For optimum extractor hood
efficiency:For optimum extractor hood
efficiency:
❑ Short, smooth air exhaust pipe.
❑ As few bends in the pipe as possible.
❑ Diameter of pipe to be as large as
possible and no tight bends in pipe.
If long, rough exhaust-air pipes,
many pipe bends or smaller pipe
diameters are used, the air extraction
rate will no longer be at an optimum
level and there will be an increase in
noise.
The manufacturer of the
extractor hoods accepts no liability
for complaints which can be
attributed to the design and layout of
the pipework.
❑ Round pipes:
We recommend
Internal diameter: 150 mm (at least
120 mm).
❑ Flat ducts must have an internal cross-
section that equates to that of round
pipes.
There should be no sharp bends.
l 120 mm approx. 113 cm
l 150 mm approx. 177 cm
❑ If pipes have different diameters:
Insert sealing strip.
❑ For exhaust-air mode, ensure that
there is an adequate supply of fresh air.
Circulating-air mode
❑ With activated carbon filter if exhaust-air
mode is not possible.
