Shutters
Ventilation shutters seal off backdrafts in ducts, when the fan is not operating. They are gravity operated, i.e. they fall down on their own when used. Raptor Supplies offers exhaust, PVC, intake, gable, ceiling & supply shutters from Dayton, Americraft, Airmaster Fan and Vulcan Hart. They can be mounted on wall ducts and ceiling openings. Ceiling shutters feature tie rods on each side to uniformly open the ventilation duct when fans are operating. They have white coloured, galvanised steel louvres with felted edges to intake or exhaust air easily. Choose from a wide range of these shutters, available in galvanised steel, aluminium, PVC and fibreglass frame variants.
