This Fujitsu plenum box is connected to the fan coil unit by our filter installation frame. This allows the air filter to be withdrawn from the side or alternatively you can remove the plenum box from the frame by a quick release mechanism. Note that removal of the air inlet spigot on the fan coil unit is required to fit the plenum box assembly.
No air filter is supplied with this product.
Use the drop down velocity calculator to help you select the correct spigot configuration.
