LTA 2.0-CW™

GENERAL DESCRIPTION
The LTA 2.0-CW™ is a wall-mounted telescopic
extraction arm with a rotatable hood. Located in the
hood is a throttle valve that can be fully opened, par-
tially opened or completely closed to control airflow.
The arm features a focus extraction spoiler which
directs the air into the hood. The extraction arm is
based on a telescopic tube, allowing it to be extended
to give a 8.2 ft (2.5 m) working radius and com-
pressed to 5 ft (1.5 m). The arm is fitted with a spring
balance which enables it to be moved from a vertical
to a horizontal position in one easy movement. If
mounted on a column, the arm can be turned 300°
due to the rotating hinge. The LTA 2.0-CW™ is often
used in welding booths.
MANUAL OPERATION
The extracted welding fume enters the extraction arm
via the rotatable hood. The arm discharges the pollut-
ed air to a filter unit or directly to the atmosphere. The
hood of the arm is fitted with a throttle valve, which
can be controlled using the rotary knob(s). The throttle
valve is mostly used when several extraction arms are
integrated in a line installation; in such configurations
closing the throttle valve prevents the loss of costly
heated air.
NOTE: If an automatic damper system is part of the
assembly, keep the manual damper open at
all times.
