CMR/ATEX
Extremely robust, medium pressure centrifugal fans with a backward curved impeller, ATEX 2G or 2D certification and Ex db, Ex eb or Ex tb motor
Extremely robust medium pressure single inlet centrifugal fans. 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:
• Sheet steel casing.
• Backward curved impeller in highly robust sheet steel.
• Non-sparking inlet ring made of copper.
• Maximum temperature of air to be carried: -25 ºC +88 ºC (T4) or +120 ºC (T3).
• 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, IP55 protection. ATEX certification flameproof Ex db, increased safety Ex eb or dust ignition proof Ex tb.
• 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.
Finish:
• Anti-corrosive with ATEX paint, free of iron components, in polyester resin polymerized at 190 ºC, after degreasing with phosphate-free nanotechnological treatment.
On request:
