Air King’s AK high volume series exhaust fans provide proper ventilation for large areas such as locker rooms, commercial bathrooms and other larger areas. The unit can be configured for top discharge mounting, straight through inline or right angle inline and the insulated housing ensures quiet operation. The unit easily installs using the included mounting angles that can also be adapted for 1/4-20 support rod installation for suspended ceilings. The 4-1/2 inch x 18-1/2 inch rectangle metal duct connector with dampers protects against backdrafts. The white, low profile metal grill is unobtrusive and complements almost all decors. The high volume series features two balanced polymeric dual inlet blowers that are permanently lubricated and suitable for continuous operation providing years of worry free operation with little to no maintenance required. Available in multiple CFM levels to meet the ventilation needs of your installation.
