Abstract

The flap unit, in particular, fire protection flap unit comprises a pivotable barrier blade (4) located in a housing (1) or a pipe section provided with a seal (6) which consists at least in parts of an open-cell foam and is covered at least in parts with a flexible coating not penetrable by gases, so that in the closed state of the flap unit the circumferential gap between the housing (or pipe section) surface and the barrier blade is closed for gas flow. Also claimed is a circumferential seal forming a part of the flap unit.
