Model HPR
Pressure Relief Dampers
A pressure relief damper is a type of backdraft having an adjustable start-open pressure, which is capable of maintaining a relatively constant pressure at various airflows and closes upon a decrease in differential pressure. Greenheck's HPR damper series can be used as a safety device or a controlling device. It is designed to provide pressure relief up to 6 in. wg and 3000 fpm, respectively

Model BR
Barometric Relief Dampers
Barometric Relief Dampers are an eccentrically pivoted backdraft damper for low velocity applications. Barometric Relief Dampers may be mounted vertically or horizontally.
