Why It Is Quiet?
Mostly the range hood noise is the sound of air whooshing the steam away. The blower exhausts the air out, sucking the nearby air to one direction. For example, the house fan has bigger noise at higher speed, the sound is from the air collision, not the motor. High speed air collision is the cause of the powerful range hood.
What if we move the air collision from the kitchen area to above the ceiling?
The restaurant exhaust fans are on the roof; therefore, moving the blower to the attic is the solution for residential to eliminate the range hood noise. Same as the industrial inline blower, this Blower unit is in between the house exhaust vent and the range hood unit.
Powerful and Quiet, Still Using Your Own Hood
Keep your own hood unit but improve the exhausting performance and quiet operation. Mount the Blower unit in the attic, and keep the kitchen quiet.
Choose any of the 4 speeds
No control unit included. Please consult with your electrical technician before buying. Connect either one of 4 speeds wire to 120V Hot wire, then connect the Black wire to the Neutral wire from the power cord as shown in the 5 wires connection instruction.
