PVC 45° MF branches allow safe and efficient pipe splitting in central vacuum systems, providing a reliable male–female connection for multi-point installations.
The PVC 45° MF wye is an essential fitting for building central vacuum systems, allowing safe and precise splitting of the main line while maintaining optimal airflow.
The 45° male–female PVC wye is available in the following diameters:
| To create multiple vacuum inlets, the main line must be split using 45° FF or MF wyes. This operation allows horizontal distribution on the same floor or the creation of vertical risers to serve multiple levels. | ![]() |
| In multi-storey buildings, you can either develop a single vertical riser with horizontal branches on each floor (A), or create multiple lines joined into a single collector at the central vacuum unit (B). The number of wyes required is always one less than the number of inlets (e.g. 5 inlets = 4 wyes). | ![]() |
| The wye must always be installed according to the airflow direction, as shown by the ➜ symbol. Incorrect installation will inevitably cause clogging in the system. | ![]() |
All Sistem Air piping components are designed to ensure perfect coupling between the PVC pipe network and the fittings, guaranteeing a stable and secure connection. Pipe joints are made using cold-weld PVC adhesive, which provides an airtight, long-lasting seal, preventing air leaks and preserving the efficiency of the system.
