Abstract
A guillotine damper for use in exhaust or like duct systems which must be entered by men for servicing has its frame provided with guides extending about the flow path from one end of the opening by which the blade enters an air tight bonnet to the other end thereof and enclosed by resiliently flexible metal seals. The blade has marginal channels coextensive with the guides with the channels closely fitting the guides and compressing the sides of the seals with zero leakage attained by sealing air discharged along the channels during movement of the blade and while the damper is closed.
