Non Return Dampers

Abeer is a leading supplier of Non-Return Damper which is an HVAC damper being used in the places where only one direction is required to flow air. Depending on the application, non-return dampers may be placed on the wall or duct. They are most frequently used in the presence of fans where the blades are only opened when the fan starts and the blades close because the fans stop.

Abeer‘NRD’ type models are also named as ‘self closing dampers ‘or ‘Back pressure dampers ‘or ‘gravity dampers’ or ‘pressure relief dampers’. These dampers are air operated, opening or closing dampers for intake, discharge and pressure relief vents in air conditioning systems.

Non-return dampers supplied by Abeer are intended for use in commercial air conditioning systems in the entry and discharge opening.
