iPower 4 inch Backdraft Shutter Damper Back Draft Blocker, One-Way Airflow Ducting Insert Backflow Preventer with 2 Inline Springs Loaded Folding Blades, 4", HVAC Extractor Fan Vent, Range Hoods

Q: Can anyone tell me the temperature rating of this fan? Can it be used as a forced hot air booster fan?

I'm not exactly sure what the rating is but I believe it's likely to handle it. I mean how hot is the air? If it will melt skin or something then I wouldn't use it... Otherwise should be fine blowing through multiple hoods with 1000s.

Q: What is the wattage of this fan?

I just went out and checked the label on the fan: It draws .9 amps at 95 watts. It blows a lot harder than you would expect for that wattage.

Q: Is it 770 or 430cfm the spec seems conflicting. Anyone knows the watts

I see your confusion in the specs. I didn't notice that when I bought one. Pretty sure it's 770. I added one of these to it because it was so powerful: http://www.amazon.com/Active-Air-ACSC-Speed-Adjuster/dp/B007TFTITS/ref=pd_sim_lg_2?ie=UTF8&refRID=0370HH92VNG69ATPWJ67
