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 3’ air conditioning profile. This is a galvanised profile with an off-centre hooking semi-ring, and has only one upward bent-wing. This profile is particularly suitable for closure and blocking air systems. Dimensions and material are defined with the customer, according to his requirements.
