Description
The design complies with EN 14986. In the impeller rotation zone there is an aluminum strip on the steel casing or ring, the impellers are cast aluminum, the cable glands are spark-safe, and the ATEX paint contains no iron components (polyester, 190 °C). The motor can be one of three types. With Ex db the marking is II 2G Ex h IIB T4 Gb, with Ex eb II 2G Ex h IIB T3 Gb, and with Ex tb for combustible dust II 2D Ex h IIIC T135 °C Db. The motors are class F, 230/400 V up to 4 kW and 400/690 V above 4 kW, 50 Hz, and the ambient temperature is from −20 to +40 °C. The HDF and HCDF fans have Ex db motors and the marking II 2G Ex h IIB+H2 T4 Gb for hydrogen.
How to choose
The type of explosion protection is determined by the motor. Ex db is for gases of group IIB, Ex eb with temperature class T3, and Ex tb for combustible dust. HCT/ATEX is a duct fan with an inspection hatch, HCH/ATEX is wall-mounted, HC/ATEX is wall-mounted with a protective guard to UNE-EN ISO 12499 in sizes 25–63, HPX/ATEX is a duct fan with the motor outside the airstream and a belt transmission, and HTM/ATEX is portable. For hydrogen HDF (sizes 63–90, up to 47 700 m³/h) or the more compact HCDF (sizes 25–56, up to 10 560 m³/h) is taken. The power of HPX/ATEX is 0.25–11 kW, with sizes 35–100.
