Contact SupplierGravity dampers allow for the passage of air from inside the air unit to go towards the outside, to prevent overpressure inside the unit. The Gravity damper is all made of aluminium extruded profiles; the frame is assembled using the same profiles of the standard damper, whereas the damper blade and the accessories are new. The assembling, thanks to self-threading screws, needs no welding. The punching machine used to punch the profiles is the same used for the APS AROSIO dampers.
Materials of the Gravity Damper pitch 100mm/3.94in -- 80mm/3.15in
