FLX-BP pressed ventilation bends are used with the FLX-HDPE/
FLX-HDPE-A semi-rigid ducting. The bend is made by seam
welding for improved installation airtightness.
The duct is connected by inserting it into the bend.
The pressed form of the ventilation bend helps to reduce
the airflow resistance and the pressure loss.
The airtightness class can be increased to class B by wrapping
the joints with the TAL, MET or DUCT sealing tape.
