a full 1,035 CFM of airflow at just 6.6 Sones, providing the power needed to clear heavy smoke, grease, and cooking odors from high-heat cooking on 42-inch cooktops and grills — all from inside your custom hood enclosure.
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 42-Inch Cooktop Enclosures: The 46⅜-inch width is specifically engineered to fit inside custom enclosures built over 42-inch cooktops and grills, providing over two inches of overhang coverage on each side for complete air capture across the full cooking surface.
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.
Industrial-Grade Stainless Steel Baffle Filters: Professional-grade stainless steel baffles intercept airborne grease before it can enter the ductwork, protecting your ventilation system and reducing the risk of grease-related fire hazards over time. Baffles are removable and dishwasher-safe for easy maintenance.
4-Speed Blower Control: Four distinct fan speed settings give you precise airflow control — from a gentle background setting for light cooking to full 1,035 CFM power for high-heat grilling and searing.
Compact 12½-Inch Profile: At just 12½ inches tall, this insert fits inside shallower custom canopy builds where a full 18-inch range hood would not fit, giving designers more flexibility in enclosure proportions and ceiling clearance.
Integrated LED Lighting: Built-in LED lights illuminate the cooking surface directly below, providing task lighting without the need for separate light fixtures inside the custom hood enclosure.

Professional Ventilation Inside Your Custom Hood Design

The Vent-A-Hood M-Series Wall Mount Liner Insert is purpose-built for homeowners and designers who want to create a one-of-a-kind hood exterior without sacrificing ventilation performance. Whether wrapped in reclaimed wood, clad in copper, finished in decorative plaster, or tiled to match the backsplash, the custom enclosure becomes the visual centerpiece while the liner insert handles the engineering. 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.

The M1200 blower motor is the workhorse of the M-Series lineup. At 1,035 CFM with four-speed control, it delivers enough power to handle professional-style cooking equipment, high-BTU gas burners, and grills while giving the cook precise speed adjustment for lighter tasks. At just 6.6 Sones at high speed, the M1200 keeps noise levels manageable even in open-concept kitchens and entertaining environments where conversation matters.

The 46⅜-inch width is specifically sized to fit inside custom enclosures built over 42-inch cooktops and grills, providing overhang coverage on both sides for complete air capture. The compact 12½-inch height allows the insert to sit inside shallower canopy builds where a full 18-inch range hood would not fit, and the 22½-inch depth accommodates standard-depth wall installations. Industrial-grade stainless steel baffle filters redirect airflow to separate grease from the air stream, channeling it away from the ductwork. The baffles are removable and dishwasher-safe. The corrosion-resistant canopy and stainless steel fascia assembly ensure durability in environments where heat, moisture, and grease vapor are constant factors — including outdoor covered patios when installed with a GFCI-protected circuit.

The M1200 blower includes the VP566 transition adapter, connecting directly to 10-inch round ducting for straightforward installation. Vent-A-Hood recommends mounting 30 inches above the cooking surface for optimal performance.
