Rosenberg explosion proof axial fans are produced in accor-
dance with the latest technical standarts and our quality assur-
ance programme which includes material and function tests, en-
sures that the final product is of a high quality and durability.
Nevertheless these fans can be dangerous if they are improperly
installed by unskilled personnel or used not in accordance to the
specifications.

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.
−
Axial fans without casing (series ADK...Ex and AKD..Ex) for installation in units
a) without supporting suspension
b) with supporting suspension on one side and integrated protection guard
with installation in units the plan fitter is responsible for compliance of the security
regulations.
−
Only use the fan after it has been securely mounted and fitted with protection guards
to suit the application (Tested guards can be supplied for all fans from our pro-
gramme).
−
Installation, electrical and mechanical maintenance and service should only be un-
dertaken by qualified engineers!
−
The fan must only be used according to its design parameters, with regard to per-
formance (
data plate) and mediums passing through it!

Explosion proof axial fans were especially developed for the use in explosive areas.
The use of external rotor motors offers significant technical advantages compared to
conventional axial fans. All axial fans are continuously speed controlable in a voltage
range of 25 % - 100 % of the rated current and are statically and dynamically bal-
anced in our factory. The motors fulfil the requirements for protection type „e“ en-
creased safety and are certified as EEx e II T3, due its attestation of conformity. With
regard to possible breakdowns rotating and stationary components which could
come in contact are made of materials that reduce the danger of ignition and friction
sparks.

Motor data for the optimally cooled motor are listed on the
metallic data plate. These data are content of the PTB attestation
of conformity. Fan data are listed on the fan data plate (sticker).
In order to obtain a good speed graduation with voltage control it
is possible to select motors whose rated voltage is higher than
the rated voltage of the fan.

•Store the fan on a dry place and weather protected in ist original packing.
−
Cover open paletts with a tarpaulin and protect the fans against influence of dirt
(i.e. stones, splinters, wires, etc.).
•Storage temperatures between - 30 °C and + 40 °C .
•With storage times of more than 1 year please check the bearings on soft running
before mounting (
turn by hand).
•Transport the fan with suitable loading means (
weight as per enclosed chart).
−
Avoid a distortion of casing or blades or other damage.
•
Use suitable assembling means as e.g. scaffolds conforming to specifications.

guards must be certified to DIN 31001 or DIN 24167.
The unpacked fan has to be checked for transport
damages. Damaged fans may not be installed!
In hazardous areas connect components to a voltage
equalizing system.

•Axial fans with square inlet cone plate (series DQ)
−
Installation only on a flat surface on the drilled holes in the inlet cone plates
installation on an uneven surface may lead to deformation of the wall ring
and may result in the impeller rubbing the fan casing.
•Axial fans with installation flange in either direction (series DR)
−
These fans are preferred to be installed in duct systems
installation on an uneven surface may lead to deformation of the wall ring
and may result in the impeller rubbing the fan casing.
•Axial fans without casing (with or without protection guard)
Note that the impeller must rotate freely.
The space between rotating and fixed parts has to be at least 1% of the diame-
ter of the impeller but not less than 2mm.
The ringshaped gap between blade wheel and wallplate/casing has to be even.
•Any installation position is possible for all types and sizes.
−
Hole draw for condensate in rotor resp. stator must be clear.
When mounting with vertical shaft the hole for drain of condensate on the
bottom must be opened. The hole for drain of condensate on the top must
be closed.

•Electric wiring must be in accordance with technical connection regulations and
local regulations and national electric codes as per enclosed wiring diagram in the
terminal box or on the casing.
−
Ex- proof fans are supplied with 1m cable (from the casing) as a standart
−
Connection according to the wiring casing (data plate on fan casing)
−
Insert cable according to rules in Ex junction box (
Accessories) and seal it
(possibly „Water bag“)
−
Connect PTC for motor protection properly to a PTB-tested tripping device
according to PTB 3.53 PTC/A

The motor protection through PTC temperature
sensors records all anomaly operating conditions
and outside influences and disconnects the motor
from the mains supply in case of any disturbance.
Do not connect PTC to mains supply!
Standart motor protection switches must not be
used!
A reset locking device has to be connected at the
side of the main connector.

Before control of direction of rotation:
−
Remove any foreign matter from the fan.
−
Check impeller rotate by hand for soft running.
−
Mount finger guards, protection guards (
Accessories) or prevent entry to fan.
•Check direction of rotation as per direction arrow on the casing by briefly turnig on
unit.
−
Change direction of rotating by exchanging two phases.

Our fans are maintenance free with normal operation! When us-
ing them in the fringe range simple maintenance work may be re-
quired!
The ball bearings have been lubricated for life. After the life time
lubricant inside the bearings is used up the bearings must be
exchanged.
The grease life time of the bearings is: for normal use at
