Er 1253 UT N-LNE ENTRFUGAL FANS atent G25327 ALATON ompact duct in-line centrifugal fans suitable to extract air in commercial and industrial buildings such as factories, sports halls, shops, industrial units, warehouse, schools, kitchens, etc., where a large volume of air at a reasonably high pressure drop is required. ONSTRUTON The all metal fan casing and guard provide a long lasting and robust construction. The units have been constructed from mild ste and suitably treated to ensure full corrosion protection. The guard is powder coated polyester epoxy paint finish in black (RAL 95). Fan casings are powder coated polyester epoxy paint finish in past beige (RAL 732). High efficiency low tonal noise backward curved centrifugal impler, dynamically balanced to SO 14694 Grade G6.3 and directly driven by the motor to provide a smooth airflow through the unit. The units may have either an E or A external rotor motor fitted as standard. The motor contains sealed for life bearings. Thermal lass of motors to THL 13 or 155 dependent on size. All motors are suitable for use in ambient air conditions up to +6. Electrical connection to the motor is provided by an 55 terminal box. FEATURES & ENEFTS Unique in industry design (UK atent Number G25327) provides good pressure in a compact and easy-to-install unit, thanks to in-line configuration. Speed adjustable operation on A single-phase versions through Voltage or Frequency controller (Electronic, Transformer or nverter). Speed adjustable operation on E versions through potentiometer or WM controller. Ease of installation through external terminal box. Tested to the latest standards, meaning accurate, up to date information on ectrical safety, performance and noise lev (?) that can be ried upon. esigned and manufactured in accordance with Machinery irective (M), Low Voltage irective (LV), Electromagnetic ompatibility irective (EM), and Regulation 1253/214 (Er irective).
