Extractor fan UB 20XX

axialductfloor

In potentially explosive environments, the fan extracts hazardous gases safely and quickly. For ventilation in logistics warehouses and for remediation work in contaminated areas. For repair and maintenance work at petrol stations and tank installations, in manholes and tanks. For use in the chemical industry and for fire brigade operations. The housing made of a robust plastic material dissipates stresses into the ground and thus prevents static charging and dangerous sparking. The housing and motor seals comply with the high protection class IP 55 and provide effective protection against dust and water. Antistatic hoses ensure safe operation. ATEX: motor/housing: II 2 G Ex db eb IIB T6 Gb, II 2 G Ex IIB T6 Gb, Zone 1+2 Special features in potentially explosive atmospheres Installation conditions and the different hazardous areas must be observed; only connect the unit to explosion-protected mains sockets; ground antistatic hoses if necessary. Fans for explosive atmospheres Fans with ATEX approval may be operated in Zone 1 and 2. Zone 1 is an area in which a hazardous explosive atmosphere consisting of a mixture of air and flammable gases, vapours or mists is likely to occur in normal operation occasionally. The equipment is approved for substance group IIB. A typical gas for group IIB is ethylene with an ignition energy of 60 - 180 mJ. Ventilation of shafts If the existing natural ventilation in shafts and duct systems is not sufficient due to local conditions such as the location of the shafts or their cover properties, additional, technical ventilation measures become necessary.
