CASE OF AN INDIVIDUAL DUCT
For a rectangular duct, the constraints are the following:
▪
The top platform must be rectangular and measure at least 600 x 600 mm.
▪
The opening cross-section of the duct must not exceed 245 x 245 mm if it is
desired to avoid reducing its cross-section.
▪
The fan must be centred on the duct.
For a circular duct, the constraints are the following:
▪
The top platform must be rectangular and measure at least 600 x 600 mm.
▪
The opening cross-section of the duct must not exceed Ø350 mm if it is
desired to avoid reducing its cross-section.
▪
The fan must be centred on the duct.
CASE OF DUCTS GROUPED UNDER A SINGLE FAN
For all grouped ducts configurations, an adaptation plenum is necessary. The plenum must:
▪
provide a top platform measuring at least 600 x 600 mm.
▪
provide a circular outlet Ø350 mm centred on the stack.
▪
ensure a minimum height of air between the end of the stack and the outlet section Ø350 mm, that is to say 120
mm or 180 mm.
▪
The fan must be centred on the outlet section Ø350 mm.
