Collapsing Channel 170x70x3000 mm

For the construction of a ventilation system under the floor is usually made of flat ventilation ducts, and the matching fittings. The metal collapsing channel is placed between the concrete or other mortar and then connected to the desired mechanical ventilation system. This creates a ventilation system constructed under the ground with which the whole house can be provided with fresh air.

The ventilation channels may of course also be used as fine structure. The fittings fit together perfectly, so that there is minimal loss of air.
