2. Application
ERGO-L/Z{2;3;4}/Ex and ERGO-L/Z{2;3;4}-R/Ex explosion-proof extraction arms are designed
for extraction the dust particles and gases arising during technological processes, whereby, (de-
pending on the local and operational conditions) exists the occurrence of explosive atmos-
phere, i.e. a mixture of flammable substances –in a form of dust particles and gases with the
air, in atmospheric conditions, in case of which (after the ingnition) the burning mass expands
within the whole rest of the not burnt mixture.
Do not apply the extraction arms for corrosive aggressive atmospheres and for environ-
ments containing viscous dusts.
ERGO-L/Z-{2;3;4}/Ex, ERGO-L/Z-{2;3;4}-R/Ex extraction arms are classified as appliances of
group II, category 2, of gas hazard Gand dust hazard Dand they carry the marking:
II 2 G/D c

group II –the device is designed for on-ground work in factories, in areas of explosion
hazard,

3
10.01.2019 explosion-proof extraction arms ERGO-L/Z-{2;3;4}/Ex

category 2 –the device should be constructed in such a way that it can work according to
the operational parameters, as appointed by manufacturer, providing high level of protec-
tion; devices of this category:
–
are adapted for use in areas where occurrence of explosive atmosphere is possible –
area 1(G) or 21(D)
–
are equipped with explosion protection measures –ensuring the required protection
level –even in situation of frequent interferences or faults that are taken into account.

gas / dust hazard G/D

admissible temperature of the forwarded air +70ºC
3. Reservations of Producer
A.
Manufacturer accepts no liability for any consequences following from the operational use
that is in contradiction to the purpose of application.
B.
Installing of any additional elements not belonging to the normal device structure (or acces-
sory set) is not acceptable.
C.
Do not undertake any structural changes or constructional modifications on the device on
one’s own.
D.
Protect the flexible elements and the duct segments from mechanical damage.
E.
Prior to installing check the load carrying capacity of the building structure where the device
will be mounted. Unsure mounting could cause hazard to personnel/people in vicinity and
effect in damage of the device.
4. Technical Data

5. Structure and Function
Extraction arms type ERGO-L/Z-(2,3,4)/Ex and ERGO-L/Z-(2,3,4)-R/Ex consist of
subsequent assemblies –as specified in the drawings (see pages 9 and 10).
●
full-rotation swivel (stainless steel),
●
lower joint –(connector, hose, hose clamps),
●
upper duct segment (stainless steel),
●
middle joint –(connector, hose, hose clamps),
●
lower duct segment with a shut-off damper, handle and hood joint (stainless steel),
●
suction hood –of non-sparking metal (stainless steel),
●
gas spring (stainless steel),
●
a set of copper cables –joining all the constructional elements of the whole ERGO/Ex
extraction arm and discharging the electrostatic loads to the grounding (dissipation).
A full-rotation swivel, of stainless steel (spark-proof execution) provides 360rotation of the
extraction arm around its vertical axle –thus giving the possibility of easy manoeuvring with
the extraction arm in the operational field.
To the swivel are connected ducts (upper segment and lower segment). These segments
are assembled together by means of flexible joints (i.e. hose-section of special execution
for application in areas of explosion risk, abrasion-resistant, surface impedance <1 GΩ).
The full-rotation swivel, the elements of the ventilation ducts (connected with flexible joints)
are forming a ventilation duct through which is extracted the contaminated air.
Position adjustment of the extraction arm (to the User’s requests within the operational field)
can be achieved within the normal workrange of the type of the specific device (2, 3 or 4m).
