Sleeve/Ball Bearing Air Centrifugal Frameless Quiet Cooling Fan

Large Air Volume 67.47 CFM Frameless Bracket Cooling System Fan with PWM/Fg/Rd Function. Our frameless fans are quiet, consume minimal energy, and effectively reduce heat to safe levels.

Our advantage

We usually use a strong carton as the outer packing box, and at the same time add stuffing inside the carton, such as foam board, foam plastic, etc., to increase the cushioning and fixing effect.
