With the telescopic lance, the lance is inserted into the cavity and then the inner tube can be extended as required. This results in an effective doubling of the insulation cavity length which can be blown into. The telescopic feature also minimises the required workspace – even extremely long elements can be filled, since only the lance’s fixed length need be considered. All lances can be earthed against electrostatic charge development.

Lance length determination:
Effective length (lance extended) = length of compartment ±100 mm
Max. effective length (i.e. lance extended): up to 11700 mm available
