   • 2.0 x FLC for 30 seconds every 30 minutes
Terminal box position LAK 4112-4180
   • Standard: On right side of the motor (facing d-end)
   • Mounting of terminal box on top or left side on request
Terminal box position LAK 4200-4280
   • Standard: On top of the motor (facing d-end)
   • Mounting of terminal box on top or left side on request
Blower position
   • Standard: On top of the motor non-drive end
   • Other positions on request

   • Blower is supplied without filter as standard
   • Filter on request
Bearings
   • Grease lubricated ball bearings as standard
   • For belt drive please contact our sales offices
Heat exchangers - Air/water (IC 86W):
   • Air/water exchangers are especially recommended for polluted environment
   • Standard is for clean water
   • For corrosive water on request

   • Position on top of motor as standard
   • Fan motor at N-end
   • Water connection flanges at right hand side (facing D-end)
   • Max water pressure 10 PSI
   • Max inlet water temperature 25°C
   • A water temperature rise of 8-10°C must be expected

   • For motors with low loads or a low incoming water temperature, a temperature regulator a temperature regulator is recommended to avoid condensation in the cooling air cicuit and to minimize water consumption
   • A constant speed fan circulates the internal cooling air. A polyamide filter is provided for carbon dust
Heat exchangers - Air/air (IC 666):
   • Air/air exchangers are recommended where water is not available for cooling purposes
   • The output of a motor with air/air exchanger will be approximately 20% lower compared to cooling forms IC06/17/37/86W

   • Position on top of motor as standard

   • Two constant speed fans at top of the heat exchanger to provide air circulation for the outer and inner circuits
