Abstract

In a distributing or collecting duct for ventilating ducts, the duct is divided in duct halves 1, 2, whereby one duct half 1 has branching openings 4 for connection of branching ducts 6, while the other duct half 2 has regulating aggregates 8, 9 for the branching openings 4, said aggregates being carried by tubular shafts 8<1>, 10 extending though the wall of the duct half 2. In that this duct half 2 is demountably connected to the duct half 1 having the branching openings, it might be removed for inspection and cleaning without positions of the regulating aggregates being changed. The tubular shafts 8<1>, 10 permit measuring differential pressure. The duct halves may be connected into desired lengths by means of a modular system. <IMAGE>
