Product descriptionThe UB 20xx axial fan is designed for ventilation and gas extraction in explosive atmospheres such as filling stations, fuel depots, tanks and manholes. The antistatic housing construction conducts electrostatic charges to earth to prevent dangerous sparking. The motor and housing meet protection class IP55 for effective dust and water resistance. ATEX marking: Motor/Housing: II 2 G Ex db eb IIB T6 Gb; II 2 G Ex IIB T6 Gb — suitable for Zone 1 and Zone 2.

Application notesObserve installation conditions and applicable hazardous-area regulations. If required, earth antistatic hoses. Devices with ATEX approval may be operated in Zone 1 and Zone 2; ensure correct classification of the area. The UB 20xx is intended for use with antistatic hose canisters and suitable earthing.
Shaft and channel ventilationWhen natural ventilation is insufficient (for example due to location or covers), mechanical ventilation is required. Powerful fans deliver fresh air directly to the worksite and reduce risks from toxic gases or oxygen deficiency. As an indicative value, aim for at least 600 m³/h per m² of duct cross-section where applicable.
