Roof Fans
HTMH/ATEX
Multi purpose roof mounted fans for large airflow, with ATEX 2G or 2D certification and Ex db, Ex eb or Ex tb motor
Extremely robust, multi-purpose roof-mounted axial fans for large airflows. ATEX 2G or 2D certification with flameproof Ex db, increased safety Ex eb or dust ignition proof Ex tb motor to work in explosive gas or dust atmospheres.
Fan:
• Support base in painted galvanised steel sheet.
• Adjustable cast aluminum impeller.
• Protection grid against contacts according to UNE-EN ISO 12499.
• Cap in painted galvanised steel sheet, with natural air outlet.
• Standard marking with flameproof motor (Ex db): II 2G Ex h IIB T4 Gb.
• Standard marking with increased safety motor (Ex eb): II 2G Ex h IIB T3 Gb.
• Standard marking with motor for dust ignition proof (Ex tb): II 2D Ex h IIIC T135 ºC Db.
Motor:
• Class F motors with ball bearings and ATEX certification flameproof Ex db, increased safety Ex eb or dust ignition proof Ex tb.
• Single-phase 230 V 50 Hz and three-phase 230/400 V 50 Hz (up to 4 kW) and 400/690 V 50 Hz (powers greater than 4 kW).
• Working temperature: -20 ºC +40 ºC.
