Hi everyone. Been reading a lot on this site and got tons of good info.

Just purchased and installed a Best by Broan 48 inch range hood with external 1200 cfm blower. Used rigid duct, Fantec silencer, one 45 degree bend, one 90 degree and a total physical length of 13 feet - calculated at maybe 25 feet. Hood is super quiet - basically you can not hear anything until until about mid speeds (variable adjustement) and max speed is mostly lots of air rushing thru the baffles - lots of air.

Question - how do I know if the hood blower is working properly. For example I don't feel lots of air being drawn in down below the baffles. Air is felt about 6 inches below the baffles and a sheet of paper will stick to the baffles as others stated for a test. Should the air being drawn in be felt lower or is this about normal. I also had a window open when testing. How much below the baffles should I feel air being drawn in when on full speed

Thanks
