Microwaves over the range otr typically vent in two different ways.
In the first example the microwave over the range otr will vent through the manufacturer installed grease or carbon filter then directly through an exhaust port that is ducted to the outside of the structure.
Typically there might be a cabinet installed over the microwave and inside that cabinet will be duct work or a soffit above the microwave or a direct wall exhaust.
This eliminates smoke cooking odors moisture and hot air from remaining in the kitchen.
Over the range microwaves can vent to the outside or can recirculate the air.
All over the range spacemaker microwaves can be vented to the outside using an equivalent total of 140 feet of rigid 3 1 4 x 10 rectangular or rigid 6 round ducting.
Many times an over the range microwave that recirculates cooking fumes can be converted to exhaust to the outside.
If rectangular ducting please note.
Microwaves that vent to the outside force the air through duct work to the outdoors.
When considering venting in an over the range microwave there are ducted vents and recirculating vents.
