WARNING!
• Explosion risk! The NEX MD Arm must not
be used for extracting dust or fume air mixtures in explo-
sive environments.
• Check that no sparks or other objects which
can cause fire are sucked in to the arm.
• at horizontal link (B) on 4 m and 5 m
NEX MD arm.
User instructions (page 5)
The extraction arm can easily be positioned at any point
within its working area. It can be rotated 180° when wall
mounted and 360° when ceiling mounted. For best capture
the hood should be positioned as near the fume or dust gene-
rating process as possible. It has the best suction capacity
when it is positioned according to figure C.
Recommended airflow: 900 - 1300 m
check local directions. The hood is equipped with a damper
which can be adjusted with a lever (X).
Always check that the airflow is sufficient in the hood before
work begins. Insufficient airflow is depending on:
• The fan impeller rotating in the wrong direction.
• Hood, hose and 90°-bend are blocked.
• Filter cartridges are blocked.
90°-bend in hanging or standing position (page 5)
The NEX MD arm is recommended to be mounted according
to figure A, with the 90°-bend in hanging position. In excep-
tional cases the arm can be mounted according to figure B,
with the 90°-bend in standing position. However, the arm hol-
der must then be revolved 180°. See figure B1 and B2 for the
right position. Revolve the arm holder in the following way:
1. Loosen the four screws fitting the arm holder to the 90°-
bend.
2. Move the arm holder approximately 17 mm away from the
90°-bend.
3. Revolve the arm holder 180°.
4. Move the arm holder back towards the 90°-bend.
5. Fasten the four screws.
