Insulated Flexible Air connector consisting
of two layers of pure aluminum and of two layers of
polyester binding a galvanized wire.
completely water and airtight, corrosion
resistant and can withstand high static pressure.
Resistance to high operating pressures is possible
because of the unique quadruple lamination process.
The large thickness of the walls of the internal duct (0.
/0.105 mm) as well as the small distance between the wire
helix (1 in, 25.2mm) allows to obtain high operating
pressures (15po WC, 3.7 KPa)
