MANUFACTURING FEATURES
• Safety start-stop switches according to IEC 60947-1 and IEC 60947-3.
• IP65 and always equipped an auxiliary contact.
• Useful for switching off the current before handling the fan.
*Máx. thermal current air (A)
MANUFACTURING FRATURES
• Inlet protection guard to avoid the entry of objects and contact with the impeller.
• Made of galvanised steel models 7,9, 10, 12 and 15. And the rest of models with polyester powder finishing coat.
MANUFACTURING FEATURES
• Connection to be fitted in the centrifugal fans outlet.
• Manufactured in galvanized steel.
UNDER REQUEST
• Versions in stainless 304 and stainless 316.
MANUFACTURING FEATURES
• For axial (inlet and outlet) and centrifugal (inlet) fans.
UNDER REQUEST
• Versions in stainless 304 and stainless 316.
MANUFACTURING FEATURES
• Flexible joint to clinch the fan to the duct.
• Avoids transmission of vibrations for circular and rectangular connection.
• Dimensions: two metallic flanges of 45mm each one and a flexible flange of 60mm.
• The reel is 30,5m lenght.
• Maximum pressure: 20 mmca.
• Fire resistance M0 from -50ºC to +200ºC in continuous and 400ºC/2h.
MANUFACTURING FRATURES
• Outlet protection guard to avoid the entry of objects and contact with the impeller.
• Made of steel and protected against corrosion with polyester resin powder.
MANUFACTURING FEATURES
• Specially designed for speed frequency control in ventilation applications.
• Ultra compact, simple operation and wide range of functions.
*Dial panel incorporated. Optional EMC filter.
Certifications: CE/UL/CSA/EN/GOST/CCC.
Protection index IP20.
The selection of SFC frequency drive speed controller must be made based on the maximum intensity absorbed by the fan to be regulated. The powers (kW) and the intensity for constant load refer to the normal duty (150% overload for 60 seconds). The intensity for quadratic load admits an overload of 110% during 60s.
SFC 230: Entrance 230V I, exit 230V III
SFC 400: Entrance 400V III, exit 400V III
EMC filter incorporated for models from 47A (included)
*Lineal load rated current
**Quadratic load rated current
