1 Explosion proof fans General Systemair explosion proof fans have been developed to be used in effective supply and exhaust air systems allocated to category 2 (zone 1) and category 3 (zone 2) in explosion hazardous areas. All fans are manufactured in accordance with ATEX guideline 94/9/EG certified for EC countries. Certificates can be downloaded from our homepage. The fans are suitable for mounting in above mentioned explosion hazardous zones. Systemair ranges The materials used in Systemair EX fans are in accordance with DIN EN The fans of series DVEX, DVV-Ex and RVK-Ex are equipped with self-cleaning impellers with backward curved blades. EX, KTEX and DKEX are equipped with impellers with forward curved blades. AW-EX is equipped with profiled steel impellers with additional painting. The selection of an EX-fan Below Systemair provides you with helpful information for the selection of a suitable fan. We want to point out that we as manufacturers are responsible only for the appearance and workmanship of the fan. The system user is responsible for the correct system design for a proper operation. Pre-selection depends on the medium to be transported. Each medium has an individual ignition temperature. The fans supplied by Systemair comply with temperature classification T3, some units can also be used in T4. The next step is the selection of the correct zone resp. category. Basically the correct zone or category can only be given by the user of the system, after having conducted an analyse regarding the occurrence of explosion hazardous gases or gas mixtures in the project. All Systemair explosion proof fans are in unit category II, allowing an application in zone 1 and zone 2. In the industry, explosion hazardous areas are classified in zones. ATEX classifies the fans in categories, corresponding to the zones. Categories are independent from the substance causing the explosion hazard. The classification in categories (or zones) is related to the temporal appearance (frequency of occurrence) of explosion hazard - ous atmosphere (gas/vapour/fog-air mixture in ignitable condition). The categories or zones do not define the concentration! Category 1 (zone 0) covers areas, where there is a permanent or long lasting occurrence of explosion hazardous atmosphere (more than 1000h/year). Example: inside a fuel tank. Category 2 (zone 1) covers areas, where there is a regular occurrence of explosion hazardous atmosphere ( h/year). Example: Filling machine Category 3 (zone 2) covers areas, where there is a non-regular or short time appearance of explosion hazardous atmosphere (up to 10h/year). Example: defective gas pipe, accidents. i d e p o m q intrinsic safety pressure resistant capsulation increased safety overpressure capsulation oil capsulation cast capsulation sand capsulation The categories show the occurrence of an explosion hazardous area as a probability. It is important to know: In all categories (zones) there is the same momentary hazard (same substance and same concentration) when explosion hazardous atmosphere occurs. Example: zone 0, empty and noncleaned fuel tank, concentration 20Vol%; zone 2, leaked fuel, concentration 20Vol%. If an explosion hazardous atmosphere occurs, the hazard potential is the same in all zones! The last decision has to be made regarding the ignition protection class. All Systemair explosion proof fans correspond to ignition protection class Ex (e) = increased safety. The following table shows possible ignition protection classes. EEx q IIA T5 The ignition of an explosive mixture can be avoided by different ignition protection classes. Temperature Ignition temperatures of Admissible surface temperature classification different gas mixtures of electrical equipment T1 > 450 C 450 C T2 > > 450 C 300 C T3 > > 300 C 200 C T4 > > 200 C 135 C T5 > > 135 C 100 C T6 > 85...> 100 C 85 C The table shows the maximum surface temperature for each temperature classification. 238

Explosion proof fans Motors DVEX, AW-EX, KTEX, RVK and DKEX are equipped with speed controllable, certified external rotor motors in EXe execution.

2 Explosion proof fans Motors DVEX, AW-EX, KTEX, RVK and DKEX are equipped with speed controllable, certified external rotor motors in EXe execution. EX is equipped with non speed controllable IEC motors, Exe execution. DVV-EX is equipped with either single or two speed motors in Ex(d). This motor type can be speed controlled by frequency. All DVEX, KTEX, DKEX, AW-EX and RVK EX fan motors are equipped with a cold conductor for motor protection. The motor protection has to be connected with a motor protection device, described in the certificate and also certified. Motors of series DVV-Ex and EX do not have a thermal motor protection. Those motors have to be supervised by a suitable over-current device. The ignition temperature of the medium, but also the classification in explosion groups is important. Both classifications have to be considered (II A or II B) when selecting a suitable fan. A good example is hydrogen. Hydrogen is classified in temperature class T1, but in explosion group II C. Hydrogen can not be extracted with a Systemair explosion proof fan. Explosion group group II A group II B group II C Gases and vapours of substances acetone, ammonia, ethyl alcohol, fuel, benzene, methane, propane, carbon dioxide ethylene, diethyl ether, town gas hydrogen, carbon disulphide, acetylene.
