Into the “air” category we present several versatile profile models suitable for closures, blocking, regulators and rotors for air flow generation and management systems, such as fans and air filters, air conditioners, air generation machines, pipes, ducts and more. In particular, this version is the ‘type 2’ air conditioning profile. This galvanised profile is especially suitable for control dampers for smoke evacuation systems (smoke/ fire dumper), as it has an off-centre hooking semi-ring, and it has no bent-wings, to give greater grip when closed. Dimensions, material and treatments are defined according to customer requirements.
