This is a fan for outdoor stoves and wood-burning stoves. It's a 6-blade design that operates from 50°C to 350°C. When placed on top of a stove, the blades automatically rotate with the temperature, circulating the air inside the tent. Comes with a thermometer. Used only once for a test run at a campsite. The thermometer is unused. Only the fan has been tested. This is a USED item and has been used outdoors, so please be aware of that. I used it on top of a regular kerosene stove. It's also recommended for home use, as it can circulate air without a separate circulator. - Model: SF606G - Brand: OUBRTS - Design: 6-blade design - Operating Temperature Range: 250°C (482°F) to 350°C (662°F) Thank you for looking.
