Axial fans with square plate mounted arrangement, (series DQ) are supplied with
inlet protection guards as standard on sizes up to 630 mm diameter. From size 710
mm upwards inlet guards are not fitted as a standard item. Guards can be supplied
as an optional extra if required.
Great care should be taken at the installation stage to ensure that it is not possible
to touch the impeller. If there is a possibility to do so, protection guards should be fit-
ted relevant to the local health and safety requirements.
−
Case mounted axial fans (series DR) are not fitted with protection guards as stan-
dard as they are usually positioned in a duct system which eliminates the possibility
of touching the impeller. However, should this type of fan be installed in any system
that leaves one or both faces of the fan exposed then suitable protection guards
must be fitted in accordance with local health and safety requirements. These
guards are available as an optional extra from our programme.
When installing please check whether it is excluded to touch the impeller. If touching
is possible a protection guard conforming to standards has to be mounted suitable
and tested protection guards can be supplied as accessory.
−

gramme).
