Blauberg Axial Inline Fan, 10-Inch

Fan motor does not appear centered in can and product also seems a little out of round. Absolutely unusable as fan will not even turn for hitting the outside. Odd looking fan blades too. They do not extend outward but lean in at a 45 degree angle. I tried to bend them inward a little so they wouldn't hit but after about 30 seconds the centrifugal force pulls the blade outward and they start hitting again till the motor stops. No way I will install this and waste my time. Return ticket already printed.

Very well built! Bought this to replace a secondary blower fan that was too loud. Mounted it in my stack going into the attic for second floor hvac. Added a variable dial switch for control. At lower speeds it does tend to squeel.
