Page 6: General Considerations
remise GENERAL CONSIDERATIONS The fans conforming to the ATEX directive differ from stand- ard fans as they are built with special precautions in order to make them suitable to be used in poptentially explosive environments. In addition to the particular construction of the fan, particular monitoring and maintenance are critical so as to maintain the fan safety requirements over time and for its suitability for use in the potentially explosive environment it is placed in. -
Page 7: F Ield Of Application
ield of application General information The Manufacturer refuses any liability for any damage originating from incorrect or unwise operations. It is strictly forbidden and dangerous to use the product for different uses from those provided within the field of application. Normally intended use This fan was designed to: Product a flow of air, gas or steam by increasing their pressure,... -
Page 8: F Eatures
eatures SPECIFICATIONS Field of use of the manual This manual applies to the centrifugal fans of the following ATEX version series: Type Series CHAT CHBT Fluid Type Series Fluid Type/Series: Models available in different size configurations, orientation, direct coupling or joint or belt transmission. Treated fluid: G = Gas, D = Dust. -
Page 9: Categories Of Constructive Safety
eatures Categories of constructive safety The potentially explosive atmosphere can be caused by: - Gas, potentially explosive vapours and mists. - Dust, potentially explosive dust. - Gas and Dust, both. Depending on the duration of the potentially explosive atmosphere and its type, the risk areas are defined and shared with the customer;... - Page 10 eatures The INTERNAL and EXTERNAL CATEGORY of the fan can be different accord- ing to the different risk AREA INSIDE or OUTSIDE the fan. The basic rule between the INTERNAL and EXTERNAL category is as follows: - For fans that are not fully ducted, consider the same CATEGORY of the fan. - For fully ducted fans but in closed or poorly ventilated environments, consider the same CATEGORY of the fan.

Page 11: Conditions Of Installation And Use
eatures CONDITIONS OF INSTALLATION AND USE: Do not install, switch-on or perform maintenance on the fan and/or ancillary equipment if not completely certain that you are aware of and have the appropriate requirements concerning ATEX products. The fan operating data and nominal performance ratings are indicated in the relevant job documents and summarised in the attachment Ex. -
Page 12: Product Identification
eatures Product Identification The identification plate reports the serial number, some important data and the CE logo. The plates must NOT be removed or concealed under any circumstances. Another plate is installed in addition to the products suitable for explosion-proof environments (ATEX).

In a potentially explosive explosion-proof environment (ATEX) you must consider that the installation, commission- ing, maintenance and decommissioning require special care... -
Page 16: S Tart-Up
tart-up Before starting the fan you must know what is described above and rely on skilled professionals who are aware of all the problems related to explosion-proof environments (ATEX). In addition to this manual, consider all the requirements and information described in the basic manual for your model of the fan. -
Page 17: Checking The Distance Between The Impeller And Nozzle (Air Gap)
tart-up Checking the distance between the impeller and nozzle (air gap) Complying with the distance between the impeller and the nozzle is one of the most important parameters for a fan that works in ATEX environments. These fans are thoroughly checked but you cannot exclude a shift between the impeller and nozzle during the transport, commissioning or special maintenance. -
Page 18: Checks With The Fan Running
tart-up CHECKS wITH THE FAN RUNNING Speed of the impeller The impeller rotation speed limit is specified in the job documents as well in At- tachment Ex and on the fan plate. Fan flow rate and partialisation of the flow. The flow adjustment systems must be opened and closed slowly so as to avoid the risk of generating sparks which can create the risk of explosion. -

The following checks are to be carried out: 3,000 h 3000 hours - (1 hour) - Measurement of vibrations with mobile instrument 24 hours continuous - (0) - Continuous measurement of vibrations with... -
Page 20: Measurement Of Impeller Rotary Speed
aintenance Measurement of impeller rotary speed Measurement of manual rotary speed A calibrated rev counter is required for the manual measurement of the rotary speed of the impeller or the transmission shaft (with a mobile instrument). Check that the detected value of the number of revs (rpm) does not differ by more or less than 5% of the nominal speed for which the fan was designed. -
Page 21: Atex Maintenance Requirements
aintenance ATEX MAINTENANCE REqUIREMENTS For the fan to function properly in a potentially explosive atmosphere, the following steps must be carried out in addition to that indicated previously and as already described in the user and standard basic maintenance manual. The frequency of the checks can be enhanced at the discretion of the user/customer in the case of particular requirements or suspicious abnormalities. -
