Blowing machine
A blowing machine is a machine that can fill cavities with the help of a stream of air. One method of laying fiber optic cables in conduits is also known as blowing in.
Blowing machine for insulation materials
With the help of an insulation blowing machine , blow- in insulation can be introduced into a component. The loose insulation material is loosened and blown into the component to be insulated with the aid of a conveying air flow. Typical applications are the blowing in of cellulose thermal insulation material or mineral thermal insulation materials such as B. perlites or mineral wool . A blowing machine typically has a filling area in which the material is fed and a conveying part in which the insulating material is blown into a component via a hose . The loosening is mostly done with rotating raking units and chopping units. For sensitive insulation materials such as B. Perlite, it makes sense to use a machine with a purely pneumatic conveyor system. Because there is no agitator or chopping mechanism, the grain destruction is much lower. The specified properties of the insulation material are largely retained. The material is then conveyed through a blow-through lock via an air stream into a hose, which is laid into the component to be insulated.
Blowing machine for fiber optic cables
In addition to insulating materials, special blowing machines can also be used to blow fiber optic cables into empty conduits using foam washers for sealing and lubricating .
