The Trade-Wind VSL442-0-22BF VSL400 Series 42 Inch Wide Range Hood Insert is the only insert that meets your requirements on fergusonhome.com (aka build.com).

The cost of a large hood has to include the quality of stainless steel used (thickness and alloy -- lots of chromium and nickel involved), the quality of the welds and polish, and to some degree a factor for the manufacturer's reputation. Inserts hide much of the steel and can be made less expensively, but also may have dimensions that are not what you want.

The utility of in-line and remote blowers is that one can insert a silencer (e.g., Fantech LD10) into the duct path between hood and blower and greatly reduce the blade tip turbulence noise emitted from the hood and heard by the cook.

For least complication of getting one's project done, blowers that are compatible with hood controls are recommended. Conversely, one can always put a control somewhere else than in the hood.

Don't forget make-up air (MUA). Scour this forum for relevant discussions.

@kaseki thanks for the comment. I won't forget about makeup air, it is a lot of airflow!

Do you have any recommendations on hood inserts that may fit this criteria? Or some to stay away from at least? I feel like there is not a lot of opportunity around me to go see them for myself.

The cost criterion may be limiting. Frankly, this is not the category deserving economic restraint. Not only is good ventilation needed for minimizing household grease and ill effects from cooking effluent, but these issues justify the significant associated cost (both direct and architectural) of the ventilation system.

The Wolf Design Guide has their line of inserts, and you might as well review them for example designs. I have a Wolf Pro Island hood, not an insert, so I have never examined one. I also have an in-line silencer and roof blower (sold by Wolf, manufactured by Broan/NuTone).

Inserts are also called liners in many cases.

You might check out ModernAire to see what they may have. Note that they build to order if you have some concept in mind that makes sense.

BlueStar absorbed Abbaka, whom I had considered competent in blower design, and I see at their website that they have liners.

It is necessary to understand that after trillions of dollars that had no stored labor input were injected into the economy circa 2022, the inevitable delayed inflation effect is now upon us, and the cost of ventilation components in actual value is probably not yet even at catch-up with, say, 2008 price labor values, which themselves were soon to be driven up by 2008 banking crisis money flooding. Under some personal conditions and guesses abut the future, one might consider buying now and paying off with degraded dollars in the future versus cash now.
