Square backplate with curved fitting

The Sistem Air square backplate with curved fitting is an essential component for connecting vacuum inlets to the piping network of a central vacuum system. Proper fixing of the backplate is crucial to ensure a stable and secure connection, maintaining vacuum throughout the system and guaranteeing optimal performance.

The curved fitting is designed to adapt to any wall type, featuring a depth of 7 cm, making it ideal even for installations in confined spaces without compromising functionality.

Backplate fixing

Backplate fixing requires precision to avoid issues during the installation of the vacuum inlet. The backplate must always be mounted flush with the plaster to ensure correct alignment and a perfect seal. These backplates are designed for easy installation on both masonry and plasterboard walls thanks to their dedicated fixing holes.

Installation on masonry and plasterboard

Installation can be carried out on solid walls or plasterboard. Below are the recommended installation procedures:

Masonry installation	Plasterboard installation
Fixing into masonry requires precision to ensure that, during the installation of the vacuum inlet, the sealing components engage perfectly. The backplate box must always be installed flush with the plaster.	Using the fixing holes on the mounting frame, the backplates can be installed onto plasterboard walls. The backplate box must always be positioned flush with the plaster.

Solutions for wall surface irregularities

If the wall surface presents irregularities that prevent proper adhesion of the backplate, extension components can be used to correct the installation without restoring the entire wall.

Recess up to 7 mm	Recess up to 12 mm	Recess over 12 mm
No correction required when the recess is up to 7 mm from the plaster surface.	For recesses up to 12 mm: shorten the vacuum inlet, move the O-ring inward and use the extension Art. 1457.1.	For recesses over 12 mm: use the same inlet extension Art. 1457.1 and trim it as required.

The Sistem Air square backplate with curved fitting is the ideal solution for anyone seeking a safe and efficient central vacuum system installation. With its innovative design, easy fixing system and dedicated features for managing wall irregularities, it is perfect for both residential and commercial applications—ensuring optimal performance, durability and ease of use.
