The AMT flexible duct connector (a joint consisting of a layer
of fabric and two strips of sheet metal on both sides) can be
combined with PQ flange to fabricate square flexible duct
connectors or with the FLS flanges to fabricate round flexible
duct connectors. The flexible duct connectors eliminate
the noise and vibrationsfrom transmitting through the
ducting system. Widely used between the outlet mechanical
equipment generating noise and vibrations, such as air
handling units and fans, and the duct.
The design of the AMT flexible duct connector provides
excellent water and air tightness performance according to
class D requirements of EN 1507:2007. The tightness class
compliance was tested at 2000 Pa
