    For over forty years and counting, Air King continues to demonstrate their reputation for making high quality ventilation products. The Air King FRAK50S is a 50 CFM bathroom exhaust fan with a low-profile grille that blends right into the ceiling. This Air King line of fire rated exhaust fans have been tested and UL listed for use in wood frame construction. They are designed to automatically shut off and seal the duct if high temperatures are detected. The FRAK50S is simple to install with included adjustable hanging brackets and features a 4-inch metal duct collar with a built-in damper to protect against backdrafts and ensure quiet operation. At 0.6 sones, the FRAK50S is truly a quiet fan. Effective for areas up to 60 square feet, the Air King FRAK50S can provide exceptional ventilation in most home applications.
  • Quiet Operation
  • With an air flow of 50 CFM and a sound level of only 0.6 sones, the Air King FRAK50S provides effective ventilation while being one of the quietest bathroom fans on the market.
  • Fire Rated System
  • The FRAK50S exhaust fan is UL rated to be installed into wood frame construction and are designed to automatically shut off and seal the duct if high temperatures are detected.
  • Back Draft Damper
  • A metallic, fire rated back draft damper comes included with the FRAK50S to eliminate back drafts and keep volume levels to a minimum.
  • Low-Profile Grille
  • The low-profile grille featured on the FRAK50S sits nearly flush with the ceiling, preventing the fan from detracting from your bathroom aesthetic while still adhering to fire rating regulations.
  • Simple Installation
  • Adjustable mounting brackets included with the FRAK80 allow for quick and easy installation.
  • Warranty
  • Every Air King product is warranted against defects in workmanship and materials for 1 year from the date of the purchase. During the warranty period, Air King will repair or replace any defective parts, or replace the entire product.
