Fantech's new Bathroom Fan Contour Grilles have been scientifically designed to work as either Supply or Exhaust Grilles. Well developed Coanda effect disperses air along the ceiling thus eliminating cold drafts. These bathroom fan grilles also work well in heated applications. 
Grilles are manufactured of flame retardant, polypropylene that resists yellowing. White matte finish on these bathroom fan grilles can be painted to match walls or ceiling. This bathroom fan grille is for a 4" duct.
