A 5.7 Adjust the suction rate with
the 3-level selector switch 1
Establish the length of the exhaust ducting,
the number of bends required, outdoor air
damper or rain-excluding flap.
Calculation of the entire exhaust ducting
with a smooth pipe.
A 90° bend
equals 4 m of straight pipe
An outdor air damper
equals 4 m of straight pipe
A rain-excluding flap
Example:
38 m straight pipe = 38 m
8 bends equivalent to 4 m each = 32 m
1 outdoor air damper = 4 m
Total: 74 m
With diagramm “A“ these 74 m result in a
pipe diameter of at least 150 mm, and a
level II setting, for type 70 fume cupboard.
With diagramm “ “ these 74 m result in
pipe diameter of at least 200 mm, and a
level II setting, for type 120 fume
cupboard.
These values are approximate
performance ratings for smooth
pipes.
5.9.3 The customer`s connection, and the
capacity adjustement must be completed
and verified by an authorized specialist.
