Mechanical ventilation connection-> 220x54 in, 220x54 out, 90deg angle with extraction point

I needed specific angled connector pieces for my in-house mechanical ventilation. Since the original parts were made from ABS, I decided to design and print the pieces;

I have made a variation of adapter pieces (please visit my account)

All parts can be printed without supports, providing a smooth airflow path to prevent whistling and dust accumulation. Some require assembly, I advise doing this with a filling glue (epoxy for example)

This part specifications;

Size in; 220x54mm
Size out; 220x54mm
Angle; 90 degrees (left)
Extras; Extraction point (110mm)

Confirmed working with;

• ROTHEIGNER mechanical ventilation piping
• any other brands with 220x54 outer dimensions piping
