Pneumatic conveyance systems
Scope of application
Pneumatic conveyance systems or technical air suction systems, which are charged with chippings, fibers, residual materials, etc., and which therefore require a free pipe or duct cross-section.
Sealing system for pipe and duct connection
The conveyance system closure is designed based on the “hole offset” principle. A distance piece (sealing system), whose form and dimension is equivalent to the pipe system, is permanently connected to the barrier element. The pipe system must be separated to install the fire protection closures. The incoming and outgoing pipe system is fastened on both sides at the conveyance system closure using flanges or pipe connections. The connection between the pipe systems will be established by a distance piece (opening condition) that moves in-between. The distance piece is equipped on both sides with sealing lips that can be blown up by compressed air to establish an absolute pressure-tight connection. In case of a manual tripping/fire alarm, the sealing lips will be depressurized and contract, the distance piece moves now out of the pipe system with adequate clearance and will be replaced by the locking element, which guarantees the fire protection.
