A specially developped tube cleaning device for
blowing-through of the suction tube in a lift shaft.
The compressed-air device will be operated with
230V. Only with this efficient compressed-air device
is a building-up of a sufficient pressure volume
possible for best possible cleaning.
The compressed-air device is available at D+H with
the designation Pipe•Clean.
Separate the TITANUS
from tube
system before blowing free of
the tube system, because
otherwise the air flow detector
