CBO
Connection Box
Description
CBO is a connection box for the diffusers. It is recommended for use in installations with limited vertical space. It
connects the diffuser with the horizontal duct so that the needed installation space height is less than 285 mm for the
largest nominal size.
Design
CBO is made from galvanized steel sheet. It has an immersed circular connection with nominal size for the diffuser.
The duct connection of larger nominal sizes has oval shape that reduces the required installation height profile.
