Helpful Tips

• MBI fans mount easily to attic joists at any angle.
• Rigid duct has a tendency to echo and magnify fan noise. To minimize sound levels, use flexible insulated duct. (Consult local building codes before selecting duct type)
• To minimize condensation in a duct, use flexible insulated duct when venting bathrooms or other warm or moist areas.
